only a limited and narrow view of the science of chem- 

 istry. 



In the study of the " Chemistry of Plant and Animal 

 I,ife,' r it is the aim to bring the student into close contact 

 with nature which is one of the requisites for perfect agri- 

 culture. Although not all of the laws relating to the chem- 

 istry of plant and animal life have been discovered, many 

 of those relating to soils and foods, particularly human 

 foods, are known and can be applied to every-day life 

 affairs.
