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.

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

about 60, 70, and 80 per cent of alcohol, are sometimes
called second, third, and fourth proof spirits
