T.X'Crtments refpe^lng the Vaccine 'D'lfeafe. 313 

 t-he public, the valuable materials tranfmitted to me. It 

 will, however, perhaps be not without utility at this lime 

 firfl to ftate a few general refults from the vaccine inocula- 

 tion ; and fecondly, to relate fonie trials, from which I ap- 

 prehend conclufions can warrantably be drawn to priimotc 

 the invelligation now going forward. 



Not much more than fix months have elapfed fince the 

 opportunity was afforded, by the breaking out of the vaccine- 

 dijeafe in two principal milch farms near London, of obtain- 

 ins: matter for propagating the fame difeafe among human 

 creatures. The tieiu inoculation was immediately introduced 

 in London, and foon afterwards in the neighbourhood, as 

 well as in many provincial fituations. It is with lincere 

 fatisfaclion that we can now reckon, at the fevveft, 2000 pet- 

 fons who have palTed through the cow-pox by inoculation. 

 But in this number I include the very large proportion far- 

 nifhed by him who, fo beneficially to the public, and ho- 

 nourably to himfelf, poilcires the office of phyfician to the 

 Small-pox Hofpital. From the above experience we receive, 

 as I expefted, important information. 



I. Of the above number it appears that one patient died ; 

 (Woodville's Reports, p. 151.) and to avoid controverfy, 

 let us allow that the death was occafioned folely by the ino- 

 culation. Now, according to thejudefl: calculation I have 

 joeen able to make, as in the inoculated fmall-pox one in.

* I am fully aware that fo great a proportion as one in 200 will not be 

 allowed by many praftitioncrs. An J to perfons who have btcn toiJ, and 

 believe, that inoculation for the fmall-pox " fcarcely ever Jots any liarin 

 — tii^t certain praftitionert have inoculated many thoufands without lofing

 culated cafe in their whole lives"—! fay to fuch perfons, no advantagt, o» 

 /he fcore of faving life, will be allowed from the cow-pox. But 1 have 

 convcrfcd with many candi4 and txpcricnced prafliiiontrs, aud they are 

 >vcll fatisficd that I am warranted in the aliovc ftatemcnt of deaths in tlie 

 iucculatcd variola. I fcc^ leave to fay farther, that £ believe more pcr-
