PROCEEDINGS O F T H E TWENTY-PIFTH ANNUSL MEETING O F T H E AMERICAN SOCIETY OF ZOOLOGISTS NASHVILLE, TENNESSEE, DECEMBER 28, 29, 30, 1927 The 1927 meeting of the American Society of Zoologists was held at the Vanderbilt University School of .Medicine, Nashville, Tennessee, December 28th, 29th, and 30th. The local arrangements for the meeting were admirably carried out, and the meeting was a most successful one. The sessions for formal paper reading were unusually well attended, the attendance frequently running up t o one hundred or more. The success of last year's informal laboratory program was repeated this year. The laboratories in which demonstratio-ns and exhibits were open f o r inspection were crowded, and the comments were enthusiastic. The Secretary was the only officer or member of the Executive Committee present. The following letter from the President, Dr. S. J. Holmes, who was incapacitated by illness, was read at the opening session: To the American. Society of Zob'logists: I keenly regret that, on account of a recent illness, coming a t a most inopportune time, I am rendered incapable of attending the meetings of the American Society of Zoologists a t Nashville. But while expressing my disappointment over my enforced absence, I wish also t o express my high appreciation of the honor which the Society has conferred upon me in making me its president during the present year. With best wishes for a highly profitable meeting, Respectfully, S. J. HOLMES. 321 322 AMERICAN SOCIETY O F Z O ~ L O G I S T S TNTRODUCED P A P E R S By consent of the Society, the following papers were iiitro duced : IfORPHOLOGY A N D ASEXUAL STAGE O F EUGLYPHA ALVEOLATA PHILIP M. JONES Johns Hopkins Srhool of Hygiene nnd Public Health Rend Euglgpha alveolata has been cultured in a semipnre culture of I<nop’s solution and bacteria for five years. 1 have been able to confirm Schweiakoff’s work on the division of the nucleus, except in certain details. The substance around the nucleus which secretes the shell plates may be mitochondria. The staining reaction, movements during cell division, and reorganization of this substanre, the formation and movements of the protoplasm in both the mother and daughter cells during such formation, and the amoeba stage and its activities have all been studied. THE CALCIUM-ALKALI RATIO IN CULTUREMEDIA FOR PLANARIA DOROTOCEPHALA MARGARET R. MURRAY National Eesearch Fellow, UnivPrsity of Chicago (Introduced by C. M. Child) Read The object of this paper is to show that, for maintaining the normal form and functions of at least certain cells of the flatworm Planaria dorotocephala, a higher proportion of Ca t o K i n the medium is required than is contained in the usual ‘balanced salt solutions’ for vertebrate tissues. The amount of the calcium salt must be at least twice by weight the amount of the potassium salt, and may be as high as forty times without unfavorable effect. The amount of sodium may be diminished to a fraction of the amount of calcium, so long as the necessary osmotic pressure is maintained. An insufficient amount of calcium in the medium produces, in this form, general paralysis and inhibition of the normal wound contraction, which functions must be dependent upon the external epithelium and the muscle cells which lie just below it. Correlated with these findings is the fact that the springs in which the animals are found contain a n exceedingly high proportion of calcium t o the other salts; sodium and potassium are present in negligible amounts, calcium as 53 parts per million. 323 PROCEEDINGS THE POSSIBLE BIOLOGICAL SIGNIFICANCE O F T H E INCREASED X-RAYED TYROSINASE ACTIVITY O F ROBERT T. HANCE University of Pittsburgh Read The organic pigment, melanin, wherever found in the animal or plant kingdoms, is produced through the interaction of tyrosine and tyrosinase. When potatoes and mushrooms that contain a large supply of free tyrosinase are x-rayed, the enzyme exhibits a power of producing melanin i n reaction with tyrosine t h a t is increased in direct proportion to the length of the exposure. As the enzyme is a n oxidase its increased activity suggested a change in its powers of oxidation. Subsequent exposure of potato mush t o the air f o r short periods was also found t o increase the oxidizing powers of tyrosinase in proportion t o the length of the exposure. Lastly, the possibility t h a t these changes i n the oxidizing power of tyrosinase by x-ray might be reflected i n the metabolism of exposed living material was borne out when it was shown t h a t respiration of x-rayed mushrooms, potatoes, and mice was increased approximately 30 per cent following exposure. These three lines of evidence strongly suggest t h a t x-rays stimulate the oxidative processes of biological material. SIODELS ILLUSTRATING T H E DEGREE OF DEVELOPMENT OF SKELETON, MUSCLES, FORE L I M B OF T H E ALBINOR A T AT APPROXIMATELY T H E TIME IN FETAL LIFE W H E N MUSCULARMOVEMENTS BEGIN, BUT BEFORE MOTE MENTS I N TRUNKOR LIMBSCAN BE EXCITED' AND NERVES O F T H E HOMER BLINCOE Emory Uniacwity and The Wista?' Instittcte of Anotoniy (Introduced by G. E. Coghill) B y demonstratton Following the work of Sweiison on the behavior of the fetal rat, it seemed of value to investigate the state of debelopment of the anatomical structures having t o do with movements. The serial sections of a 12-mm. embryo albino rat of the approximate age when movements become evident (prwiously testcd and having been found negative as to movements) were studied, giving especial attention to the fore-limb region. Using thc low power of the inicroscope, muscle groups were shown to be well differentiated from the premuscle masses and attached t o the skeletal elements nearly as f a r as the paw. The nerve trunks are remarkably developed and show the usual relationships t o the muscles and skcleton. To visualize these anatomical features grossly, three wax reconstructions of the fore limb, after the methods used by Lewis in studying the development of the arm in man, were made, and these afford the unaided cyc a three-dimensional 'This paper was listed in the program a s l l l a , but owing t o an error the abstract was not included. 