this description, in which the members of the Society gave the results of their- 
experiences, without reserving any secrets, afforded the best possible illustra¬

powders, in the state in which they are now used in medicine, could not be 
produced by the old process of pounding with a pestle and mortar. The use 
of machinery on the large scale had superseded that method of operating, 
by the production of much finer and better-looking powders. Several at-
