88 Tables for reducing Degrees of Bedtime's Areometer 
mon salt in water as high as 80° of the instrument, as 
given by Hassenfratz in the 28th voL of the An. de 
Chim. p. 298, which ought therefore to be the same, but 
which actually differ in no inconsiderable degree. 
We have further added the corresponding specific gra- 
vities with many of the degrees of the hydrometer from 
18° to 45°, as given by R. Eingley, Esq. King’s Assay- 
Master of the Mint, (Philosophical Magazine, vol. xii.) 
from actual experiments with a Paris hydrometer. This 
includes a specific gravity from 1.150 to 1.485, which, 
with acids, is sufficient for most of the purposes of the 
assayer or mineralogist.

The Hydrometer for Spirits is constructed exactly on 
the same principle, and the mode of graduation is also 
the same, that is, by a solution of salt, and not by mix-