324 AMERICAN SOCIETY OF ZOOLOGISTS view of the aforementioned features. The muscle groups with their attachments, the skeleton, the nerves and their derivation from the brachial plexus, and the relationships of each to each are plainly shown. This study also contemplates the investigation of the cytological aspect of the developing muscles and the nature of the nerve-muscle connection. The possible bearing of these observations upon the question of self-differentiation of tissues is considered. AN UNFERTILIZED TUBALOVUM FROM THE MONKEY,MACAWS RHESUS EDGAR ALLEN University o f Missouri School of Medicine B y title This is the fourth unfertilized primate ovum to be recovered from the uterine tube. Observations and measurements were made while fresh in Ringer’s solution. The ovum was free from follicle cells and enclosed in a zona pellueida 1 5 p thick. An average diameter (including the zona) was 1 7 8 . 5 ~while ~ the ovum proper (excluding the zona) was 1 0 4 ~ . Measurements of other tuba1 ova from monkeys are given in table 6, Carnegie Pub. no. 380. As these measurements indicate, the zona fitted the ovum loosely, leaving a space of about 20 p between it and the ovum. The yellow yolk mass with polar body attached moved easily and could be rotated within this zona. As the ovum rolled, a clear polar cap covering about one-third of its surface became visible, then it rolled back with the polar cap on top. The ovum was observed during fixation with Bouin’s fluid diluted with Ringer’s solution. As the fixative diffused about the ovum the zona collapsed k~one-half its former thickness and ruptured, emitting a clear fluid which set upon contact with the fixative. An attempt was made to prepare the ovum as a whole mount, but gradual dehydration proved too severe a treatment, causing the fragmentation of the ovum. An empty half zona was all that could be identified. It appeared to be pitted (perhaps perforated). AN METANEPXROS I N RELATION TO VASCULAR SYSTEM ANALYTICAL STUDY OF THE THE ALICE L. BROWN Cornell University Medical College and Memorial Hospital (Introduced by Prof. C. R. Stockard) B y title The material used in this study was secured from thirty-eight cesarean operations on mice, in collnboration with Dr. Halsey J. Bagg. One hundred and fortysix embryos were obtained, 120 of which have been sectioned serially and the kidney regions studied in detail. These embryos range in age from nine days to term. A study of kidney anomalies classified these embryos as to the amount of PROCEEDINGS 325 blastema present into five groups: I ) embryos minus right or left kidney; 11) embryos minus both kidneys; 111) embryos with an arrested blastema and a retarded blastema; I V ) unusual cases; V) control embryos and those which appear t o have a normal kidney development. The ureter retardation positions fall into six groups: 0) those with no trace of a beginning; I) those in which a start was made, but never grew out; 11) those in which the ureter grew out to the umbilical-iliac artery; 111) those in which the ureter grew out to the level a t which the miillerian ducts are fusing; I V ) those which grew out to the pelvis brim, and, V) those which made posterior contact with the blastema and grew out t o the position of the normal kidney pelvis. Serial section study and reconstruction models of eleven different embryos a t critical stages within the nine- t o fourteen-day period prove the dominant factors in these anomalies t o be: An aberrant vascular system failing to produce a normal balance in development, and this in time causes an abnormal posterior twisting of the body during the ten- t o twelve-day period of development. This posterior twisting produces a crowding of the metanephric blastema and prevents the ureter bud from growing into i t ; and the stretching on the other side either prevents the bud from reaching the blastema or causes it t o reach only the most posterior part of the blastema, or separates the blastema into two parts. The kidney anomalies are, therefore, directly due to a failure of the metanephric blastema and ureter bud t o make a mutual union, and thus produce a functional kidney in whole or part. This twisting of the body produces a great distention of blood vessels, which normally brings about certain differentiations of mesenchyme a t this stage of development; abnormally, it produces a minus right or left umbilical artery before the fifteen- t o sixteen-day stage, a t which time one normally degenerates. Absorbing embryos observed in the thirteen-to-fourteenday stages are thus accounted for. Microscopical observations and models demonstrate that these factors account for all observed anomalies found in later stages of development embryos, i.e., a minus right or left kidney or minus both kidneys, or an arrested condition and retarded condition. Both the blastema and ureter bud are responsible for the defect, but evidence is in favor of the greater responsibility being on the blastema. THE INFLUENCE OF WHOLEPITUITARY AND POSTERIOR PITUITARY ON MATURITYOF PINK-EYED YELLOW RATS= THE DEVELOPMENT AND G . P. THOMPSON, F. E. CHIDESTER; AND A. G . EATON West Virginia University By title 1. Young pink-eyed, yellow rats of pure stock, receiving dosages of 0.15 gram and 0.30 gram of desiccated whole pituitary by mouth, grew a t abbut the same rate as the controls for the first five weeks, but gained much more rapidly than the controls for the remainder of the experimental period. The two different dosages gave practically the same results. 2Approved for publication by N. J. Giddings, acting director of the West Virginia Experiment Station, as Scientific Paper no. 42. Subsidized by the Purnell Fund, the Merrill-Soule Co., the G. W. Carnrick Go., and the Eli Lilly Co. 326 AMERICAN SOCIETY OF Z O ~ L O G I S T S 2 . Incrclascd growth in rats fed on desiccated whole pituitary is much more marked in male than in female rats. 3. Contrary to some beliefs, no cases of viciousness or gigantism developed. 4. A n apparently adequate basic diet consisting of ‘Klim’ and whole wheat may have accounted f o r the superior ‘self-control’ evinced by these animals. Other invrstigators have noted extreme nervousness in rats on pituitary cxperiments. 5. Desiccated posterior pituitary fed by mouth in dosages of 0.15 gram and 0.30 gram had very little influence on growth.

