A universal formulary : containing the methods of preparing and administering officinal and other medicines : the whole adapted to physicians and pharmaceutists . d into 100 parts or de-grees. The lowest division marked 0,at the bottom of the scale, denotes thespecific grayity of pure water at a tem-perature of 15° Cent.; and the highestdivision, at the top of the scale, the spe-cific gravity of absolute alcohol at thesame temperature. The intermediatedegrees indicate the number of volumes of absolute alcohol in 100 volumesof the spirit tried. The instrument is accompanied by a table for correctingthe numbers marked on the scale, when it is used at any other temperaturethan that of 15° Cent. Sikes^s hydrometer is used exclusively in the collection of the spirit reve-nue. It consists of a spherical ball or float, and an upper and a lower stemmade of brass (a b e. Fig. 4); the upper stem (&) has ten principal divisions,numbered 1, 2, 3, etc., which are each subdivided into five parts ; the lowerstem- (c) is made conical, and has a pear-shaped loaded bulb at its lower ex-tremity. There are nine movable weights (6, Fig. 5), having the form of. A Specific Gravity Bead. Gay Lussac3Alcoometre. 36 INTRODUCTION. Fig. 4 circular disks, and numbered 10, 20, 30, and so on to90. Each of the circular weights is cut into its centre,so that it can be placed on the inferior conical stem Fig. 5.
