vi ANIMAL STUDIES 



the purpose of Plant Studies are entirely applicable to Ani- 

 mal Studies as well : 



"The book is intended to serve as a supplement to 

 three important factors : 



" (1) The teacher, who must amplify and suggest 

 at every point; (2) the laboratory, which must bring 

 the pupil face to face with plants and their structures; 

 (3) field-work, which must relate the facts observed in the 

 laboratory to their actual place in Nature, and must bring 

 new facts to notice which can be observed nowhere else." 



Jordan and Price's Animal Structures, a Laboratory 

 Manual of Zoology, will be found eminently useful in con- 

 nection with the reading and study of this text.
