80 DATURA STRAMONIUM, 
the heat of boiling salt water to the thickness of 
honey; it is then suffered to cool, put up in glaz- 
ed vessels and moistened with alcohol. The ew- 
tract is prepared by immersing a pound of the 
leayes in three gallons of water and boiling down 
toone. The decoction should then be strained 
and stand six hours to settle, after which it may 
be drawn off and evaporated to the proper consis- 
tence. When the seeds are used, the decoction 
should stand a longer time to separate the oil with 
which the cotyledons abound, before evaporation. 
A larger amount of extract may be obtained by 
boiling the portion, which has been used, a se- 
cond time in a smaller quantity of water, and 
mixing the two decoctions before evaporation. 
For the tincture one ounce of the dried leaves is 
to be digested for a week in eight ounces of proof 
spirit, and filtrated through paper. In making 
the ointment, a pound of the fresh leayes may be 
simmered in three pounds of hog’s lard until the 
leaves become crisp. It is then to be straineds 
and cooled gradually. 
The period for gathering the leaves is from 
the time the plant begins to flower, until the ar- 
rival of frost.

to vary in strength according to the circumstances
