340° g A COMPENDIUM OF 
freezing point. Cottonseed oil is very slightly 
soluble in alcohol, but freely so in ether. Acid 
sulphuric, when shaken with the oil, forms a 
turbid, red-brown mixture, The oil when first 
expressed is said to contain as much as 18 per 
cent. of mucilage, album, olen, palmitin and 
coloring matter. ‘This mucilaginous substance 
probably accounts for its turbidity and drying 
qualities. The better kinds of oz/ are largely 
used to adulterate the olive oils. Cottonseed oil 
is largely manufactured in Europe and this 
country. Seven million gallons is the yield in 
Europe, which amount is increased by many 
million gallons in the United States. ~The oil 
enters into the following officinal preparations : 
LINIMENT UMAMMONIA&, LINIMENTUM CALCIS, LIN- 
IMENTUM CAMPHOR&, and LINIMENTUM PLUMBI 
SUBACETATIS, 
Oleum Morrhue, Cod-Liver Oil.—This fixed 
oil is obtained from the fresh livers of the vari- 
ous kinds of Cod Fish, the Gadus Morrhua, 
Gadus Callarias, Gadus Molva, Gadus Carbona- 
Tias, etc. Theseare technically arranged into the 
Class Pices, Order Teleostia, Family Gadida. 
The fishes from which the livers are obtained 
are of various sizes, ranging in length from 2 
to 3 feet, and weighing from 3 pounds up to 20, 
The different species are found in the waters 
bounded by the coasts of New England, New- 
foundland, Nova Scotia and Norway. The oil 
1s extracted from the livers of the fishes by heat, 
the better qualities by heating with water or by 
steam; it is then subjected to extreme cold, the 
frozen mass finally placed in bags and put un- 
der the press; the pure oil exudes through the
