342 A COMPENDIUM OF 
Oleum Myristice Expressum, Expressed 
Nutmeg Oil, alsoknown as Mace Oil.—The con- 
crete fixed oil is obtained from the nutmegs by 
exposing them (bruised and placed in a canvas 
bag) to the steaming process, after which they 
are subjected to pressure between heated plates 
of iron. The oil, when it first exudes from the 
bag, is liquid, but after cooling it becomes of a 
butter-like consistence, soft and unctuous to the 
touch, of a light brown or orange-yellow color, 
more or less mottled in appearance, with the 
characteristic odor and taste of the nutmeg. It 
melts at 88° F., is partially soluble in alcohol 
and ether, and contains the following constitu- 
ents: About 6 per cent. of volatile oil, 7o per 
cent. of myristin, 20 per cent of olein, 3 per 
cent. of reszn, and the balance salts, ‘The spe- 
cific gravity is about 0.95. The myristin or 
myristicin, as it is sometimes called, upon sa- 
ponification yields glycerine and myristic acid. 
The expressed oil is artificially made and sold 
as the genuine. Artificially made by mixing 
various fatty substances, such as spermaceti,

with the volatile oil of nutmeg. It is not of-

for plasters.
