the Royal College of Phyficians, and 
Phyfcian Extraordinary to the City of 
Pasay Lying-in Hofpital, ftaied, That 
he looked upon Dr. Jenner to he the dif- 
coverer of vaccine-inocuiation, Hethought 
that moculation of the fmall pox had in- 
creafed the number ef deaths. About 
the year 1773, he paid particular atten- 
tion to this fubject, which afforded fome 
ebfervations applicable to the prefént im- 
quiry, and deciiive upon a large feale of 
calculation, which a table by figures more 
clearly evinced. The experience of foity- 
two years. preced.ng the introduction of 
wmoculation into this country, was alread 
placed ina clear point of view in the Phi- 
lofophical Tranfaétions, by Dr. James 
jorin, who was a languine advocate for 
mroculaiion, and whofe teftimony was 
therefore unexceptionable. His numbers 
were taken from the yearly bills of mor- 
tality, and the reafon why the fourteen 
years from 1686 to T701 were omitted, 
was, becaule in the dlls of thofe years 
the account of the {mall pox and mcafles 
were not diftinguifhed, asia the preceding 
and following yeais, but were joined to- 
gether in one article, fo that from them 
no certain account could be drawn of the 
pumber of perfons that died of tne {mall- 
pox. It appeared by thefe tables, that 
out of 4,005,279 burials within the laft 
forty-two years, 1742 perfons more have 
died of the {mall-pox than the propor- 
tionate number, as colleéted from the ex- 
perience of the fir forty-two years; fe. 
venteen more burials therefore in one 
thoufand had been occafioned by the fmall- 
pox, fince inoculation had been adopted. 
He believes that the inoculation of the 
cow-pox fecures the perfon inoculated 
from the fimall-pox, as much as the me- 
thed of inoculation. for the fmall pox, 
with this difference, that the cow-pox is 
not infeCtious. Vaccine inoculation has 
diminifned the fatality occafioned by the 
natural {mall-pox, by Jeffening the number 
fulceptibie of taking it. Taking London 
and the out-parifhes as containing nearly 
1,c00,c00 of people, he calculates, that 
goco probably died yearly by the fmall- 
pox, or eight every day; cr allowing 
Great Britain and Ireland to contain 
12,000,000 of people, no lefs than 36,000 
annually. About eight perfons die by 
the fimal!-pox every day ia the metropelis 
and ts eAvirons, or about filty-fix in cach 
week 5 although, from fome deiects in 
the B lls cf Mortality, the amount does 
not appear to have exceeded forty five. 
But it he calculated the Jaf&{ three weeks

five deaths, and compared them with three 
weeks in March for ten years preceding, 
which amounted to 697, it would -refult 
that the prefent month was thirty-five 
lefs than the average of ten preceding 
years, that is, from 1790 to 1800. He — 
thought that the genuine cow pox was 
never fatal; he had reafon to conclade 
that about heinds perfons had been moeu- 
lated with cow pox. He had heard cur- 
forily of four deaths; but upon minute - 
inquiry, he was convinced that three of 
them had no connection with the cow- 
pox: of the fourth, he had recetved no 
accurate infurmation. Burt fuppoting the 
cow-pox, during its progrefs, to occa y. 
fourteen days, it appeared by the deatns 
in London, that. on a common average, 
in every 60,000 healthy fubjects, feven 
died in fuurteen days, without the inflic- 
tien of any difeates but what was in the 
common courte of events 5 that knowing 
the fatality of fmail pox, and rifk occa- 
fioned by inoculation, he was early inqui- 
fitive ‘upon this imporiant fulsject, both 
from its conjequence to mankind m gene- 
ral, and from bis acquaintance with fome 
particalar families, wo had fuffered both 
from the natural fmall pox and inocula- 
tion; and from tho!e who had adopied the 
practice, no one unfavourable event fas 
refulted. Hence he acquired the meft 
favourable opinion of tbe practice, which 
his {ublequent experience has not altered: 
that he had not known any inconvemences 
to follow the fpurivus iort of cow-pox. 
He further fated, that if Dr. Jenner had 
kept this pratiice a fecret to humfelf, he 
might have derived ummenfe pecumary 
profi: s; and that conlidering the apparent 
incredibility of the pra&ice to common 
obfervation, and the fewccy with which 
the Suttonians jong monopolized the in- 
oculation of {mali-pox, that D-. Jenner 
might have exclufively Kept tie practice 
to himielt for a tong period, . Upon being 
afked, Whether he had ever known a pa- 
tient who bad been inoculated for the — 
fmall- pox, undergo that, difeale a fecond 
time? he replied, that he had two rela- 
tions inoculated un ier the Suttonian me 
thod, both ef whom afterwards teak, sie 
bof pox ina natural way, one of whom 
died; and leis than twelve mouths ago, 
he had aitenced two caudren in diltieratl 
families, the parents of which aflared bim 
that they bad been inoculated fer the 
{mall pox a year or two before iis attend 
ance, when both were attacked feverely 
with the natural {ma!J-pox. He adited,
