l83 Vaccine Inoculation, 



lieve, it will be found that 2000 cafes had by that time been 

 afforded for the public by Dr. Woodville and myfelf, and 

 the perfons with whom I was in corrcfpondence, and who 

 are mentioned in the papers alluded to. By this time, too, 

 fame dilfirulties appear to have been removed which had 

 been nccafioned, in a great meafure, bv fome fafts ftated to 

 the public by Dr. Jenner. In particular, I publifhcd expe- 

 riments of inoculation in the paper alluded to: — ifi:, Of in- 

 oculating perfons with the cow-pock who had undergone the 

 fmall-pox, to fl)ow that they could not take the cow-pock 

 after the fmall-pox, contrary to Dr. Jenner : 2dlv, Experi- 

 ments to (liow that perfons could not take the cow-pock both 

 locally and conflitutionally who had already gone througli 

 the cow-pock, alfo contrary to Dr. Jenner : 3diy, iSJany per- 

 fons had bv this time made experinietits to Ihow that the 

 cow-pock did not originate in the grcafe of hortcs' heels, as 

 Dr. Jcnrer had afl'ertcd. Thefe fentiments will be found in 

 a printed flatenient, which I beg to deliver in as publiflied 

 by me. 



In the fpring of the year 1799, whild the above-ftated evi- 

 dence was collcfting, a fecond j>ublication appeared from 

 Dr. Jenner, adding nothing but a few cafes of inoculation 

 further of the cow-pock, but recouimending caufiic or ef- 

 charotic applications to the inoculated parts in the cow-pock, 

 not found ncceflary by myfelf or the medical perfons alluded 

 to in my evidence: and 1 confuler that the didinctive cha- 

 rafters of the cow-pock were uiiderllood belter by fome of 

 the above alluded to perfons than by Dr. Jenner. 



The vaccine inoculation was next confulerably eflabliflied 

 by the Cow-pock Inftitution, of which I was one of the 

 founders, the cirrangcment for which commenced at the very 

 clofe of the year 1799 ; which Inltitulion has been the prin- 

 cipal office, I apprehend, for fupplying the world in general, 

 and the army and navy in particular, with matter ; and where 

 a regular regifter is kept of each of the cafes inoculated, more 

 fully and accurately than had been done any where before or 

 lince that time ; where the authenticity of the cafes, from 

 the nature. of the inftitution, is eflabliflied in a manner that, 

 I apprehend, will be confidercd as unexceptionable. 1 his 

 appears from 1 regilter of above 700 caTes already entered, 

 and open to the inlpeftion of the fubfcribtrs. Bv this time, 

 namely, the clofe ■ of the year 1799, I think I can make it 

 appear that about 4000 perfons have been inoculated bv Dr. 

 Woodville, niyiclf, and correfpondents, which can be reierred 

 to. I here clofe my evidence, as I confider it of very fmall 

 importance, comparati\(;ly, what was done by others after
