SIR, 
BEG leave, through the medium of 
your Magazine, topoint outto Dr. Tur- 
ton how§very erroneous his opinion is re- 
f{pecting the origin of the Variolz Vaccinz, 
or Cow-Pox. If Dr. Turton had atten- 
tively read Dr. Jenner’s two publications 
upon that important fubje&t, he muft, I 
conceive, have been convinced, upon the 
cleareft evidence, that the {mall-pox is not 
the fource from whence the cow-pox 
{prings; but agree with Dr. Jenner in the 
more rational conjecture, that the latter is 
the parent of the former ; for if we examine 
the third cafe mentioned by Dr. Jenner 
in his firft publication, we fhall find the 
cdw-pox to have exifted, and to have been 
knewn, before the inoculation for the 
fmall-pox was introduced into praétice in 
this ifland. It-would be unreafonable to 
fuppofe that perfons labouring under fo 
dreadful a malady as the natural f{mall- 
pox, at a time when no means were difco- 
vered to mitigate the malignancy of the © 
difeafe, ‘fhould be employed to milk cows 
atadairy. Dr. Turton forms his opi- 
nion from the cow-pox having fwice ap- 
peared among the cows a fhort time after 
_ the fmall-pox had been in the family. It 
was fingular that it fhould fo happen; but 
thefe two folitary inftances are but a flight 
bafis to build a new hypothefis upon. 
It is poffible that variolous virus’ in- 
ferted into the nipples ef a cow might 
produce inflammation and fuppuration; 
nd that matter from fuch a fore might 
o 
produce fome local affection on the human 
fubje&t by inoculation. But all this tends 
only to fhew, what was well known be- 
fore, that virus taken from one ulcer js 
capabJe of producing another by its being 
inlerted into any other part of the body. 
With regard to the fuppofition of the 
cow-pox becoming {mall-pox after repeat- 
ed inoculations, J fhall only remark, that

through upwards of thirty perfons with. 
out the finalleft alteration either in its ap- 
pearance or effect. , 
I thould not have made any remarks on 
Dr. Turton’s letter, for I think (fo far as 
it relates to the cow-pox) it ftands felf. 
confuted, but only as I thought it calcu. 
lated to fhake the confidence of fome per- 
fons, whole care and anxiety for the pre- 
fervation of their tender offspring might 
induce them to fub{titute fo mild a difeate 
as the cow-pox, for one fo violent in its 
nature as the fmall-pox. 
The Doftor will excufe me for offering’ 
him a word of advice; which is, to be: 
cautious (as he appears to be perfeéily un- 
acquainted with the habits of the difeafe) 
not to produce a fpurious kind of cow- 
pox, and fend it abroad into’ the world 
under an idea of its being the genuine.

NE of the Monthly Magazines of 
about a year back or mere (not 
having the number by me, I cannot pre- 
cifely fay) mentioned that a colleétion of » 
Latin Poems, written by various perfons, 
natives of Scotland, was made by a clergy- 
man, with a view of convincing the world, 
that the Scots have furpafled all other’ 
nations in writing Modern Latin Poetry ; 
and which would in a fhort time be pub- 
lifhed. If any of your readers can intorm 
me whether the work is printed, or likely 
to be fo, they will oblige, Sir,

SIR, 
1) EADING the Philofophical Maga- 
! zine for laft month (July), I ob- 
ferved that Dr. Mitchell, of Philadelphia, 
fays, that in falting meat ‘a decom- 
pofition takes place in this manner: 
The feptic acid of the ‘meat unites itfelf 
with the foda of the falt; and the muriatic 
acid of the falt unites itfelf with the meat. 
Here then are two new fubftances, viz. 
Muriate of flefh (falt meat) 5 and 
Septate of foda (brine). 
And here arife two queries, whofe anfwers 
may lead to fome difcoveries uleful to {o- 
ciety. 
rit, Does this decompofition take place 
becaufe the affinity of the muriatic acid to 
the fiefh is creater than it is to the foda?

feptic
