convulsions continuing, with an unequal and low pulse, and as there was little 

 appearance of matter, blisters were applied, as near to the parts affected as pos- 

 sible, in order to make a revulsion from the heart, and throw oft" the morbid 

 matter by the wounds. In about 3 days this point was gained, the convulsions 

 began to abate, and the wounds to digest; in 4 more, he found a cessation of 

 symptoms, except a faintness and lowness of spirits, which hung upon him for 

 a great while after, which pestilential fevers are known always to leave behind 

 them. 



He supposes he might receive this infection, as much by inspiration as con- 

 tact; for some of his assistants, who were in the room only, and never touched 

 a drop of the liquor, found themselves much disordered, and afterwards broke 

 out with red and livid eruptions; which sufficiently showed, that not only the 

 liquor itself, but the effluvia also, were in the highest degree subtle and ma- 

 lignant.
