for the two firft days, and they now were red and a liltfe 

 elevated, as if the infe6tion had taken eftefit, 



6lb Day, Tucfday 28. Inflammation had almoft en- 

 tirely gone off: inoculated a fecond time in both arms with 

 matter from a different patient. 



^d Day of fecond Inoculation, Thurfdav 30. Punftured 

 parts appeared inflamed, 



6th Day, Sunday April z. Inflammation had dtfap- 

 pcnred. Inoculated a third time with limi)id fluid matter 

 from a patient prcfent, and with which matter I had excited 

 the vaccine difeafe in fevcral pcrfons, 



Itb Day of third Inoculation, Friday April 7. The parts 

 inoculated had inflamed and felt painful for two or thre« 

 dayS:, but ^^■ere now well. — Inoculated him a fourth time with 

 fmall-pox matter in both arms. A little inflammation arofe, 

 but nothing more.

 that the evidence in his cafe, of the patient having had the 

 fmall-pox icben a child, is merely that of the patient ; and
