liquid drawn off from the gypsum. In this case it is not advisable 
to previously dilute the sulphuric acid with water, as the gypsum 
then assumes a crystalline loose condition, subsides with difficulty, 
and contains much fluid. 
In both cases the acetic acid contains a small quantity of muriatic 
acid, also sulphurous acid; and, in the latter case, also a small pro- % 
portion of gypsum. Oxyde of lead is now to be added, and heat 
applied till the acid reaction is feeble. The precipitate retains sul- 
phurous acid from the gypsum, and also sulphate of lead, and chlo- 
ride of lead. The solution of the acetate of lead yields a yellowish 
sugar of lead, containing a small quantity of chloride of lead, but 
which is generally sufficiently pure for dyeing purposes, and can be 
still further purified by recrystallization. — Pharm. Journal, from
