and as every gallon of spirits of the specific

gravity of 0·909 contains 4·6 pounds of such

alcohol, it will take twice 4·6, or 9·2 pounds of

saccharine matter to produce the said gallon.

To these 9·2 pounds, truly transmuted in the

process, we must add one-fifth, or

·84 pounds,

which will raise to

·04 the amount of solid

matter employed in producing a gallon of the

above spirits.

2. As the imperfect saccharine infusion ob–

tained from raw grain is much more acescent

than the rich sugary solution got from malt in

the breweries, the distiller must use every pre–

caution to cool his worts as quickly as possible,

and to keep them clear from any acetous taint.

As the worts cool, a quantity of starchy 1natter

is precipitated, but it is all carefully swept along

into the fermenting tun, and undoubtedly con–

tributes to increase the production of alcohol.

During the winter and temperate inonths, when

the distilleries are most actively at work, the

temperature at which the worts are set is usu-
