DISTILLATION. 163 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 l ·84 pounds, which will raise to 11 ·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-
