344 Mr. W. Brandt's Experiments to ascertain 
hours ; its specific gravity (at the temperature of 6o° Fahren- 
heit), was then very carefully ascertained, by weighing it in 
a bottle holding exactly one thousand grains of distilled water 
at the above temperature, and the proportion of alcohol per 
cent, by measure , was estimated by a reference to Mr. Gilpin's 
tables,* the specific gravity of the standard alcohol being 
0,82300 at 6o°. 
As the most convenient mode of exhibiting the results of 
these numerous experiments, I have thrown them into the 
form of a table ; in the first column the wine is specified ; the 
second contains its specific gravity after distillation, as above 
described ; and the third exhibits the proportion of the pure 
spirit, which every hundred parts of the wine contain. I have 
also inserted porter, ale, cyder, ■f brandy, and some other 
spirituous liquors, for the convenience of comparing their 
strength, with that of the wines.

f The proportion of spirit, which may be obtained from these three liquors, is 
subject to considerable variation in different samples : the number given for each, 
in the table, is therefore the mean of several experiments, as it did not seem necessary 
to specify them separately.
