decide whether patients were properly vaccinated or not, 

 nevertheless ventured to inoculate tor the cow-pox. 



Vn. That many persons have been declared duly vacci- 

 nated, w hen the operation was performed in a very negli- 

 gent and unskilful manner, and when the inoculator did not 

 .afterwards see the patients, and therefore could not ascertain 

 whether infection had taken place or not ; and that to this 

 cause are certainly to be attributed many of the cases ad- 

 duced in proof of the incfficacy of cow-pox. 



VIII. That some cases have been brought before the 

 committee, on which they could form no decisive opinion, 

 from the want of necessary information as to the regularity 

 of the preceding vaccination, or the reality of the subsequent 

 appearance of the small-pox. 



IX. That it is admitted by the committee, that a few 

 cases have been brought before them, of persons having the 

 small-pox, who had apparently passed through the cow-pox 

 in a regular way. 



X. That cases, supported by evidence equally strong, 

 have been also brought before them, of persons who, after 

 having once regularly passed through the small-pox, either 

 by inoculation or natural infection, have had that disease a 

 second lime. 



XI. That in many cases in which the small-pox has 

 occurred a second tin)e, after inoculation or the natural dis- 

 ease, such recurrence has been p?rticularly severe, and often 

 fatal ; whereas, when it has appeared to occur'after vacci- 

 nation, the disease has generally been so mild, as to lose 

 some of its characteristic marks, and f'ven sometimes to 

 render its existence doubtful. 



XII. That it is a fact well ascertained, that, in some par- 

 ticular states of certain constitutions, whether vaccine or 

 variolous n'^ttcr be cuiplovcd, a local disease onlv will 

 be excited by inoculation, the constitution remaining un- 

 affected; yet that niatter taken from such local vaccine or 

 variolous pustule is capable of producing a general and per- 

 fect disease. 



XIII. That if a pcrsjjn, bearing the strongest and most
