erated molasses.

If we estimate the superfluous carbonic acid gas of this quantity of
materials at only twenty-eight pounds per hundred, that will be sixteen
hundred and eighty pounds dissipated during the fermentation, which is
a loss, on every brewing of this quantity of materials, of upwards of
forty-one gallons of spirit, of the strength of one to ten.

What is computed here in spirit, may easily be applied to wine, porter,
beer, ale, sweets, &c. In barrels allowing three gallons and three
quarts of spirit per barrel to the former, and four gallons per barrel
to the latter, which gives eleven barrels and three quarters of the
one, and ten barrels and a quarter of the other, lost on each brewing
of eighty quarters of malt, or the average of that quantity of other
materials, by the mismanagement of the fermentation in one point only.

It must appear evident to every person capable of investigating this
calculation, that every six or seven pounds of carbon, fixed upon each
quarter of malt, or other materials, there will be an augmentation of
gravity or strength on this number of quarters, of ten or twelve
barrels each brewing; that is, every six or seven pounds of this
fugitive carbon that we arrest and fix in the fermenting fluid, as a
component part of the subsequent produce, by presenting the requisite
portion of oxygen and hydrogen, for the purpose within the sphere of
each others attraction, we increase our strength in the before-mentioned
_ratio_. It is of little moment whether this redundant gas comes from
the water of dilution or from the fermentable matter, as under, if we
can by any means turn it to account.

We have presumed the average quantity of fermentable matter at
seventy-five pounds per quarter; this must be evidently on the best
goods; this will give us a length of three barrels per quarter of malt
of eight bushels, of twenty-five pounds per barrel, specific gravity.
Suppose the apparent attenuation of these goods to be nineteen pounds,
the transparent gravity will be six pounds per barrel, viz.

Gravity of the worts in the cooler just before letting
down into the guile-tun, per barrel, 25 lb.
Apparent attenuation per barrel, 19 lb.
Transparent gravity per barrel, 6
--- 25 lb.

Or take it as it really is, viz. specific gravity
per barrel,
