e by the strength of spiritous liquors of
different denominations. And hence, for the business of the exciseman, a
table has been constructed, expressing the strength or specific gravity
of mixtures of different proportions of spirit and water, at different
degrees of temperature; and according to this table the duty on spirit
is now levied.

Brandy and rum is seizable, if sold by, or found in the possession of,
the dealer, unless it possesses a certain strength.[89] The following
are the words of the Act:

"No distiller, rectifier,[90] compounder or dealer, shall serve or send
out any foreign spirits, of a lower strength than that of 1 in 6 under
hydrometer proof,[91] nor have in his possession any foreign spirits
mixed together, except shrub, cherry or raspberry brandy, of lower
strength than as aforesaid, upon pain of such spirits being forfeited;
and such spirits, with the casks and vessels containing the same, may be
seized by any officer of Excise."

We have, therefore, a ready check against the frauds of the dishonest
dealers, in spiritous liquors. If the spirit merchant engages to deliver
a liquor of a certain strength, the hydrometer is by far the most easy
and expeditious check that can be adopted to guard against frauds of
receiving a weaker liquor for a stronger one; and to those individuals
who are in the habit of purchasing large quantities of brandy, rum, or
other spiritous liquors, the hydrometer renders the greatest service.
For it is by no means an uncommon occurrence to meet with brandy, rum,
and other spiritous liquors, of a specific gravity very much below the
pretended strength which the liquor ought to possess.

The following advice, given to his readers,[92] by the author of a
Treatise on Brewing and Distilling, may serve to put the unwary on their
guard against some of the frauds practised by mercenary dealers.

"It is a custom among retailing distillers, which I have not taken
notice of in this directory, to put one-third or one-fourth part of
proof molasses brandy, proportionably, to what rum they dispose of;
which cannot be distinguished, but by an extraordinary palate, and does
not at all lessen the body or proof of the goods; but makes them about
two shillings a gallon cheaper; and must be well mixed and incorporated
together in your retailing cask; but you should keep some of the best
rum, not adulterated, to please some customers, whose judgment and
palate must be humoured."
