ORIGINAL COMMUNICATIONS. 
To the Editor of the Month Magazine. 
SIR, 
AVING been lately pretty much in 
Glocefterfhire I was naturally led 
to make enquiries concerning the origin 
of the cow-pox. From the unaffected and 
uninterefted communications of the dairy- 
men I have not much doubt but that it is 
the fmall-pox moderated by  paffing 
through the purer medium of a quadru- 
ped. I generally found that a fhort time 
before the difeafe’ appeared. among the 
cows, the {mall-pox had been in the fami- 
ly; and that wherever the fimall-pox 
ceafes to appear for a long time, the cow- 
pox is not heard of. . 
This has twice happened in my father’s 
family. When his children were inocu- 
lated, the milk-maid was inoculated alfo. 
Shortly afterwards the cows were affected, 
Some time after, another milk-maid 
caught the {mall-pox, and in amonth the 
difeafe appeared among the cows. At 
‘no other time has it been among his 
cows, and at no other time has the imall- 
pox been in the family. 
That this may be more clearly afcer- 
tained, I have directed a cow to be 'mo- 
culated with variolous matter: if it pro- 
duce any fuppurative eruption, I will then 
inoculate a child with the vaccine matter, 
and communicate the refult. 
If this be the cafe, may not the cow- 
pox, by paffing through the human fub- 
ject too frequently, degenerate at laft into 
its original difeafe, the {mall-pox ? And 
fhould not this direét the practitioner to 
have recourfe as often as poflible to ge- 
nuine vaccine matter ? 
tam honoured by the polite mention 
your correfpondent R. H. C. has made of 
my intended tranflation of the ‘* Sy/fema 
Nature.’ Ydoubtlefs mean to reftore to 
their original claffes the ‘‘ Icofandria’’ and 
“© Polyaudria ;** and have hefitated whe- 
ther, with Wildenow, the whole arrange- 
ment fhould not return to the claflification 
of Linné himéelf. 
Any communications direéted to me 
concerning new difcoveries in any de- 
MontTuiy Maa. No. xLv1. 
partment, the correCtion of errors, or the 
more clearly alcertaining indiftin& fpe- 
cies, fhall be thankfully acknowledged.

. Lo the Editor of the Monthly Magazine, 
SIR, 
HAT Thetis has been adopted by 
French writers for Tethys, confirms 
the remark of.a corre{pondent who has 
honoured me with a letter on the fubject, 
re{pecting the probability that fiom like 
pronunciation they would be printed in. 
diferiminately at a French prefs. 
‘Two paflages. of a writer of confider- 
able learning and of exquifite tafe will

“Les heures chez Vhetis. ont. conduit

In both Tetdys would have been proper. 
This explains, but will mot juftify the 
fulftitution of the one for the other in 
VirGiL. Inthe French it affects neither 
the pronunciation nor the profody. In the 
Latin the pronunciation was entirely. dif- 
ferent ; and the profedy by the change be- 
comes zzadmifible. In the Latim the my- 
thological impropriety would have been 
glaring, if even the word had been admif- 
fible in the verfe of the Georgics. Butin a 
French tranflation, even of this very line, 
time and habit would have foftened the my- 
thological unexaétnels : and as Thetis isa 
marine godde([s, though fo much fubordi- 
nate, and we hear of her much oftener, her 
name for Tethys would have been paffable, 
though far from juft. 
On examination, one of my fuppofed 
errata in Didot difappears. ‘The verfe at 
the head of each page, exprefles not the 
firft verie of that page, but the laft of the 
preceding carried over: fo that the num- 
bering of the 2d £neid is right. Yet
