ESSAY X. 



SECTION IV. 



That the method above described is really more ad- 

 vantageous than that usually employed, I cannot doubt ; 

 because (1) The mercurius dulcis can be prepared with less 

 difficulty, with less expense, and without employing mer- 

 curius corrosivus. (2) It can never become either more or 

 less corrosive, if it be only well edulcorated, and consequently 

 it is always safe. (3) One is never exposed to the vapour 

 which rises in the old method during the saturation of 

 corrosive sublimate with quicksilver, and which is so 

 dangerous to the health. (4) This mercurius dulcis is 

 much finer than the common, which never can be reduced 

 to so fine a powder, however long it is triturated.
