2 
apparent conftitutional indifpofition. 
(No. 8.) 
Dr. JosEPpH MaRSHALL, Phyfician Ex- 
traordinary to the King of Naples, firit 
began to inoculate in the fummer of 1799; 
in Gloucetterfhire, having received in- 
ftruétions on this fubjeét from Dr. Jenner. 
Tn July, 1800, recommended by Dr. John 
Walker, who affifted him in fome of thefe 
inoculations, he commenced this practice 
on board his Majefty’s fhip the Endymian, 
eleven of whofe crew were inoculated, 
and went through the vaccine difeafe 
without any remiffion of their ordinary 
duty, or any deprivation of their ufual 
allowance of wine or provifions. He alfo 
inoculated fuch foldiers of the garrifon of 
Gibraltar, as had not had the fimall- 
pox; the plague, at this time, prevented 
the garrifon from receiving the ufual fup- 
plies of frefh provifions from Barbary ; 
and Spain was fhut againft them by the 
war; their food in confequence was prin- 
cipally falt provifions fent from Englart, 
and they generally indulged in drinking 
New wine; this diet, added to the ex- 
cefles which foldiers ufually commit, put 
the cow-pox to a fevere trial, efpecially 
when it is further confidered that they, 
whilft under inoculation, performed their 
ordinary regimental duties; and fo far 
was the cow-pox from preventing their 
doing this, that not a fingle cafe occurred 
where any application was requifite to the 
inoculated part, though the heat of the 
atmo{phere was frequently upwards of 
ninety degrees ; in corroboration of which 
the furgeon-major’s certificate was pro- 
duced. At Minorca the fame fuccefs at- 
tended the inoculation, where it was alfo 
generally introduced amongft the inhabi- 
tants; and their medical men were in- 
firuéted in the praétice; fuch feamen alfo 
on board of the Britith fleet, under the 
command of Admiral Lord Keith, as had 
not had the fmall-pox, were inoculated 
with the cow-pox. At Malta, its prac- 
tice was alfo generally introduced both 
among the troops and inhabitants ; and 
an hofpital, called the Jennerian Inftitu- 
tion, was eftablifhed by the governor, for 
the inoculation of the poor. In this ifland 
the ravages of the fmall-pox had always 
been dreadful; and fome of the men of 
war then in the harbour, had the {mall- 
pox on board, and had buried feveral 
men; this apprebenfion was aifo enter- 
tained: by the Admiral and General Sir 
Ralph Abercrombie, who each iffued ge- 
neral orders for the inoculation of. fuch 
feamen and foldiers, under their refpeCtive 
commands, as had not had the fmall- 
pox, A certificate, confirming the above 
Report of the Committee on Dr. Jenner's Petition, [Aug. hy 
facts, was delivered in, figned by Sir 
Alexander Ball, governor of Malta. In 
‘Sicily, the fmall-pox had been, if poffi- 
ble, ftill more fatal than in Malta; for 
the computation of deaths, occafioned by 
it in the year preceding his arrival, ex- 
ceeded eight thoufand in the cizy of Pa- 
lermo alone: the introduétion of the cow- 
pox was therefore received with enthu- 
fiafm, and an hofpital, nmilar to that a€ 
Malta, was immediately eftablifhed by his 
Sicilian Majefty ; and although the fmall- 
pox, foon after his arrival in the city, 
again appeared, it was immediately ftop- 
ped by vaccine inoculation, which was 
alfo extended through the whole ifland. 
The benefits received at Palermo trom the 
cow-pox excited a great with for its prac- 
tice in Naples, where the fmall-pox has 
always been confidered as very fatal. An 
hofpital was alfo there eftablifhed by his 
Majefty, and the praétice of vaccine- 
insculation was fpeedily adopted through- 
out the whole kingdom; His Majefty 
having commanded that children to be 
inoculated, attended by furgeons to be 
inftrusted in the praétice, thould be fent 
from each province to the hofpital ar 
Naples, to carry both the knowledge of 
the difeafz, and the practice of it into 
their refpective provinces. On his leaving 
Naples, the witnefs received very ho- 
nourable teftimonials ‘from His Sicilian. 
Majeity, which were produced. He alfo 
extended this praétice to other parts of 
Europe, to Rome, Leghorn, and Genoa, 
and in every inftance, where tried, he 
found it refift the infe€tion of fmall-pox. 
He never heard that any fuch mode of 
inoculation had been prattifed or knowa 
in thofe countries. before ; and as an ex- 
ample of the difbelief entertained by the 
medical men of Naples, he related a trial 
which they inftituted foon after his arrival 
there, and without his knowledge, at the 
Foundling Hofpital; where they firft in- 
oculated with the cow-pox.a confider- 
able number of children; and after they 
_had paffed through the difeafe, expofed: 
them to all poffible modes of infeQion of 
the {mall-pox, both by inoculation, and 
by making them fleep in the bed with 
people infeSted with the {mall-pox. This- 
trial, which had excited the attention of 
the whole city, completely eftablifhed the 
reputation of the cow-pox; and they ap- 
pointed a deputation to him, publicly to 
expre(s their conviétion of its efticacy. 
He believes the number inocalated under 
his direction was upwards of ten thouland; 
many of them were fubjeéted. to every poffi- 
ble means of variolous infeGtion, which alk 
of them refilled, He never did obferve the 
vaccine”
