Biology and Zoology 



DODGE'S INTRODUCTION TO ELEMENTARY PRACTICAL 

 BIOLOGY 



A Laboratory Guide for High School and College Students. 

 By Charles Wright Dodge, M.S., Professor of Biology 



in the University of Rochester $1.80 



This is a manual for laboratory work rather than a 

 text-book of instruction. It is intended to develop in the 

 student the power of independent investigation and to 

 teach him to observe correctly, to draw proper conclusions 

 from the facts observed," to express in writing or by means 

 of drawings the results obtained. The work consists 

 essentially of a series of questions and experiments on 

 the structure and physiology of common animals and 

 plants typical of their kind — questions which can be 

 answered only by actual investigation or by experiment. 

 Directions are given for the collection of specimens, for 

 their preservation, and for preparing them for examination; 

 also for performing simple physiological experiments. 



ORTON'S COMPARATIVE ZOOLOGY, STRUCTURAL AND 

 SYSTEMATIC 



By James Orton, A.M., Ph.D., late Professor of Natural 

 History in Vassar College. New Edition revised by 

 Charles Wright Dodge, M.S., Professor of Biology in 



the University of Rochester $1.80 



This work is designed primarily as a manual of 

 instruction for use in higher schools and colleges. It 

 aims to present clearly the latest established facts and 

 principles of the science. Its distinctive character con- 

 sists in the treatment of the whole animal kingdom as a 

 unit and in the comparative study of the development and 

 variations of the different species, their organs, functions, 

 etc. The book has been thoroughly revised in the light 

 of the most recent phases of the science, and adapted to 

 the laboratory as well as to the literary method of teaching.
