ESSENTIALS OE BIOLOGY 



By GEORGE WILLIAM HUNTER, A. M., Head of 



Department of Biology, De Witt Clinton High School, 



New York City. tf 



#1.25 



THIS new first-year course treats the subject of biology 

 as a whole, and meets the requirements of the leading 

 colleges and associations of science teachers. Instead 

 of discussing plants, animals, and man as separate forms of 

 living organisms, it treats of life in a comprehensive manner, 

 and particularly in its relations to the progress of humanity. 

 Each main topic is introduced by a problem, which the pupil 

 is to solve by actual laboratory work. The text that follows 

 explains and illustrates the meaning of each problem. The 

 work throughout aims to have a human interest and a practical 

 value, and to provide the simplest and most easily compre- 

 hended method of demonstration. At the end of each chap- 

 ter are lists of references to both elementary and advanced 

 books for collateral reading.
