    ONLY a few changes have been made in the text of the last edition. Of these, those most worthy of mention are (1) the incorporation of Prof. Jennings’ most interesting observations on the motion of Amoeba, which has involved the discarding of Prof. Rhumbler’s hypothesis which was adopted in the third edition; (2) the inclusion of some new and interesting results on the physiology of the bivalve Mollusca; (3) the adoption of Dr Ridewood’s results on the development of centra, which have narrowed the gap between the so-called arco-centra and chorda- centra; and (4) the rewriting of the section dealing with Human races in accordance with the views of Ripley, Elliot-Smith, Keith and other modern Anthropologists. A. E. S. E. W. M. I wish to state that owing to pressure of duties as Vice- Chancellor, and other claims on my time, the Fourth Edition has been revised and seen through the Press by Prof. MacBride, and any improvements that appear in it are solely due to him.