CHIDESTER‘ West Vtrgznaa Universzty B y title 1. Chicks fed dcsiccated suprarenal medulla grew almost the same as the controls for the first three weeks. A f t r r t h a t time, their growth was less rapid than the controls. 2. Chicks fed desiccated suprarenal cortex grew much more slowly a t first than the controls. But, by the end of the first eight weeks, they began t o grow more rapidly, and, toward the end of the experiment, almost equaled the controls in weight. 3. I f the woights of the testes are any indication of maturity, males receiving desiccated suprarenal eortcx wcre more mature than either of the other lots, and those receiving desiccated medulla wrre less mature than those of the other lots. The average weight of the testes of the lot receiving desiccated suprarenal cortex xvas 0.2171 gram; the average of those receiving medulla was 0.1342 gram, while that of thc controls was 0.2000 gram.

Growth of young rats is retarded by 0.5 gram of either desiccated suprarenal medulla or coitcx and is retarded, especially at first, by desiccated suprarenal cortex. 2. Young female rats fed 0.5 gram of desiccated suprarenal cortex (as shown by earlier litters) reach sexual niaturity sooner than controls or those fed on 0.5 gram desiecatcd suprarenal medulla daily. 4Approved f o r publication by N.

AGGLUTINATION PIIENOMENA IN AGINGGERM C E L L S A. J. GOLDFARB C o l l ~ g eof the C i t y of New P o r k B y title Lillie's studies on agglutination have been carried further with respect t o aging eggs and aging sperm. It has been demonstrated t h a t aging eggs increase the quantity of agglutinin. The rate of increase depends upon the physiological condition a t the time of shedding. On the other hand, aging sperm likewise increases the agglutinin reaction. This increase occurs later in the aging cycle than in eggs, but this increase in agglutination time is not due t o the formation of a n X substance either by the eggs or the sperm, b u t by a change in permeability which makes the sperm more reactive t o a given quantity of agglutinin. 'rIlE POSSIBLE EIOLOGICAL SIGNIE'ICANCE OF T H E I N C R E A S E D ACTIVITYO F X-RAYED TYROSINASE ROBERT T. H A N C E Unaversity of Pittsbiirgh B?J title The organic pigment, melanin, whcrever found in the animal or plant kingdoms, is produced through the interaction of tyrosine and tyrosinase.

Lastly, the possibility t h a t these changes in the oxidizing power of tprosinase by x-ray might b e reflected in t h e metabolism of exposed living material was borne out when it was shown t h a t respiration of x-rayed mushrooms, potatoes, and mice was increased approximately 30 per cent following exposure. These three lines of evinence strongly suggcst t h a t x-rays stimulate the oxidatil-e proces.;es of biological niaterial. THE REACTION O F I~O~VOZYGOUK AND HETEEOZTGOUS -4DULT THE INFTLTENCE OF X BATS CHARACTERS UNDER ROBERT T. HANCE Universzt y of Pit t s b u r g l ~ B y title To test the physiological strength of adult charactcrs determined by one nr two genes, pure-bred and hybrid agouti (wild gray color) mice were given the smallest exposure to x-rays that would be likely to inhibit pigment production in 328 AMERICAN SOCIETY OF ZOOLOGISTS the hair. Exposures of 30 KV., 22 ma., 26-em. target distance for five minutes were used. The agouti of the heterozygous mice was replaced by white, while that of the homozygous animals was replaced by hair distinctly darker than the original. It is believed that the determiner of the heterozygous agouti, being physiologically weaker, was destroyed, while those of the pure agouti were stimulated to greater pigment production. GESTATIONIN A MONKEY(MACACUS RHESUS) CARL 6. H A R T N A N Departnwnt of Embryology, Carnegie Institution of W a s h i n g t o n B y title For the first time it is possible to state accurately the length of gestation in any primate other than man. Six lunar months practically to a day intervened between mating and parturition in a female rhesus monkey of our colony. The animal was mated seven times ; sir infertile matings avoiding the theoretically fertile period of the interval, namely, nine to twelve days after the beginning of menstruation. The fertile mating occurred a day or two before the leucocyte count of the vagina had reached zero. After the low leucocyte count has been reached, the mating is sterile, which is further presumptive evidence for the short viability of the discharged ovum. From the fourteenth day after mating and continuing twenty-three days without cessation small amounts of blood were found in the vagina. This probably constitutes the placental sign of Long and Evans ( r a t ) and is due presumably to leakage from the placenta. This phenomenon is regarded as a n early sign of pregnancy and should be looked for in man. PROGRA4M Fifty-one papers were scheduled t o be read, exclusive of joint programs. Forty-two of these were read, the remaining nine being read by title. Forty-four other papers were scheduled by title.

