ART. XX. — EMPLOYMENT OF CASEIN AS AN ENVELOPE 
FOR MEDICINES. 
By G. Jozeau. 
In order to disguise the disagreeable odor and flavor of 
pills, and to increase their durability, M. Joseau recommends 
their being coated with casein instead of with gelatin. 
Take fresh casein free from butter, put it for twenty 
minutes into boiling water, press it strongly, and then dis- 
solve it in a sufficient quantity of solution of ammonia, so 
as to form a liquid having the consistence of syrup ; then 
mix it with sugar (about one-tenth of the weight of the 
casein,) evaporate the whole to dryness, and rub to powder 
In order now to envelop pills with it, a small quantity 
of the powder is to be dissolved in water, so as to form a 
thick mucilage, with which the pills are to be moistened. 
They are then to be covered with the powder. The pills 
must be coated two or three times, according to the inten- 
sity of their odor and flavor. After the last coating of 
mucilage, they are to be dipped into slightly acidulated 
water, instead of being covered with powder, and are then 
to be dried. — Pharmaceutical Journal, Dec, 1S49,
