48 Researches on Wines and other Fermented Liquors. 
This process, it will be observed, is essentially that of Mr. Brande, 
and that my results may be easily compared with his, I have re- 
ferred them, to the same standard, which he adopted. I may also 
state, that | compared these results, in one or two cases, with those 
produced by the process of precipitation, by subacetate of lead, and 
subsequent separation of the alcohol by subcarbonate of potassa. 
They were found to be so nearly coincident, that I did not think it 
worth while, to extend this mode of investigation.

The results in the above table agree generally with those of Mr. 
Brande. In all cases where the difference was marked, as in Nos. 
13, 14, 22, 23 and 24, the trials were repeated several times, and 
* It is proper to state, that this investigation was commenced at the request of 
E. C. Delavan, Esq., whose philanthropic exertions in the cause of temperance, 
are so well known, and so justly appreciated. Fyrom him and from other gentle- 
men, in the City of Albany, I received, with a few exceptions, all the specimens 
of wines and other liquors, which | examined. At my suggestion, each specimen 
was accompanied with a label, containing a notice of its reputed age and charac- 
ter; of which, I have introduced only so much in this table, as was necessary to 
identify and distinguish it. 1 should observe, that most of the wines are said to 
be among the purest and best, which are brought to this country.
