pp. 319-350. An extract bound in new cloth, a very good copy. *AGAR [1882-1951], zoologist, educated at Sedbergh School and King's College Cambridge, where Bateson was an inspiration to him in studying genetics. His first position was in the Zoology Department in Glasgow and his main interest there was in the embryology of the lungfishes Lepidosiren and Protopterus. His meticulous study in this area and subsequently his investigation of parthenogenetic crustacea, led to his conclusion that Mendelian laws could be explained in terms of chromosome segregation. In 1919 he was appointed to the chair of zoology at the University of Melbourne. His longstanding interest in genetics and particularly Lamarckian inheritance was reflected in his introducing the study of cytology and genetics and particularly the investigation of marsupial chromosomes into the university curriculum. A central feature of his own research was the reworking of William McDougall's experiments on the inheritance of learning in rats. He had long been opposed to the theory of inheritance of acquired characters and his repetition of McDougall's work over twenty years was one of the most important refutations of previously influential Lamarckian theory.…
