Cell Motility and the Cytoskeleton 42:82 (1999) ERRATUM Cell Motility and the Cytoskeleton 32:90–94 (1995) Landmarks in Cilia Research From Leeuwenhoek to Us Peter Satir Department of Anatomy and Structural Biology Albert Einstein College of Medicine, Bronx, New York Correction: It has come to my attention that the article by Hausmann and Radek , quoted in my article [Satir, 1995] as demonstrating axonemes that run clockwise in one row, but counter-clockwise in an adjacent row in a termite gut protozoan, is incorrect. The images shown in the Hausmann and Radek  article were computer generated. The single enantiomorphic form of the axoneme, with arms running clockwise when the axoneme is viewed base to tip, remains inviolate.