Kornhauser, representative of the Society on the Executive Committee of the Commission €or the Standardization of Biological Stains, presented the following report for 1927 : To the Oficers and Members of the American Society of ZoGlogists: As your representative on the Commission for the Standardization of Biological Dyes, I wish t o report progress during the past year. Beside the regular work in testing new hatches of dyes f o r certification, the Commission has made important contributions t o our knowledge of dyes and has published many of these in “Stain Technology.” Most useful t o us is the work on tliionin and the azures, which can he used a s routine stains with eosin 330 AMERICAN SOCIETY OF ZOOLOGISTS for ordinary histological work and give most splendid results with a great variety of tissue a f t e r any of the ordinary methods of fixation. Your representative has used this technique with excellent results and can recommend i t to you heartily a s a rapid, differential, and easily controlled method. Improvenients and innovations have been made in fat-soluble stains, so that now a variety of good, strong stains f o r adipose tissue can be had which are f a r superior t o Sudan I11 of the past. A substitute permanent green for light green so much used in the Bends safranin-light green technique is being tested out. I t is hoped t h a t this substitution will do away with the fading of the green stain so annoying in the older technique. Your representative was present at a meeting of the Executive Committee a t Nrw York October 8th. Plans for the coming year were discussed. “Biological Stains” will appear in revised edition. “ S t a i n Technology” will continue to publish progrrss on the dyes and methods of staining and will also publish a series of articles on the history of staining. Both these publications have been well accepted and have more than paid f o r their cost of publication. It is hoped that if any member of the American Society of Zodogists has any particular problem in regard to stains or has any complaint t o make relative t o American microscopic dyes, especially those certified by the Commission, he will iiotify your representative or the Chairman of the Cornmission. Respectfully submitted, 8. I. KORNIIAUSER. The Society accepted the report and ordered that Doctor Kornhauser continue in the same capacity. Through the Secretary, the following report was presented €or the information of the Society : NATIONAL RESEARCH COUNCIL Eeport to the American Soceety of Zoologists on the work of the Dzvision of Biology and Bgricwltwre which may be of anterest t o the Society The National Keseareh Council, a cooperative organization f o r the promotion of scientific research, is founded on the principle o f representation through the national scaientific societies. Taking the Division of Biology and Agriculture as a n example closest t o our interests, fifteen societies in both the pure and the applied fields of biology a r e given opportunity, 1) to select someone from their respective memberships to constitute, with several members-at-large chosen by the Division a s a whole, the membership of the Division; 2 ) t o bring t o the Council the research needs in their own fields which this body may be in a position to encourage, and, 3 ) t o take a n active part in the general work of the Division. The history of the Division has indicated that this plan for serving the scientific groups of the country has worked ont unusually well. Already a dozen or so outstanding achievements have resulted and are now operating independently as major activities in the realm of science. The work PROCEEDINGS 331 of the Council, like its membership, is a continuing process, and each year a s certain projects branch out to stand alone more or less, new ones arise. Consequently, there is a t all times a large list of active projects. Those t h a t may be of interest especially t o the members of the American Society of Zoologists a r e briefly reported upon below. 1. C o m m i t t e e on Aq?tict~Ztwe. This committee was established i n 1925 for the consideration of the general subject of aquiculture and its probable relations t o conservation of waters in streams, lakes, and soils, and thus t o agriculture, forestry, and the general welfare. The present aim of the Committee embraces a thorough survey of the whole subject of aquiculture, particularly as t o the development of its scientific aspects in Europe and other countries, and t h e existing facilities f o r scientific training f o r this field in America, and a roundtable conference of those primarily interested in this country with a few leaders from abroad. Efforts a r e being made to find financial support f o r both the survey and the conference. 2. C o m m i t t e e on AnzmaZ Breedzng. This committee has been operating since 1924, first under the chairmanship of Dr. L. J. Cole and, beginning with J u l y of 1926, with Mr. E. N. Wentworth a s chairman. The two major problems now before its subcommittee on Methods of Analysis are, 1) correcting production f o r age in dairy cows and, 2 ) the development of methods which will providc a n accurate test and measure of the worth of the dairy sire. The subcommittee on Survey of Research plans to ascertain the various projects in animal breeding being conducted at the experiment stations, that the information may be available f o r general use. 3 . T h e Cornmattee 0% the Atmosphere and Man was established in the spring of 1921 primarily for a study of the relation of air to health. A t its initial meeting in the fall of 1921 it determined upon the following projects to engage its attention f o r the time being: 1) variation of influenza from citp t o city; 2 ) mortality in New York City; 3) factory records; 4 ) laboratory experiments. With financial and other material support, the committee has been enabled to go ahead with the first three studies and has published the following to date: Causes of geographical variations in the influenza epidemic of 1918 in the cities of the United States.

This committee was established at the request of the Huntington Family Association, who desired a n advisory and scientific committee in the National Research Council to help t h e Association in its proposal t o inaugurate a scientific record keeping of the physical and mrntal characteristics in the successive genrrn tions of the family. The Council, through 332 AMERICAN SOCIETY OF ZOOLOGISTS this Division, gave its endorsement, a n d the Committee has been a t work since 1922. Dr. Clark Wissler, of the American Museum of Natural History and Yale University, is the present chairman. Some funds for the committee’s work have been secured and a comprehensive questionnaire has been prepared f o r obtaining the desired records. The program of work as outlined will require a period of about five years t o bring t o some conclusion. 5. Committee on Pood and Nutrztion. This is a carry-over from the war organization of the National Research Council. J n reorganizing it in 1919, the committee was made up of two subcommittees, one on animal nutrition and the other on human nutrition. The committee has published mostly in the animal field a s listed: Cooperative experiments upon the protein requirements f o r the growth of cattle. First report of the subcommittee on Protein Metabolism in Animal Feeding. H. P. Armsby, chairman. June, 1921. Bulletin 12, N.R.C.

