820 SUBSTANCES FOUND TO POSSESS 





Acetic and butyric ether may be formed, therefore, 

 independent of cenanthic ether, and this may serve 

 to be resolved, in course of time, into other ethers of 

 the fatty acids. 



Here we must make a distinction. When cenanthic 

 ether is resolved into another fatty acid, more oxide of 

 ethyl is necessary to saturate this acid if the fatty acid 

 which is hereby originated has a lower atomic weight, 

 and less if it possess a greater atomic weight. Less, 

 therefore, if, for example, capric acid (C 20 H 20 O 4 ), more 

 if caproic acid (C 12 H 12 O 4 ), or butyric acid (C 8 H 8 O 4 ), 

 are formed out of cenanthic acid (C 14 H 14 O 3 ), or 

 pelargonic acid (C 18 H 18 O 4 ). 



Some tartaric acid always, however, remains in 

 wine, and by its power of etherising, it strengthens 

 every acid that forms in wine. The formation of oxide 

 of ethyl in wine presents no difficulty. 



The question is, how do the fatty acids arise from 

 oananthic or pelargonic acid ? 



We will give a sketch of both.
