We have estimated the equivalent of carbonate of potash (Potass carhonas of the London Pharmacopoeia), and of carbonate of soda, at 84 each. Mr. Phillips makes the former 835; but .5 may be allowed for impurity and extra moisture: the (sesqui-) carbonate of soda he makes 83, but the composition of the best commercial specimens approaches nearer to the bicarbonate, which is 85.

Table of the Relation between the Principal Areometers for Liquids lighter than Water.

[The first five columns are from Soubetran, the last from Dr. Christ [son and Mr. Redwood. The degrees of Gay-Lussac's alcohometei indicate the per-centage by measure of pure alcohol; but are not quite exact as here given, the fractions being neglected.]
