of it. A 2cl person that died after inoculation, was an apothecary's house- 

 keeper, that was out of town, till an Indian maid got the distemper in the same 

 house, and removed, and died. On which this woman coming to town, her 

 master undertook to perform the operation upon her, which by the way was the 

 first and last that he ever performed ; and on the 3d day after the inoculation, 

 the small-pox came out upon her very full; from which it was plain, that she 

 had taken the infection before, in the common way. 



The 3d person that died after being inoculated, was a gentleman who lodged 

 in the same house with my wife and self at Roxbury, who was under great and 

 extreme infirmity of body, that we feared he would have lived but a short time 

 under it. His friends much persuaded him to make use of inoculation, be- 

 lieving that it would have carried off his illness ; but when he made the experi- 

 ment, he had not strength to go through with it. He was about 45 years 

 of age. 



His sister was the 4th person that died on this operation. She was about 

 40 years of age, of great indisposition of body, and weak, as was her brother. 



The 5th, that died on inoculation, was a woman servant in a house, where 

 the whole family, to the number of 8, were inoculated at the same time. She 

 lay in a cold upper room during her illness, and was much neglected, the whole 

 family being down together, so that she died merely for want of a little attend- 

 ance. This was in the town of Roxbury, where 13 men, masters of families, 

 got the small- pox, and all died ; which inclined the people to make use of ino- 

 culation, having before been much against it, and 43 men were inoculated 

 there, who all did well. The minister of the town was the first, who put it in 

 practice there, much against the mind of his people at first, though afterwards 

 they were very well pleased with it, seeing with what great success it was at- 

 tended ; and then whole families came into it, and underwent the operation. 

 There were in all at least 280 persons inoculated, that I knew of, and I suppose 

 there might be about 20 or 30 more, but of those I can give no certain 

 account.
