COTTON SEEDS. 
503 
A few years ago the oil was noticed in the journals in con¬ 
nection with preparations of pharmacy, to be substituted for 
oils in liniments and ointments, for which it is adapted by 
its properties as an emollient, but nothing definite was arrived 
at. Being cheaper than even the commonest grades of olive 
oil, and resembling it so much in its behaviour, it is pecu¬ 
liarly fitted for the preparations of the pharmacopoeia in which 
the oil is used. Mixed with aqua ammoniae in the officinal 
quantities for " Liniment. Ammonioe,” it makes a product 
which has all the essential properties that are indicated by 
the olive oil, and has the advantage of not forming so thick a 
mixture, thereby making it more convenient. In the (i Lin. 
Camphorae,” it seems to serve exactly the same purpose as 
the officinal oil. 
Lead plaster made with the cotton-seed oil has been sub¬ 
stituted with advantage for the officinal, and has been used 
to mix with it the amount of fifty per cent, by some manu¬ 
facturers of the plaster. This, made with the cotton-seed 
oil alone, forms a handsome, light-coloured plaster, appa¬ 
rently equal in all respects to the English, with the excep¬ 
tion that it does not become hard enough to keep its 
shape, in the usual form of selling it. But when mixed with 
olive oil in equal proportions, this difficulty is entirely over¬ 
come. 
The cost of the plaster made with the cotton-seed oil, using 
the best English litharge, is twenty cents per pound. This 
difference in the cost, combined with the practicability of 
using it, will recommend it to the more careful examination 
of druggists who deal extensively in this preparation.— Amer .
