PRODUCTS OF VEGETABLE ANALYSIS. 



OF the products of vegetable analysis as obtained 

 by the foregoing processes, some consist of several 

 heterogeneous substances, and are consequently 

 compound, as being capable of further decomposi- 

 tion ; and some consist of one individual substance 

 only, and are consequently simple, as being incapa- 

 ble of further decomposition. Hence the ground 

 of a subordinate division that shall form the subject 

 of the two following chapters ; Compound Pro- 

 ducts and Simple Products. 



CHAPTER I. 



COMPOUND PRODUCTS. 



/ 



THE compound products of analysis are so very Principle 

 numerous in themselves, or so much diversified in a 



their qualities, as to render it necessary to adopt ment 

 some definite and specific plan of arrangement in 

 order to give method and precision to the subject ; 

 and accordingly different writers have adopted dif-