Bulletin 55, N.R.C., March, 1926. 6. Committee on Infectious Abortzon. Activities in the field of infectious abortion were first initiated in the Council through several conferences held over a period of t,wo or three years, beginning in 1921, a n d since 1924 a committee, first under the chairmanship of Dr. L. W. Goss and now with Dr. Theobald Smith acting in this capacity, has served as a nucleus for promoting cooperative work in this connection. 7. Baologzcal Abstracts. Since the establishment of the Council, this Division in particular has been concerned especially in a study of publication needs, with a view to attempting t o meet some of these. As a first step in this direction was the launching of International Biological Abstracts. This abstracting journal expects to cover the whole field of biological and closely related sciences. 6 . Committee on Research Publicatzons. The Division has further been concerned with a study of the needs among scientific biological journals for the publication of original research articles. Dr. C. E. McClung has been chairman of this committee during the past few years, but, inasmuch as he is out of the country now f o r the full year and it is felt desirable t o push this study this winter, the committee is being reorganized. 9. Fellowships growing out of actzvzty o f the Davzsion. I n addition to a number of special fellowships, funds for which have been made available a t various times f o r the support of particular pieces of research, there has been operating since 1923 a major series of fellowships known as the National Research Fellowships in the Biological Sciences and designed primarily for the PROCEEDINGS 333 training and development in fundamental biological science of individuals beyond the doctorate stage. The special fellowships which may be of interest to members of the American Society of Zoologists are the Sulphur Fellowships, the National Live Stock and Meat Board Fellowships, and the Rosenwald Fellowship. 10. Commission on the Standardizatzon o f Bzological Stains. This organization is now independent of the National Research Council except that the latter acts as its fiscal agent. It was established in 1922 for the development in this country of standardized stains, and its activities are no doubt well known by now. 11. American T y p e Culture Collection. This is another project which is now separated from the Division, but which it may be of interest to report on Here briefly. Following earlier arrangements for its maintenance, the Division of Biology and Agriculture, in cooperation with the Division of Medical Sciences, was asked by the bacteriologists to appoint a committee to study the situation and determine upon some plan whereby the collection might be provided for in a more permanent way and allow for its development on a scale which would meet the needs of the biological centers using these cultures. Early in 1925, support f o r the collection was secured through the General Education Board to the extent of $24,000 over a period of five years, and housing and other privileges were accorded it by the McCormick Institute for Infectious Diseases in Chicago. 18.

The Institute for Research in Tropical America was organized, under the auspices of the Division of Biology and Agriculture, in January of 1921 for the purpose of promoting “research in Tropical America, by exploration, by the establishment of laboratories and research stations, by coordinating the efforts of cooperating institutions, and by such other methods as the Institute may adopt.” Since its organization the Institute has concentrated its energies largely upon the establishment of the Barro Colorado Island Biological Station in the Panama Canal Zone. The assistance of the Nationnl Research Council was sought in endorsing this project to the government of Panama to bring pressure to bear on seruring the site desired for this Station. The Council gave its endorsement. The reserve was subsequently set aside, and, with Dr. Thomas Barbour in charge, plans for the establishment of the Station went forward without delay. It has been a going concern since the summer of 1923 and has received financial support from various sources. Some seventy-five persons, at least, have made use of the facilities a t the laboratory during the few years of its operation. 1.9, Commzttee on Tropical Research. The project a t present under the advisement of this group is the establishment of a graduate school of tropical agriculture. On the basis of study of a number of possible sites and following visits by the Division chairman of last year and the present chairman, the committee, with the endorsement of the Division, is recommending Porto Rico as the most suitable location for this proposed graduate school. On behalf of the Division of Biology and Agriculture, its present officers wish to call the attention of the members of the American Society of Zoologists to the fact that the National Research Council welcomes the representation on it of the Society and that the Division is the unit through which the Society secures this representation and t o whom it may bring any matters in which the Council can be of assistance. The extent t o which this Society, along with the 334 AMERICAN SOCIETY OF ZOOLOGISTS others included in this one unit, utilizes the Division organization a s a means t o arcomplish some of its needs, is the extent t o which the Division itself will justify its value to the societies. The report of the Secretary showed the membership of the Society to consist of 6 life members, 423 active members, and 51 associate members, making a total of 480. The election of 16 new active members, of 4 associate members to active membership, and of 10 new associate members later in the meeting brought the total up to 506. Two active members, A. D. Howard and 0. W. Hyman, and two associate members, Ruth Ball and E. E. Engle, resigned during the year. Three active members, C. H. Eigenmann, H. G. May, and C. C. Nutting, died during the year. Two of those elected to associate membership at the 1926 meeting, J. C. Donaldson and Mary Stuart MacDougall, declined election. The report of the Secretary was adopted and ordered filed. Through the Secretary, the Treasurer submitted the following report: TREASURER'S REPORT Report of the Treasurer of the American Society o f Zodogists for the year 1927 Credats: Balance on hand December 23, 1926, when accounts were $1127.71 last audited .......................................

