152 PREPARATION OP SOLUBLE CREAM OP TARTAR. 
ART. XXXVIII. — PREPARATION OF SOLUBLE CREAM OF 
TARTAR. 
PY M. CAMBORNAC. 
j$. Bitartrate of potassa 400 gr. 
Borate of soda 200 sr. 
o 
Tartaric acid 11,000 gr. 
I dissolve the salts and the acid together; when the solu- 
tion is complete, I clarify it with white of egg, and filter. 
I again put it on the fire and continue the operation as di- 
rected by the Codex. The product is of a decided acid 
taste, very soluble, and possessed of purgative properties as 
active as those of ordinary cream of tartar; and is decidedly 
preferable to the latter.
