VACCINATION AGAINST SMALLPOX 179 



several sores upon her fingers, felt no tumours in the axillae, 

 nor any general indisposition. On being afterwards casually 

 exposed to variolous infection, she had the smallpox in a 

 mild way. Hannah Pick, another of the dairymaids who was 

 a fellow-servant with Elizabeth Sarfenet when the dis- 

 temper broke out at the farm, was, at the same time, in- 

 fected; but this young woman had not only sores upon her 

 hands, but felt herself also much indisposed for a day or 

 two. After this, I made several attempts to give her the 

 smallpox by inoculation, but they all proved fruitless. From 

 the former case then we see that the animal economy is 

 subject to the same laws in one disease as the other. 



The following case, which has very lately occurred, renders 

 it highly probable that not only the heels of the horse, but 

 other parts of the body of that animal, are capable of generat- 

 ing the virus which produces the cow-pox. 



An extensive inflammation of the erysipelatous kind ap- 

 peared without any apparent cause upon the upper part of 

 the thigh of a sucking colt, the property of Mr. Millet, a 

 farmer at Rockhampton, a village near Berkeley. The in- 

 flammation continued several weeks, and at length terminated 

 in the formation of three or four small abscesses. The 

 inflamed parts were fomented, and dressings were applied by 

 some of the same persons who were employed in milking 

 the cows. The number of cows milked was twenty-four, and 

 the whole of them had the cow-pox. The milkers, consist- 

 ing of the farmer's wife, a man and a maidservant, were 

 infected by the cows. The man-servant had previously gone 

 through the smallpox, and felt but little of the cow-pox. 

 The servant maid had some years before been infected with 

 the cow-pox, and she also felt it now in a slight degree ; but 

 the farmer's wife, who never had gone through either of the 

 diseases, felt its effects very severely. 



That the disease produced upon the cows by the colt and 

 from thence conveyed to those who milked them was the true 

 and not the spurious cow-pox, there can be scarcely any 

 room for suspicion ; yet it would have been more completely 

 satisfactory had the effects of variolous matter been ascer- 

 tained on the farmer's wife, but there was a peculiarity in 

 her situation which prevented my making the experiment.
