¥accine inoculation to introduce or excite 
any other difeafe ; on the contrary, chil- 
dren in a weak ftate of health have im- 
mediately, after paffling through the vac- 
cine inoculation, begun to thrive and be- 
came vigorous. He is of opinion, that 
the {purious or imperfeé&t fort is eafily dif- 
tinguifhable from the perfect difeafe, and 
that perfonswho have once feen the true cow 
pox puftule can never be miftaken. (No.9.) 
_. Mr. JOHN GRIFFITHS, Surgeon to the 
Queen’s Houfehold, and to St. George’s 
Hofpital, bas inoculated upwards of fif- 
teen hundred perfons with vaccine-matter, 
not one of whom has had any untoward 
{ymptom ; among them three of his own 
chiluren, at various periods, within three 
years. (No. 10.) 
Dr. Skey, Phyfician to the Worcefter 
Infirmary, ftated, That in the {pring of 
laft year, the fmall pox being generally 
and fatally epidemic in the city of Wor- 
cefter, he feized the opportunity of inocu- 
lating a number of children with the cow- 
pox ; that in the diftric&t where he inocu- 
culated the greateft number, the fmall- 
pox contagion ceafed to exert its influence, 
and the number of viétims gradually di- 
minifhed ; that in every cafe which he wit- 
mefled, the inoculated cow-pox was in- 
comparably lefs fevere than the natural 
fmall-pox ; that none of thofe patients 
whom he inoculated with vaccine-matter, 
received the fimall-pox afterwards, although 
they were conftantly expofed to the fmall- 
pox contagion, and altho’ cafes of the two 
dileafes not unfrequently occurred under 
the {ame roof, and at the faine time ; that 
he had never yet known a cafe in which 
any confiderable degree of hazard was in- 
curred by the vaccine-difeafe, and that he 
had net met witha fingle in{tance in which, 
after a fecond or third ingcuiation, he did 
not fucceed in producing the vaccine-dif- 
cafe. (No. 14.) 
Dr.Crorr has paid particular attention 
to vaccine inoculation ever fince its firft 
introduction ; from that time his own 
children have been inoculated with it, and 
he has uniformly recommended it to h.s 
patients ; he has even recommended infants 
to be inoculated at the end of the month, 
but he never dared to recommend the in- 
oculation of the fmall-pox earlier than at 
two years of age, except under very par- 
ticular circumitances. Upon being de- 
fired to relate what he knew concerning 
the inoculation of a child of Sir George 
Dallas, he ftated, that he recolle&ted a 
child of Sir George Dallas’s being inocu- 
lated with the vaccine-difeafe by Dr. Jen- 
ner ; he believed, in five days from the 
imé it was inoculated, it broke out with 
Report of the Committee on Dr. Jenner's Petition.

the fmall-pox ; it went through the dif- 
eafe rather favourably ; he was not called 
in to the child till about the third or fourth 
day of the eruption of the fmall-pox, 
when the arm inoculated appeared in the 
ftate one fhould naturally expeét to find it 
from the fifth to the feventh day. He 
imagined that the inoculation of this child 
with the vaccine-matter might have fome 
effect in abating the violence of the natu- 
ral fmall-pox, the eruption not being 
equal to what might have been expe&ted 
‘from the violence of the firft attack of 
fmall-pox fever. Sir George Dailas has 
fince had an infant of one month old in- 
oculated with the vaccine-difeafe. He had 
feen children, whofe arms had been confi- 
derably inflamed from being inoculated 
with matter taken from under the vaccine- 
{cab as late as the fourteenth day, but 
does not know why this fhould be called 
a {purious fort of cow-pox, as they had 
none of the characters of vaccine-difeafe. 
He is of opinion, that if the vaccine-in- 
oculation were generally introduced, it 
would be produttive of greater‘bleffings 
on mankind than any difcovery that was 
ever made in medicine, and it would ulti- 
mately caufe the {mall-pox on'y to be re- 
membered by name. (No. 15.) 
Mr. JAMES SiMPSOn, Surgeon to the 
Surry Difpenfary, and to the Magdalen 
Hofpital, has praétifed vaccine-inocula- 
tion, and has inoculated between fifty and 
fixty patients, and in no one inftance had 
any fymptoms occurred injurious to the 
part inoculated, .or conftitution of the 
patients ; and he believes them to be com- 
pletely fecure from the fmall-pox. In 
one particular inftance, the patient, a 
child of nine months, was covered with a 
cruft commonly called the cruffa la&ea, 
which generally covers the body from head ~ 
to foot, and had refifted the ufual reme- 
dies for that difeafe: but on the tenth day 
after the infection it began to difappear, 
and on the twelfth day was wholly gone, 
during which time not a particle of medi- 
cine was given to it; and it continued in 
perfect healthever fince. (No. 16.) - 
Many other perfons of the firft refpec- 
tability, gave evidence to the fame etfeé 
as thefe we have felef&ted; and Dr. Jenner 
aflured the Committee, that he was pre- 
pared to produce any number they might 
choofe to examine. ‘They informed him, 
that he had eftablifhed the allegations con- 
tained in his petition to their intire fatis- 
faction. And it does not appear that any 
member of the houfe, when the report was 
taken into confideration, entertained the 
{malleft doubt of the Petitioner’s claim on 
the munificence of his country.