Hargitt, reported the books t o have been examined and to have been found correct. Their report was accepted and ordered filed. The Necrology Committee submitted minutes on the deaths of three members which occurred during the past year. The minutes were adopted by a rising vote, and were ordered spread on the records. Copies of the minutes were ordered sent to the families of the deceased. Minute on the death of Carl H . Eigenmann Carl H. Eigenmann was born March 9, 1863, at Flehingen, Germany, and died April 24, 1927, at Coronado, California. H e came to America while still a boy and located at Rockport, Indiana. All his collegiate work was done a t Indiana University, where he obtained the degrees A.B. (1886), A.M. (1887), and Ph.D. (1889). He was made Professor of Zoology at Indiana University i n 1891 and Dean of t h e Graduate School in 1908. He had been i n declining health some years prior to his death, the decline probably beginning a f t e r contracting a fever while on one of his collecting trips to South America. It was the contact with Jordan while a student which aroused Doctor Eigenmann’s interest in zoology, a n interest which never lagged and which, coupled with his enthusiasm and determination, carried him through the tremendous amount of work which he did. Doctor Eigenmann’s contributions to zoology centered about three fields of interest. The first was a pioneer piece of research on the history of the sex cells in Cyrnatogaster; the second was his work on degenerative evolution with the blind vertebrates of North America. His third and greatest piece of work was his study of the fresh-water fishes of South America, a study planned in his younger days, but dropped temporarily during the studies on Cymatogaster and the blind vertebrates. These studies gained for Doctor Eigenmann world-wide recognition as a great zoologist. I n America THE AN.4TOMICAL RECORD.

Judging by the number of present-day zoologists who have been students under Doctor Eigennmnn, his influence as a teacher was more than ordinary. IIis method of work and particularly his energy and enthusiasm inspired his students. As a colleague within his department, he was exceptionally agreeable and stimuhtting t o the younger men. H e always kept in mind their interests and the interests of his former students. As :t man he was liked by all. His smile, liis ready wit, and his stock of storirs made friends whcrever he went. W.

H e received the degree of B.S. at t h r University of Rochester in 1913 and P h D . from the University of Illinois in 1917. After graduation he became associated with the United States Department of Agriculture as junior zoologist and in 1918 served in Dijon, France, for nine months a s bacteriologist in the United States Army, being concerned primarily with the bacteriology and pathology of wounds. During the gear 1919-1920 he was professor of biology in Mississippi College and, in 1920, was appointed professor of bacteriology a t Rliode Island State College and chief of the Division of Animal Breeding and Pathology a t the Rhode Island Agricultural Experiment Station.

DUNK. iwznutr on the tlrtclh of C1iarlP.s Cleveland Nuttzng The p:rssing of Professor Nutting, on the 23rd of last January, removed from among his fellows one of tlie oldest members of this Society, a n able teacher, a skillful invcwtig:itor, i i cultured gentleman, and one who was to many a belo%edfriend. Charles Clevelaiid Nutting wiis horn a t Jacksonville, Illinois, May 25, 1858, being the son of a clergyman. His alma mater was Blackburn College, Illinois, from which he received the degrees of A.B. in 1880 and of A.M. in 1882. I n 1926, Cornell College, Iowa, conferred upon him the honorary degree of LL.D. I n 1886. he becime a member of the faculty of the University of Iowa a s professor of zoology and curator of the Museum of Natural History, and after the lapse of four years was made head of the zoology department. This and the euratorship he retained till 1926, when he relinquished all administrative duties. Ilc continued t o teach, however, until five days before his death. PROCEEDINGS 337 As a teacher, his overflowing enthusiasm and never-failing energy acted as a n effective stimulus to students who were so fortunate a s t o come under his instruction, a n d as a constant source of inspiration to his colleagues. To collect specimens for the museum under his charge and to secure material f o r his researches, mainly in the field of marine zoiilogy, Professor Nutting traveled widely. In 1881 and 1882, he engaged in explorations in Central America f o r the Smithsonian Institution, aiid thereafter he visited in turn Costa Riea (1882), Nicaragua (1883), Florida (188-5), the region of the Saskatchewan River in Canada (1891), the West Indies (1888 and 1893) ; the zoological stations a t Plymouth, England, and Naples, I t a l y (1895), the Hawaiian Islands (1902, a s a civilian member of the Hawaiian cruise of the U. S. S. Albatross) ; LaJolla, California, and the Pacific coast (1903 and 1909), and Barbados (1917). H e led three expeditions from the Uiiiversity of Iowa-to the Bahamas, in 1893, with :I party of twenty-three; to Barbados aiid Antigua, in 1918, with a party of nineteen; and t o the F i j i Islands and Kew Zealand, in 1922, with a party of six. His published ‘Narratives ” of these expeditions a r e exceedingly interesting. Professor Nutting’s research was devoted largely to marine zoology, and concerned particularly the hydroids and the Alcporiaria among the coelenterates. T o the taxonomy of these groups and to our knowledge of their distribution aiid relationships he made very valuable contributions. His publishcrl papers, if enumerated, would form n long list. Among these the most extensive a r e papers in the Proceedings of the United States National Museum on hydroids from Puget Sound and the north Pacific roast, on the Alcyonaria of the Californian roast, and 011 the Alcyonaria collected by the U. 8. S. Albatross, mainly in Japanese waters, in 1906. He published on the hydroids in t h e papers from the Harriman-Alaska Expedition, a n d on the Gorgonacea of the But his Dutch ‘siboga’ Expedition to the Dutch E a s t Indies in 1899-1900. most noteworthy publications a r e three large folio volumes oil American hydroids, published as special bulletins by the United States National Museuni in 1900, 1904, and 1915. H e had read the proof on a fortli-coming report on Philippine Iiyrlroids only a few days before his death. Professor Nutting was one of those wlio participated in the organization of the Central Branch of the Aincrican Society of Zoologists in 1902, and was its president in 1906. H e has heen ever active in his membership, and has contributed in many ways t o the work and t o the programs of the Society. As a man, he presented to those wlio came in contact with him a very attractive personality. Though hardly of medium height, his alert bearing, genial manner, and straightforward address carried a n appeal which on acquaintance ripened into affectionate regard. To his friends he gave much, and was ever eager t o impart more. His culture was broad, extending in many directions outside the limit of his chosen field, and in later years he prepared several papers of a more philosophic character. H e lived in fullest measure, and the impress of his life and character upon his friends, his university, and his science will long remain. ROBERTH. WOLCOTT, DAVIDD.

