ON THE ETHEREAL EXTRACT OF CUBEBS.

faithfully represented by the preparation. For the guidance 
of those who may be inclined to make this oleo-resin for 
medical use, I subjoin a formula: Take Cubebs in pow- 
der one pound avoirdupois, and sulphuric ether a sufficient 
quantity, which is two and a half to three pounds ; intro- 
duce the powder into a displacer, insert the lower end in a 
bottle that fits it, add the ether carefully, and cover the top 
of the filter with a piece of wet bladder, through which se- 
veral pin holes are made. The flow should be very gra- 
dual, and if too rapid the orifice of the filter should be par- 
tially closed with a cork — by attention to this point much 
less ether will be required. The ethereal tincture should be 
introduced into a large retort, heated by a water-bath, and 
the receiver well refrigerated. The distillation should not 
be hurried towards the last. When five-sixths of the ether 
has passed, it should be separated for use, and the eva- 
poration continued in the retort, observing to keep the 
temperature below 120° Fahr., so as not to volatilize the 
essential oil. The product in the retort amounts to two 
ounces, just one-eighth of the Cubebs used. 
This preparation may be administered in emulsion, pills, 
or in capsules ; one drachm representing an ounce of the 
Cubebs.

A table spoonful of this emulsion represents two drachms 
of Cubebs. Should it be desirable to use alum with it, it 
may be dissolved in the water. 
The most complete mode of administering this substance 
is in gelatin capsules, like those of copaiba, and it was in 
this form that Dr. Goddard employed it.
