 says he, " of the vaccine matter in some inveterate 

 ulcers produce a permanent cure* ?" 



" Count de la Roque takes notice of a severe epide- 

 mic hooping cough, which prevailed at Lyons, during 

 which it was observed, by medical men, that those who 

 had been inoculated with cow pock either escaped the 

 disease entirely, or had it in a mild degree. I have . 

 known Pertussis to get much better after small-pox ino- 

 culation. 



" Many more instances might be adduced in support 

 of the opinion entertained by those authors, of the effi- 

 cacy of cow pock in removing several diseases. Any 

 experience I have hitherto had does not warrant me in 

 hazarding an opinion upon this important part of ouf 

 subject. I have, indeed, seen two or three cases in 

 which children seemed to have been relieved from ob- 

 stinate eruptions by it : though, generally speaking, I 

 am rather averse to inoculation, when other diseases are 

 present, for reasons ^vhich I shall hereafter state. For 

 my part, I shall not require any further benefits from the 

 new inoculation than those already established, but will 

 rest content with the assurance, that, without injuring 

 the constitution in the smallest degree, it renders it for 

 ever exempt from the contagion of small-pox. To be 

 more convinced of the fact, that cow pock is not preju- 

 dicial to the general health, I lately visited a great num-

 lately, the application of vaccine virus to cancerous sores. The 

 experiment has not, 1 believe, been yet put in practice.
