ART LXIX.— EXTRACTION OF SANTONINE. 
Mr. Calloud having put into practice the different pro- 
cesses indicated up to the present time, for obtaining San- 
tonine, has been induced to adopt the following, which in 
part is due to him. 
30 kilogr. of semen-contra (Sem. Santonici,) are to be

slacked lime to saturate the pantonine, and at the same time,

express anew, unite the decoctions, allow it to deposit, de- 
cant the liquid, which you transfer to a large dish, and evap- 
orate to a certain degree of concentration, clarify and pass 
through a flannel. This done, replace the liquid upon the 
fire, and evaporate again to a convenient degree, then pour 
it into a large earthen pan, and add a slight excess of hydro- 
chloric acid. After twenty-four hours of repose, the San- 
tonine will be found more or less pure. By means of weak 
alcohol, wash it, to separate the larger part of the fatty re-

alcohol and charcoal, that it may crystallize.
