ferent ways, in Europe: in England, has been made by 
chopping bones into small pieces, extracting the marrow _ 
and fat by boiling, then distilling from an iron cylinder into 
a leaden receiver, and cooling by a refrigeratory, which — 
-forms the cover, and contains about four inches. of water. 
This process yielded six parts impure alkaline liquor, a 
five of fetid oil : the latter was skimmed off, and powder- 
ed gypsum mixed with the former. In the subsequent 
steps of the process, common salt was added ; and by eva- 
oration and other steps, a PR Sere 5 is obtained, 
The cakes are hemispherical ; about an inch thick ; elas- — 
tie ; and when broker ‘towards the convex surface, white, 
~ striated, and opaque—towards the concave, have a more 
crystallized appearance, and nearly semi-transparent. Some- 
times met with in conical masses, which are deliquescent, 
owing to the presence of muriate of lime—hence unfit for . 
medical use. Inferior sort imported from East Indies.
