 or can be easily obtained by a pharmacist operating 

 upon the small scale." 



4. "The final thorough trituration of the dry 

 powder reduces the soluble and active constituents 

 of the drug to a pulverulent condition, the diluent is 

 soluble and the fine state of division of abstracts is 

 the most favorable condition that a powder can pos- 

 sess to secure efficient medication."
