Profusely illustrated with drawings, diagrams and tables, well organized and attractive in printing and make-up, this is an excellent textbook and at the same time a fine elementary reference book on zoology. It bases its discussion on the anatomy of the rat but clearly and interestingly makes reference to numerous other animals, placing them in a correct position in the animal kingdom in such a way that the merest novice can understand. The chapter on embryology, with its chart illustrating fertilization, germ cell formation, cleavage, germ layer formation, segmentation, morphogenesis and growth, is exceptionally good, as is also the chapter on philosophical zoology and organic evolution. The history of zoology gives a useful background and might conceivably have been of greater service to the student or reader if it had been placed first instead of last. There is a good index and the summaries at the head of each chapter
