I took a Quantity of Blood from the Body of a Pcr- 
fon dead of the Plague, and mix’d it with warm Wa- 
ter, which Mixture I attempted to inject into the Cru- 
ral Vein of a Dog, but the End of the Syringe being 
too large to enter the Vein, the Experiment did not 
fucceed. 
This made me refblve to try the other Method you 
had propofed to me, which was to lay fome of the 
fame infedled Blood upon the Wound. This I ac- 
cordingly did, and cover’d it with a Drefling, which 
the Dog got off in the Night. I found the next Morn- 
ing that the Dog had lick’d his Wound, and that he 
refufed his F ood. T owards Night he began to bemoan 
himlelf, and gave Signs of an approaching Death. The 
next Morning I found him dead, the Wound being con- 
fiderably fwell’d and gangren’d, and the Edges round 
the Swelling were likewile gangrened. 
Upon opening the Body we found the Liver Ibme- 
thing larger than ulual, with Spots of a livid Purple, 
as in the Bodies of Perfbns dead of the Plague. In 
the Stomach was found a Quantity of black coa- 
gulated Blood, of the Size of a Hen’s Egg. This in 
all Likelihood was what he had fwallow’d upon licking 
the Wound. The Heart was very large, with a black 
grumous Blood in the Ventricles, and the Auricles 
were turn’d blackifli and gangrenous.
