be more fatal, whenever, for the purpofcs of me- 

 dicine, corrolive fublimate is di Helved i'i fpirit 

 of wine, or a portion of crude mercury is add- 

 ed to moderate its corrofive quality. Of this 

 cruel and diabolical fraud mention was made by 

 the writers of the lad century; and we arc 

 therefore furprifed at the ill-judged and much 

 too late delicacy of Dollie, who thought him- 

 felf not permitted to reveal cxprefly the poi- 

 fonous fubllancc with which corrolive fublimatc 

 might be adulterated. We fiiall have occalion, 

 a little fulher on, to fay more upon this fub- 

 jcd ; at prcfent we have it in view to (hew, as 

 fur as we are able, in what manner corrolive 

 mercurial fublimate ought to be ])rcpared in 

 our laboratories. It mull be acknowledged, 

 however, that the greater number of methods 

 f"" this purpofc are exceedingly tedious and ev- 

 penlive, and replete with danger. The labour 

 required to mix three or fuur fubflunces is ex- 

 ceedingly great, and does not fuccced properly, 

 except in very large vefiels, winch, during the 

 progrefs of the operation, are very often broken. 

 And add to this confederation, that the vapours 

 of the nitrous acid are exceedingly noxious, and 

 frequently produce rucmoptylis, and other dif- 

 ordcrs, in thofe who infpirc them. The danger 

 is however not of fuch u nature, as that it malt 

 always attend tlie preparation of mercurial fub- 

 nmate. Tiiat method which requires the leu'l.
