A text-book in which physiology is correlated with 

 morphology by describing the most important structural 

 features of the various types of animals and by also point- 

 ing out the vital phenomena as expressed in the functions 

 of the organs. Every phylum in the animal kingdom is 

 introduced by an account of the anatomy, physiology, 

 ecology and economic importance of one or more types. 

 Furthermore, the animals in each phylum are compared 

 with those of nearly related phyla so as to afford the 

 student a realization of the unity as well as of the variety 

 in animal life, and the types selected are common native 

 species which can be obtained for direct observation in 

 the laboratory. 



The work is progressive and up to date, even such recent 

 topics as the work on the hookworm in the United States 

 being considered.
