ILLUSTRATED

There is no other book just like this. Not only does it give the salient facts of structural zoology and the development of the various branches of animals, but also the natural history - the life and habits - thus showing the interrelations of structure, habit, and environment. In a word, it gives the principles of zoology and their actual application. The economic phase is emphasized. Part I - the Field and Laboratory Guide - is designed for practical instruction in the field and laboratory. To enhance its value for this purpose blank pages are inserted for notes.

A Laboratory Manual of Invertebrate Zoology. By Gilman A. Drew, Ph.D., Assistant Director at Marine Biological Laboratory, Woods Hole, Mass. With the aid of Former and Present Members of the Zoological Staff of Instructors. 12mo of 213 pages. July, 1913 Cloth, $ 1.25 net.

SECOND EDITION

The subject is presented in a logical way, and the type method of study has been followed, as this method has been the prevailing one for many years.

Prof. Allison A. Smyth, Jr., Virginia Polytechnic Institute.

" I think it is the best laboratory manual of zoology I have yet seen. The large number of forms dealt with makes the work applicable to almost any locality".
