veflels, was of a dark colour, in a fluid ft ate, and did 

 not coagulate on expofure to the atmofphere. 



EXPERIMENT III. 



After the interval of one day, the fame fnake was 

 again brought, and made to bite a young puppy in the 

 hind leg, but above the part to be bitten, I had pre- 

 vioufly tied a ligature : immediately after he was bit- 

 ten, the wound was fcarified and wafhed with a folu- 

 tion of lunar cauftic. The dog did not appear to feel 

 any other injury than what might arife from the liga- 

 ture round his leg : half an hour after he was bitten, 

 the ligature and dreffing, which conlifted of lint dipped 

 in the folution of lunar cauftic, were removed. The 

 dog foon began to link, gradually loft the ufe of his 

 limbs, breathed quidk, was convulfed, and died in 

 half an hour more. On opening this dog, the blood, 

 coagulated readily on being emptied from the veflels. 



EXPERIMENT IV. 



Another dog was now bitten in the hind leg, and 

 immediately after a ligature was applied, as in the pre- 

 ceding experiment : the wound was fcarified and walh- 

 ed as before, and for two hours the dog continued 

 lively and well, when the ligature was removed. 



EXPERIMENT V. 



Another puppy having been bit in the fame 

 place, the wound was ftmply fcarified, and waftied 

 with a folution of the lunar cauftic, and for two hours 

 the animal continued free from difeafe. In thefe two 

 laft experiments the dogs were very young, and fed 

 by their mother's milk : at the expiration of the time 

 mentioned, they were carried to her, but Ihe avoided 

 them, and they both died in the courfe of the day.
