ORGANIC CHEMISTRY 



APPLIED TO 



PART I. 



OF THE CHEMICAL PROCESSES IN THE NUTRITION OF 

 VEGETABLES. 



THE object of organic chemistry is to discover 

 the chemical conditions which are essential to the 

 life and perfect development of animals and vege- 

 tables, and, generally, to investigate all those pro- 

 cesses of organic nature which are due to the 

 operation of chemical laws. 



The continued existence of all living beings is 

 dependent on the reception by them of certain 

 substances, which are applied to the nutrition of 

 their frame. An inquiry, therefore, into the condi- 

 tions on which the life and growth of living beings 

 depend, involves the study of those substances 

 which serve them as nutriment, as well as the 

 investigation of the sources whence these sub- 

 stances are derived, and the changes which they 

 undergo in the process of assimilation.
