Proof spirit (Chem.), a strong distilled liquor, or mixture
of alcohol and water, containing not less than a standard
amount of alcohol. In the United States "proof spirit is
defined by law to be that mixture of alcohol and water
which contains one half of its volume of alcohol, the
alcohol when at a temperature of 60[deg] Fahrenheit being
of specific gravity 0.7939 referred to water at its
maximum density as unity. Proof spirit has at 60[deg]
Fahrenheit a specific gravity of 0.93353, 100 parts by
volume of the same consisting of 50 parts of absolute
alcohol and 53.71 parts of water," the apparent excess of
water being due to contraction of the liquids on mixture.
In England proof spirit is defined by Act 58, George III.,
to be such as shall at a temperature of 51[deg] Fahrenheit
weigh exactly the 12/13 part of an equal measure of
distilled water. This contains 49.3 per cent by weight, or

Bouvier's Law Dictionary, Revised 6th Ed (1856):
PROOF, practice. The conviction or persuasion of the mind of a judge or
jury, by the exhibition of evidence, of the reality of a fact alleged: as,
to prove, is to determine or persuade that a thing does or does not exist. 8
Toull. n. 2; Ayl. Parerg. 442; 2 Phil. Ev. 44, n, a. Proof is the perfection
of evidence, for without evidence there is no proof, although, there may be
evidence which does not amount to proof: for example, a man is found
murdered at a spot where another had been seen walking but a short time
before, this fact would be evidence to show that the latter was the
murderer, but, standing alone, would be very far from proof of it.
2. Ayliffe defines judicial proof to be a clear and evident declaration
or demonstration, of a matter which was before doubtful, conveyed in a
judicial manner by fit and proper arguments, and likewise by all other legal
methods; first, by proper arguments, such as conjectures, presumptions,
indicia, and other adminicular ways and means; and, secondly, by legal
method, or methods according to law, such as witnesses, public instruments,
end the like. Parerg. 442 Aso. & Man. Inst. B. 3, t. 7.
The Devil's Dictionary (1881-1906):
PROOF, n. Evidence having a shade more of plausibility than of
unlikelihood. The testimony of two credible witnesses as opposed to
that of only one.
