D.Joesten writes that this monograph should contain a high percentage of papers on hydrogen bonds that have appeared since Pimentel and McClellan’s book (The Hydrogen Bond. Freeman, San Franciscp 1960). In fact the book contains almost 3000 references, and half of it is taken up by indexes and tables. Most of the English-language literature from 1960 to 1973 inclusive is handled, but that in foreign languages (German, French, Japanese, Russian, etc.) is almost ignored. Nevertheless, this is an invaluable bibliography. Particularly praiseworthy is the clear presentation of the thermodynamic results (40pages), while the collection “correlations” (of, e.g. spectral shifts in the IR and NMR spectra) occupies only 60 pages. Almost half of the actua’l text is taken u p by a chapter on the theory of hydrogen bond formation, written by L. J . Schaad; this includes a very useful introduction to the quantum-chemical methods used, but unfortunately there is no list of contents for this section of more than 100 pages. The price, 45 dollars, seems rather high for a book that is not printed by classical methods but produced photomechanically.

The second, expanded and improved edition of this notable book is now available. The fact that a new edition is required after only two years from first going to print shows that the book has found a large circle of interested readers. In the review of the first editionr” it was noted that in many places the text went beyond what would be required for their normal study by chemists interested mainly in preparative or analytical work. and that some very elementary mathematical laws were mentioned only in passing. This choice of material is, however, by no means regrettable, since there are sufficient mathematical texts for chemists dealing with very much simpler problems. While there is little point in repeating the table of contents, it should be noted that new chapters on n-dimensional vector space and on reciprocal space have been introduced in the section on vector calculations. In addition, the sections on the solution of differential equations and on group theory have been considerably expanded, so that in its present form the book differs considerably from the first edition. The libraries of Institutes and Seminars are recommended to obtain this, again excellently produced, volume. Although the author has taken great trouble to remove misprints there remains, as usual, an unavoidable residue of errors that should be corrected in the next edition which will certainly soon be required. In this connection the following may be noted: on the left-hand side of eq. (2) on p. 132 the square of the vector magnitude would be better written in the form (a)’. In Table 1 on p. 220 the range of the definition is sometimes (cf. e. g. the first derivations of tanx, cot x, sin- x, and cos- x) not provided with the necessary additional limitations, i. e. the polar positions are not excluded. O n p. 290, line 1 should read “n - 2 and m = 3”. The last term of the Wronski determinant [eq. (109)] on p. 475 is wrong. Correspondingly, in the text (penultimate line of the first sentence), "yen)" should be replaced by “y‘”- ‘I”. ’ Angew. Chem. internat. Edit. 1 Vol. 14 ( 1 9 7 5 ) 1 No. 9 It is to be hoped that Zachmann’s book will find a place in research and teaching that corresponds to its real value. Perhaps at a suitable time this book can be made accessible to a large circle of students by means of a cheaper paperback edition. Theodor Ackermann [NB 266 IE] [l] Cf. Angew. Chem. 85, 835 (1973); Angew. Chem. internat. Edit. 12, 866 (1973). Programmierte Prufung. Chemie, Physik, Physikalische Chemie (Programmed Learning. Chemistry, Physics, and Physical Chemistry). By W Klein and H . Mayer, Verlag Chemie, GmbH, Weinheim 1974. 1st Edit., 376 pages, paperback, D M 16.80. Problems with several possible answers d o not comprise all that can be acquired from teaching, yet they are popular because the results can be simply evaluated. In their book Klein and Mayer set out test exercises in the fields of general inorganic, organic, and physical chemistry, physics, and laboratory techniques that can be used in the training of chemistry laboratory technicians. By working through this book one can evaluate his own knowledge, since the number of points that he has accumulated fits into a scheme set up for the results of the test. On looking carefully through the test exercises one is struck by how hard it is to find useful problems and several answers. Careless formulation leads so easily to errors. It should not be stated that atoms are the smallest particles of an element that show all the properties of the element (p. 15, problem 2), since where d o single atoms have the properties of the element? Similar doubt attaches to the statement (p. 128, problem 59): Compounds with one asymmetric C atom rotate the plane of polarized light. Mesotartaric acid actually contains two asymmetric C atoms but is nevertheless optically inactive. The concept of a mole is nowadays defined differently (p. 16, problem 4), and the concept of a gram-atom is no longer used (p. 17, problem 8). Since oxidation number is defined, oxidation and reduction reactions should bedescribed with its use. Not all reactions with hydrogen are reductions according to the expanded definition (p. 26, problem 36), e . g . lithium is oxidized on reaction with hydrogen. The authors should think again about the formulations of many of the test exercises and their answers, perhaps even set them u p again in relation to a modern curriculum. In spite of some limitations, multiple-choice exercises such as the ones in this “Programmed Learning” are a great help in teaching, and it would thus be very welcome if the authors would further develop their test program.

Volume 4 appeared at the end of 1974, beginning with p and ending with pK value; it contains about 100 pages more than the comparable part of the sixth edition. This expansion is due to the inclusion of new key-words, e.g. from the field of medicine (parkinsonism, paradontosis, gastric 651