MISCELLANEOUS B U S I N E S S The Secretary reported the receipt of a statement of progress from Biological Abstracts. The report was not read, owing t o its length, but is given in full below. REPORTON I ( BIOLOGICAL ABSTRACTS” For thr infornwtion of tlte member societies of tlic U n i o n of American Biologzcal Societies “Biological Abstracts” was formally launched in December, 1926, and five numbers have been issued to date. That the journal is not yet on its regular monthly publication schedule is a matter of much regret t o the editors. This delay is not due t o any dearth of manuscript, but t o t h e deliberate policy t o proceed no more rapidly with publieation than adherence t o the standards and spirit of the undertaking permit. It is now certain, however, t h a t by the new year tho journal will attain its regular publication schedule. It is confidently helievcd that these temporary publication arrears will be more than compensated for by a steady adherence t o the standards set, and t o the plan of world-wide cooperation in the production of the journal. PR,OCEEDINGS 341 It is now reasonably clear that the estimates a s t o the proportions of the task, made by the Joint Publications Committee of the Union of American Biological Societies and the National Research Council, were sound. These were t o the effect that the literature in theoretical and applied biology, exclusive of clinical medicine, totaled approximately forty thousand titlrs annually; and that, with the typography and format adopted for the journal, it would require i n t h r vicinity of four thousand pages annually for thr abstracts and indexes. Also, the estimates as to printing costs are proving remarkably accurate. T t has taken time to assemble and train a conipetent scientific staff; there a r e practically no sources of trained personnel, since very little work of this character in biology has been done in America. Attention has been given to a proper balance b e t w e a the fields covered by the journal, and the present scientific staff is made up as follows: Animal biology, 1)r. Mary Jones Fisher, Dr. Ezra Allen, I h . Nellie Payne, Mr. Frank Haimbach; bacteriology, Dr. F. V. Rand; plant biology, Dr. Oran Raber, Dr. J. H. Schramm. This distribution is almost exactly proportional to the estimated annual volume of literature in the respective fieldsanimal biology, 20,000 papers ; bacteriology, 5000 ; plant biology, 10,000. The journal apparently has been favorably received, if one may judge from the flood of letters, many of them from leading biologists, that greeted i t s appearance. A favorable reception seems also to be indicated by the fact that, though only five issues are published, the subscription list is already nearly three thousand; of these, a few over one thousand are institutional subscriptions (the number *hich the Joint Committee estimated could be secured), the remaining being individual. The extent of subsrription support will not be apparent until the journal has maintained its regular schedule for some time and until at least one volume index is issued, the latter being the main consideration for the great body of taxonomic workers. Incidentally, the format, typography, paper, and general arrangement of the journal have met with very general approval. An encouraging beginning has been made in securing advertising. Contracts in hand for the first volume are sufficient t o cover the cost of business management, including salary of assistant, supplies, and circularizing, thus making all subscription income available for defraying printing costs of the abstracts and indexes. With growth in the subscription list, it is hoped that advertising can be made a substantial auxiliarj source of income and help to guarantee sufficient funds for necrssary printing. As soon as the journal reaches its regular publication schedule, it is very vital that the subscription list be very materially increased, as the printing outlay will necessarily be much greater with the larger number of issues per volume. I n the general editorial conduct of the journal the editors are adhering to the broadly cooperative and non-provincial spirit in which the undertaking was conceived. It requires more time t o get matters fully under way by these methods, but the conviction has steadily grown that it is the only sound method in a n undertaking of this character. It is a particular source of satisfaction to be able to report that the cooperation from biologists in nearly all parts of the world is hearty and beyond expectation. The degree to which the journal is already the product of a n almost world-wide cooperative effort will be apparent from a perusal of the names of the abstractors, representing as they do several thousand biologists and probably rvery country with biological activity. Besides 342 AMERICAN SOCIETY OF ZOOLOGISTS the thousands of biologists who cooperate by submitting abstracts of their own papers, the journal now has a regular staff of collaborators numbering approximately three thousand. The plan of operation, especially in the examination of the original publications, presupposed the establishment of cooperative relations with a number of iiistitutions with notable current library resources, in order t o avoid the prohibitive cost of subscribing t o the thousands of serials. These relations have been very satisfactorily established, and the editors are very greatly indebted t o the institutions that are so generously extending f acilities. Besides the University of Pennsylvania, the Philadelphia institutions which are extending especially important cooperation are the Academy of Natural Sciences of Philadelphia and the College of Physicians. At the former, about 2400 rurreiit serials (mainly in descriptive biology) are carefully perused, and at the latter about 1200. Including journals covered a t the central editorial office and elsewhere, about 4000 serials, in round numbers, are looked after in Philadelphia. This by no means includes all serials from which material must be gathered for “Biological Abstracts.” I f the library resources of Philadelphia may be said to be deficient in any direction, it is that of agriculture, since there is no local institution that is especially concerned with this field. The United States Department of Agriculture undoubtedly is the great center for literature in this field, and with the generous cooperation of the Department and Library authorities facilities have been extended enabling a member of the scientific staff of “Biological Abstracts ” t o consult such publications in the Department of Agriculture Library and elsewhere in Washington as are not available in Philadelphia. Similar cooperation has likewise been