In is brief compendium of Zoology is designed for use 

 in gram mar and high schools. It is introductory to the 

 author's larger Zoology. Though partly rewritten, and 

 with additions regarding the habits of hirds and mammal-, 

 portions of the larger book have been retained, the more 

 difficult parts being omitted so as to adapt it for younger 

 pupils, or those whose time is limited. 



No class in the study of Zoology should depend on a 

 book alone, but specimens should be in constant use, — the 

 text-hook being rather for reference, — as all school work 

 in Zoology should be object- teaching. Before taking up 

 the book, each member of the class should be required to 

 examine a fish — a perch, dinner, smelt, or any common 

 fish; the pupil should then draw it with all the fins ex- 

 panded; then with the aid of the direction- on pages l"'l 

 to 157, by means of a small scalpel, forceps, and Bcissors, 

 the student should dissect the fish, drawing the heart. 

 Stomach, etc., and a transverse section; a preparation of 

 the brain can be easily made with the aid of a com- 

 petent teacher. Saving thus obtained some notion of the 

 structure of a common vertebrate animal as a I 

 of comparison, the class can begin to study the book: 

 meanwhile once or twice a week, if not oftener. taking a 

 laboratory lesson, drawing and dissecting a star-fish, clam.
