464 On the Process of making Spirits in [Dec. 



as a prescriptive charge upon the distiller. But the mat- 

 ter will appear more obvious, by giving' a brief explanation 

 of the principles on which the theory is founded : viz., that 

 by the saccharometer can be inferred the quantity of sac- 

 charine matter contained in worts of any specific gravity, 

 and that every pound weight of such matter decomposed by 

 fermentation, produces -905 parts of a pound of proof spirits 

 at the specific gravity of 920, water being 1000 at the tem- 

 perature of 60. 



To give an example, suppose 100 gallons of worts were 

 made at the specific gravity of 1*060, and attenuated by fer- 

 mentation of the sp. gr. of 1*001. Here, however, it may 

 be necessary to notice, that the one degree, which is called 

 the lowest attenuated gravity, is not the real gravity of the 

 wash were it deprived of the spirits contained therein, it 

 must first be boiled till all the spirits are dissipated, and 

 pure water added to make up the original bulk, and it will 

 then be found, that instead of 1*001, the specific gravity 

 will have become 1*011, (the difference which is 10, is due 

 to the operation of the spirits in the wash before boiling). 



Having thus explained, we find from the tables before 

 adverted to, that 100 gallons worts at the gravity of 1*060 

 contain, 



155*2 lbs. saccharine.
