I ZOOLOGY 



I By T. D. A. COCKERELL 



I Professor of Zoology y Uni'versity of Colorado 



I Zoology for the average individual who will not specialize in the subject 



I should not be too rich in detailed facts of structure and classification. = 



i Experience shows that much minutiae are not remembered, and do not | 



I necessarily leave as a residue any broad and useful conceptions. | 



1 Zoology, a Textbook for Colleges and Universities, by Professor Cocker- | 



I ell, is based on these views. The book grew out of a course that was de- | 



i veioped in actual and successful teaching experience. It is calculated | 



i to convey to students a point of view that will be of social value. |

I The first chapter is entitled The Physical Universe, and it considers the 



I fundamental ideas of physical science , taking nothing for granted . The 



I treatment of the animal kingdom is at once broad and systematic. 



I The great phyla and some of the sub-groups are discussed from the 



I structural angle. More space than usual is given to a description of 



i animals. The geographic origin and the migrations of the world's fauna 



I are ably considered. The Florissant Shales of Colorado and the sub- 



1 jects of genetics and entomology are treated with unusual authority. 



I The topics throughout are developed in a way that makes delightful 



i as well as highly instructive reading. The volume is illustrated from 



I photographs, many of which were selected from hundreds that were 



1 taken at the New York Zoological Garden. It contains numerous 



I drawings that were made under the direction of the author, expressly 



I to illustrate his text. While Cockerell's Zoology is primarily designed 



I for use in classes that are now being taught zoology, it presents ideas 



I that make it available for use in a course in general biology. It is a 



I workable text of college grade. 



I An important critic has pronounced it the "first zoology since Huxley 



I written in good English." 



I Illustrated with maps, charts, drawings, and photographs. 



I Cloth xii +558 pages. Price ^SM.
