    we . SHOWING THE SPECIFIC GRAVITY CORRESPONDING WITH THE SEVERAL DEGREES OF BAUME’S AND BECK’S HYDROMETERS. Baumé’s hydrometer is usually employed in France. In this instrument, the sp. gr. of distilled water is assumed as the zero of the descending scale, cending scale, in relation to lighter fluids. In the Pharmacopeia Batava, a modification of the instrument has been adopted, in which the sp. gr. of dis- tilled water has been assumed as the zero of both scales. This modification has also been adopted by the authors of the French Codex, and the Sp. gr. corresponding to the several degrees of this scale is given below. Beck’s hydrometer is used in Germany. For Liquids lighter than Water. = - a] Specific Gravity. i Specific Gravity. ByB Bh In Pharm. In Pharm. |By Baum Batava. By Beck. By Baumé.
