warm situation to dry; the whole is then weighed, and so 
much powdered sugar added to it as is found requisite to 
bring the weight of the dried mixture to 3 pounds (troy.) 
In drying the mixture of the extract and sugar, the alcohol 
evaporates, and carries with it the water which had remain- 
ed in the extract, which renders the mixture so much the 
lighter. The preparation is now pulverized, and passed 
through a fine hair sieve. Six grains of the powder contain 
exactly one grain of extract. It keeps exceedingly well in 
a dry situation, even when the air has access. 
Extract, mixed with sugar in this manner, may be dis- 
pensed very easily and quickly, and it may be readily mix- 
ed with other substances; it may, moreover, be kept for 
years, and in a cool place, without spoiling. 
M. Gauger recommends the preparation of Musk in the 
same manner, by rubbing one ounce of musk with an ounce 
and a half of alcohol, as before, and then triturating with 
3 ounces of sugar, drying, and again pulverizing. Six grains 
of this powder represent one of musk, and in such a form as 
to be instantly available for administration.
