Bau`mé" (?), a. Designating
or conforming to either of the scales used by the French chemist
Antoine Baumé in the graduation of his hydrometers; of or
relating to Baumé's scales or hydrometers. There are two
Baumé hydrometers. One, which is used with liquids heavier than
water, sinks to 0° in pure water, and to 15° in a 15 per cent
salt solution; the other, for liquids lighter than water, sinks to
0° in a 10 per cent salt solution and to 10° in pure water. In
both cases the graduation, based on the distance between these
fundamental points, is continued along the stem as far as
desired. Since all the degrees on a Baumé scale are thus
equal in length, while those on a specific-gravity scale grow smaller
as the density increases, there is no simple relation between degrees
Bé. and Sp. gr. However, readings on Baumés scale may be
approximately reduced to specific gravities by the following
formulæ (x in each case being the reading on
Baumé's scale) : (a) for liquids heavier than
water, sp. gr. = 144 ÷ (144 - x);
(b) for liquids lighter than water, sp. gr. = 144
÷ (134 + x).
