POLY TECHNIC INSTITUTION.
The professor of chemistry, Mr. J. H. Pepper, or
menced here on Monday a most, popular subject fori
Englishmen, viz.—Ale-brewing, and the alleged
aduteration of the justly famed and favourite, bitter ale
Messrs. Salt and Co., and other Burton brewerEt
which the learned gentlemen had paid especial visits, SD._
was, therefore, able to speak as an eye-witness a 0°
perfect integrity of the operations conducted in ten
establishments. The, lecturer commenced with a revie
of the process of fermentation, which might aptly .be
termed one of transmutation, and illustrated by to
atructive diagrams and lucid explemation that the starca,
in the barley was converted partly by the first proces9 of
malting into sugar, and a curious principle canto:oloC
nitrogen, called diastase. This curious agent converts
the rest of the starch in the operation of reasbing.lnto
grape sugar, which, fermented by yeast (another nitro-
genous compound), was convertd into alcohol. The
starch and the sugar contain the same quantity
carbon with variable quantities of oxygen and hydrogen
in the proportions to lona water, so that the shirt O
one's back may be turned chemically into alcohol (vu/yo,
gin) without that common mode of appealing to the
pawnbroker first; because linen is Helaine, this can be
converted into grape sugar by boiling with sulphur°
acid, and the grape sugar may be fermented into alcohol.
He omitted to mention the addition of hops after the
mashing, which afford the well-known grateful and aro-
matic bitter, perfectly unlike and superior to any other
principle of the same nature. Afie'r the lecturer. had
spoken with the highest encomium of the cleanliness,
order, regularity, and magnitude, of the brewery opera-
tions conducted in Burton-on-Trent, he alluded in the
last place to the detection of strychnine, which was proved
