Vacctnni Inoculation hi JVales. 303 



effect. Every fcruple was therefore removed, and I defiled 

 Dr. Pearfon to fend me, in a letter, fettle of his genuine 

 matter on a thread, that I might inoculate both my own 

 children, for the fatisfaction of all who might wi(h to have 

 evidence of its effects : and (June 29, 1799) in the prefence 

 of Mr. J. Collins, Mr. Braine, and the late apprentice of 

 Mr. Sylvefter, I inoculated them both. The boy, who he- 

 fore had had the fmall-pox, did not ,take it ; but the little 

 girl, who never had either, went well through it, without 

 any previous preparation, without any alteration in her food 

 or manner of living, and with only about two hours ill- 

 nefs. She has fincc oeen inoculated for the fmall-pox, and 

 expofed in every manner to its infection, but it is certain 

 cannot have it. 



" From her arm I inoculated feveral children, among whom 

 were two of Mr. Ayrton's ; each of which I directed might 

 fleep with one who never had been inoculated for either. 

 The two that were innoculated went well through it, and the 

 two that fleptwith them did not catch it. By this it appears 

 that it is not infectious, and that any part of a family may- 

 have it without communicating it to others. 



€ f An opinion has been delivered about the town, that it is- 

 pofiible for thofe who have had the cow-pock llill to be liable 

 to have the fmall-pox. This I may fafely contradict; as it 

 is an aflertion made without proof, or without inquiry after 

 proof: for, notwithstanding every eye has been open to dif- 

 cover whatever might happen, and every attempt made to 

 afcertain it, there is not upon record one Angle inftance. 



" Had thofe who have lately been cutoff* by the fmall-pox 

 in Swanfea been inoculated for the cow-pock, it is more 

 than probable they would all have been faved :, and in con- 

 fequence of its increafing fatality 1 was applied to by many, 

 who trufted my afTertions, to procure genuine matter from 

 London. I have juft received fome from Dr. Pearfon, and 

 have inoculated the children of Capt. Nichols, on the 

 Burrows, and the two others of Mr. Ayrton, who may be 

 feen by any one defirous of further information. From 

 them I am willing to inoculate fuch as are fully convinced 

 of its utility, and pledge myfelf, under Providence, for their 

 fafety. 



" Obstructions from medical men will fometimes prefent 

 themfelves, through prejudice, or fear, or interett. Preju- 

 dice I conlider to be a determination to abide by old opinions 

 whether right or wrong: and with men who perfevcre in 

 detected error, it is ufelefs to reafon, and foolifh to con- 

 tend. Fear will operate with thofe who are apprehenfive
