300 SUBSTANCES FOUND TO POSSESS 



GEnanthic ether is prepared in large quantities by 

 mixing the sediment of the wine with water, and then 

 distilling it. A weak spirit is thus procured, which 

 is re-distilled, and towards the end of the distillation 

 the cenanthic ether is obtained. 



As, however, the first raw spirit never yields more 

 than TWQO of this ether, it has been calculated that 

 not more than 4oio6 is contained in the wine. A 

 large proportion of oenanthic acid is contained in the 

 ether which is first obtained. 



(Enanthic ether is procured in the same manner 

 during the preparation of moutwyn. It flows at last 

 from the first destillate, and can thus be collected. It 

 is, therefore, not an ingredient of the grape, but a 

 product of fermentation. 



Before speaking more particularly of cenanthie 

 ether, I will enumerate shortly 



THE ODORIFEROUS SUBSTANCES DEVELOPED IN WINE 

 IN THE COURSE OF TIME. 



Besides the substances already named, the following 

 may be reckoned among those which impart aroma to 

 wine, which are originated in it by fermentation, and 

 are either found, or may be presumed to exist in 

 wine. They do* not all exist in every wine, but one 

 or several are found combined with osnanthic ether 

 in aromatic wines. They are compounds of oxide of