generously extended by the SurgeonGeneral’s Library, Library of Congress, Smithsonian Institution, and others. The total number of journals now being regularly perused is about 5000. The number requiring attention will probably reach 6000, if not more. To date, over 30,000 abstracts have been received and some thousands are in process of preparation. After receiving the abstracts, follows one of the largest tasks-the detailed indexing-all of which is completed before publication. Only about 8500 abstracts have been published t o date, but with the establishment of the regular monthly publication schedule the arrears in publication will be eliminated as rapidly as possible, so that the incoming abstracts may be published with only the unavoidable delay incident to indexing, editing, and printing. Thus the apparent incompleteness of the journal, judged by the numbers published t o date, is due to delay in publishing abstracts rather than t o incompleteness in examining the original publications. The editors adopted the policy of inviting collaboration in the abstracting on a non-honorarium basis. This policy presupposes a large and diversified number of collaborators in order that only a small and uon-burdensome contribution may be asked from any one, and that the papers to be abstracted may be reasonably closely adapted to the collaborators interests. While there are certain special fields and a few languages in which the staff of collaborators, now about 3000, is not yet adequate, it is reasonably so for the great bulk of the literature, and is, it is believed, an unusual demonstration of cooperation. The staff of collaborators is steadily being amplified. This willingness of so large a number of biologists to give time and effort without monetary compensation to produce an ’ PROCEEDINGS 343 adequate abstracting service in biology is perhaps the best evidence of the importance attached by biologists t o the undertaking. The Union desires to keep the subscription price of the journal within reasonable reach of individual biologists, even those in the earlier stages of their development. To pay honoraria, even very inadequate ones, would very materially increase the subscription price. The subscription price of the journal was placed a t $15.00 per annual volume. To individual biologists, however, a discount of 40 per cent is made in view of the contribution of abstracts by thousands of biologists throughout the world on a non-honorarium basis; thus the cost of the annual volume is $9.00 to individual biologists. I f these prices can be maintained, they will be remarkably low for a service of this kind, lower by f a r than those of many existing services covering a much smaller field; the prices, it is believed, are within reach of the majority of inrlividual biologists and institutions, thus making the journal vastly more effective than would be the case if the subscription price were such that in the main the journal could be made available only in some libraries. The most obvious service the journal renders is in providing abstracts and indexes so arranged as to serve the needs of specialists. Not so apparent, but perhaps equally important, is the synthetic influence which the journal is certain t o exercise, since it will eventually make available in one journal a master key, with abstracts and detailed indexes (author, subject, and systematic) of practically the entire biological literature. Very important in the judgment of the editors is the fact that abstracts of theoretical and applied research have been kept within the same journal. While only a good beginning has been made, the editors are increasingly confident that, with adequate funds from subscriptions to guarantee publication of abstracts and indexes, the undertaking can be carried through on a high plane and on the broadly cooperative basis originally planned. To this end, it is hoped that biologists individually will feel justified in continuing their support through personal subscriptions. THE EDITORS. The Secretary read the following excerpts of a letter from Doctor Greenman, of The Wistar Institute : The chief point which I wish t o report t o the Society is that The Wistar Institute is now installing its own engraving plant for the production of the highest type of illustrations for scientific papers. We shall specialize in heliotypes and the first journal to benefit by this improvement will be the Journal of Morphology and Physiology. While we are unable t o use heliotypes for all illustrations, they will be used in those instanres where no other type of illustration will give as good results. I wish also t o report t o your Society that the Bibliographic Service of The Wistar Institute is extending its cooperation t o other journals not published by the Institute. The latest journal for which this service is t o function is the newly established Journal of Physiological Zoology. We have already taken on two foreign journals, and requests have been received t o consider this service for 344 AMERICAN SOCIETY OF ZOOLOGISTS othcr foreign journals. It is a serious proposition t o thus extend the Bibliographic Service, and any expression the American Society of Zoologists desires t o make regarding the advisability of such extension will be most gratefully receivrd by The Wistar Tnstitute. The Secretary was instructed to thank Doctor Greenman on behalf of the Society for, the improvement in the facilities of The Wistar Institute for reproduction of illustrations. The Secretary was also instructed to inquire what the relation might be between the Abstract Service of The Wistar Institute and Biological Abstracts. The Chairman was instructed to appoint a committee of two with power to draw up appropriate resolutions of thanks in connection with entertainment of the Society in Nashville. The Committee, consisting of W. C. Allee, H. F. Perkins. and D. E. Minnich, drew up the following resolutions : 1. That the Society, through its Secretary, express t o Dr. R. S. Cunningham and his associates in t h e Department of Anatomy and t o Dr. W. S. Leathers, Associate Dean of the Medical School, its appreciation of their hospitality extended the Society in making available the laboratories and lecture rooms of the Vanderbilt School of Medicine for this meeting. 8. That the Society, through its Secretary, express t o the Local Committee, consisting of E. E. Reinke, F. H. Swett, and W. McA. Deacon, the Society’s appreciation of its highly e s c i e n t work in connection with the local arrangoments f o r this meeting. The Secretary gave a brief summary of the results t o date of the questionnaire on the time of meeting. An informal discussion followed. The meeting was then adjourned. D. E.
