5. That many hundreds have been re inoculated with 

 vaccine matter without being able to reproduce the cow- 

 pock. 



6. That according to considerable experience of this In- 

 stitution, persons arc alike unsusceptible or susceptible of 

 the small-pcx and cow-pock after variolation or vaccination. 



7. That re-inoculation with vaccine is preferable to va- 

 riolous matter, because it is desirable to avoid the risk of 

 infecting others l:y disseminating sniall-pox infection; and 

 because the vaccina is rarely attended with danger or with 

 severe symptoms. 



8. That the cow-pock matter and variolous matter are 

 distinctly difierent species of matter, in the just sense of the 

 term species or kind. 



9. That there is now good evidence, that in the cases of 

 failure the constitution had generally been rendered less 

 susceptible of violent action from the agency of the small- 

 pox matter. 



10. That it does not appear that any new disorder is liable 

 to be occaiioncd after vaccmation, excepting proliably cer- 

 tain eruptive complaints, which, however irntatino-, have in 

 no instance produced any serious injury; and it appears 

 that certain diseased states which come on after the cow- 

 pock do not su[)ervene so frequently as after the small- pox. 



11. That although it does appear from the London bills 

 of mortality, that 420 fewer deaths per annum, on an ave- 

 rage, have occurred during the twelve years of vaccination 

 than during t!ie tv\elve preceding years, yet the conclusion 

 that the diminished mortality has been occasioned bv vac- 

 cination is liable to error, but the probability is m favour of 

 the new practice. 



Mr. Richard Walker, of Oxford, whose valuable com-

JV'Jr. Walkf-r has been upwards of ilO years Apothecary
