Vaccine Inoculation* 403 



A. Yes: I have been acquainted with the practice fince 

 January 1799. ' ano imn k li * s uut jnftice to Dr. Jenner to 

 ftate, that 1 am acquainted with the practice of inoculation 

 of perfons for the imall-pox, who on good evidence were faid 

 to have gone through the cow-pox fince June 179S : the re- 

 fult of which was, that they could not receive the fmall-pox 

 infection. 



Was it from the communications of Dr. Jenner, or any 

 other fource, that you derived your knowledge of the vaccine 

 inoculation ? 



A. In the firft inftancefrom Dr. jenner: afterwards T got 

 information from other foil fees. — [Letters delivered in.] 



Do you imagine that the information contained in thefe 

 letters arofe from Dr. Jennifer's publication of his difcovery 4 or 

 from a previous knowledge of vaccine inoculation ? 



A. I imagine they were independent of each other. 



Did you ever hear that Dr. Jenner had communicated his 

 difcovery to Mr. John Hunter many years previous to this 

 correfpondence ? And is it not known that in his lectures 

 fome years before his death he mentioned it publicly ? 



A. Not the praclice of inoculation ; but that Dr. Jenner 

 had acquainted him that peffons whb had the cow-pox could 

 not take the fmall pox, and that nobody had been known to 

 die of the cow-pox. 



IJad you anv other communications with the Rev. Her- 

 man Drew, befides the letters delivered in, upon the fubjecl: 

 of vaccine inoculation ? 



A. None that I think relate to the queftion. 



Does Mr. H. Drew lay claim to the difcovery of inv u- 

 lating with the vaccine matter from one human being to an- 

 other ? 



A, No; that is exclusively* Dr. Jenner's. 



Do you know when the facts Hated in the correfpond- 

 eenc which you delivered to the committee actually took 

 placef ? 



A. Only that they took place, in all probability, earlier than 

 the year 1798. 



On what do you ground that opinion ? 



A. Becaufe, immediately upon the publication of Dr. Jen* 

 ner's work in 1798, I wrote to the gentlemen who furnifhed 

 that information, namely, the Rev. Mr. H.Drew, Dr.PuItency, 



* Dr. Pearfon, in his book lately pub'iflied, finds that this is n t ftri&ly 

 correct ; for vaccine inoculation from the human l'ubjett had been previ- 

 ously inftituud. 



f The dates were fubre^uently obtained, and arc printed in Dr. Pear- 

 W's work juft publifhed.
