pounded glass, pewter, brass and iron, which frequently 

 caused a state of irritation not easily allayed. 



Emetic tartar given in two drachm doses daily, for 

 a week, in bran mashes, seldom fails to weaken the 

 worms so much that they can be carried off by means 

 a purging ball composed of six drachms of aloes, two of 

 ginger, and two of emetic tartar. I have never known 

 this treatment fail. Much caution must be used in 

 administering emetic tartar. Its action should be care- 

 fully noted, and immediately any irritation is apparent 

 the quantity must be lessened, or its use prohibited 

 entirely. This, however, may be taken as a rule, that 

 when any irritation is caused by the use of emetic 

 tartar, it may safely be concluded that the object for 

 which it was given has been effected.
