Mr Forster Takes Particular Notice Of What Is
Mentioned In The Text About The Fermentation Of The Inspissated Juice
Of
Malt, or, as he calls it, essence of beer; and he says, that, by
the advice of his father, a
Vessel strongly fumigated with sulphur was
filled with it, and prevented the fermentation for a few days. He does
not explain on what principle, and perhaps was not acquainted with it.
The fact is, that sulphuric acid, which is produced by the burning of
sulphur, has the power of checking, or altogether destroying, the
fermentation of substances. In the present case, it seems, enough of
it had not been produced to answer the purpose effectually. Some other
acids have the same power. Hence the desideratum mentioned in the text
is easily supplied. The juice, it may be thought, will be changed by
the addition of a strong acid, and rendered unserviceable. There can
be no doubt, however, that when it is required for the purpose of
making beer, &c. means could be used to neutralize the acid that had
been added to it, without materially, or at all, affecting the juice
itself. - E.
[4] "When we made application to this indolent Don, by the governor's
direction, to be supplied with cattle, he indeed promised to furnish
us with as many as we wanted, but we never got more than a single lean
bullock. The company perfectly tyrannizes over the inhabitants, and
sells them wretched merchandize at exorbitant prices." - G.F.
