inflammation under the cuticle, where the punctures 

 xvere made, 22d. Inflammation more coniiderable. 

 23d. On this day the inflammation was fomewhat 

 greater, and the cuticle rather, elevated. 



<c 24th. Inflammation much lefs, and only a brown 

 or orange colour remained. 25th. Scarcely any dif- 

 coloration left. On this day he was inoculated with 

 variolous matter, the progrefs of the infection went 

 on in the ufual way, and he had the fmall-pox very 

 favourably. 



u At this time I was requefted to inoculate a 

 young peribn, who was thought to have had the 

 fmall-pox, but his parents were not quite certain ; 

 in one arm I introduced variolous matter, and in the

 fecond day after the operation, the punclured parts 

 were inflamed, though I think the arm in which I 

 had inferted variolous matter was rather more fo

 increafed, and looked much the fame as in the pre- 

 ceding experiment. 4th. The inflammation was 

 much diminimed, and on the 5th almoft gone. He 

 was expofed at the fame time to the natural infedti-

" I have frequently obferved (and believe mod 

 practitioners have done the fame), that if variolous 

 matter be inferted in the arm of a perfon who has 

 previoufly had the fmall-pox, the inflammation 

 on the fecond or third days is much greater, than 

 if they had not had the difeafe, but on the fourth 

 or fifth it difappears. 



" On the 23d I introduced blood into the arms 

 of three more children, taken on the third and 

 fourth days of the eruption. The appearances were

 third. They were afterwards inoculated with vari- 

 olous matter, and had the difeafe in the regular way.
