The authors are well known as clear and precise exponents of their subject. In his text-book they have produced an introduction both to general zoology as well as to that specific phase of it called “economic.”

The first chapters introduce the reader to general facts of animal structure and life and are arranged on the basis of accepted pedagogic principles. The latter chapters, arranged on a basis of animal classification proceeding from the samples to the nine highly developed groups, include not only general facts pertaining to the groups treated, but introduce and give general attention to the economic relations of the various members of the groups. Finally, there is presented a form of encyclopædic treatment of a wide range of facts wholly economic in aspect.
