More than a sketch it could not be in the space at the author's command; but he has so skilfully selected his examples to illustrate both the natural groups and the faunas which they represent, that his work forms a most commendable ground-plan for the study of natural history. Few writers have been so successful in handling this subject. His style is singularly attractive to the young readers whom he has in view; yet he does not depart from accuracy, nor exaggerate with false emphasis some unusual phase of an animal's character, which is the fault of many who try to "popularize" zoölogy. One may feel confident, therefore, that the boy or girl who opens this volume will enjoy it and profit by it. The sketch dwells on the animals most often to be seen in nature, or in menageries, or read of in books of travel and adventure, and will thus serve as a valuable reference aid in such reading. But it will, and ought to, do more. It will arouse anew that interest in the creatures about us which is as natural as breath to every youngster, but is too rarely fostered by parents and teachers.
