This new text-book on Zoölogy is intended for classes in High Schools, Academies, and other Secondary Schools. While sufficiently elementary for beginners in the study it is full and comprehensive enough for students pursuing a regular course in the Natural Sciences. It has been prepared by a practical teacher, and is the direct result of school-room experience, field observation and laboratory practice. The design of the book is to give a good general knowledge of the subject of Zoölogy, to cultivate an interest in nature study, and to encourage the pupil to observe and to compare for himself and then to arrange and classify his knowledge. Only typical or principal forms are described, and in their description only such technical terms are used as are necessary, and these are carefully defined. Each subject is fully illustrated, the illustrations being selected and arranged to aid the pupil in understanding the structure of each form. _Copies of Burnet's School Zoölogy will be sent prepaid to any address, on receipt of the price, by the Publishers_: American Book Company New York ◆ Cincinnati ◆ Chicago Birds of the United States A Manual for the Identification of Species East of the Rocky Mountains By AUSTIN C. APGAR Author of "Trees of the Northern United States," etc. Cloth, 12mo, 415 pages, with numerous illustrations. Price, $2.00 The object of this book is to encourage the study of Birds by making it a pleasant and easy task. The treatment, while thoroughly scientific and accurate, is interesting and popular in form and attractive to the reader or student. It covers the following divisions and subjects: PART I. A general description of Birds and an explanation of the technical terms used by ornithologists. PART II. Classification and description of each species with Key. PART III. The study of Birds in the field, with Key for their identification. PART IV. Preparation of Bird specimens. The descriptions of the several species have been prepared with great care and present several advantages over those in other books. They are short and so expressed that they may be recalled readily while looking at the bird. They are thus especially adapted for field use. The illustrations were drawn especially for this work. Their number, scientific accuracy, and careful execution add much to the value and interest of the book. The general Key to Land and Water Birds and a very full index make the book convenient and serviceable both for the study and for field work. _Apgar's Birds of the United States will be sent, prepaid, to any address on receipt of the price by the Publishers_: American Book Company NEW YORK ◆ CINCINNATI ◆ CHICAGO Baldwin's School Readers By JAMES BALDWIN Editor of "Harper's Readers," Author of "Old Greek Stories," "Old Stories of the East," etc.
