ESSENTIALS OF BIOLOGY 



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



Department of Biology, De Witt Clinton High School, 

 New York City. 



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. 



SHARPE'S LABORATORY 

 MANUAL IN BIOLOGY 



IN this Manual the 56 important problems of Hunter's 

 Essentials of Biology are solved ; that is, the principles of 

 biology are developed from the laboratory standpoint. It is 

 a teacher's detailed directions put into print. It states the prob- 

 lems, and then tells what materials and apparatus are necessary 

 and how they are to be used, how to avoid mistakes, and how 

 to get at the facts when they are found. Following each prob- 

 lem and its solution is a full list of references to other books.
