‘¢ The operation ouzht to be begun on the 
appearance of the farft fymptoms of the difeafe ; 
if neglected till the nerves, anc the mafs of the 
blood are affected, ora diarrnza has commenced, 
little hopes can be entertained of cure; but fill 
the patient fhould not be cefpaired of, as by an 
afiduous application of the means propofed, 
fome few’ have been recovered, even after the 
diarrhea bad commenced, 
«* During the firft-four or five days, the pa- 
tient mutt obierve a very ab/iemlous diet: the 
author allows only a fmail quantity of Vermi- 
celli, fimply boiles in water. Nor. muft any 
thing be taken for the {pace of thirty or forty 
days except very light food: as he fays an in- 
digetion in any ftage of the duorder might be 
extremely dangerous. He does not allow the 
ufe of wine till the expiration of forty days. 
_ & There is no inftance of the perfon rubbing a 
patient having taken the infection ; he fhould 
previoufly anoint himfelf all over with oil, and 
muft avoid receiving the breath of the infected 
perfen into his own mouth of noftrils. The 
prevention to be ufed in all circumftances, is 
that of carefully anointing the body, and living 
upon light and eafy digefiible food. 
«© One of the many ingenious obfervations | 
made by Mr. Baldwin is, that amongft upwards 
of a million of inhabitants carried off by the 
plague in Upper and Lower Egypt, during the 
tpace of four years, he could not difcover a fingle

Among the eftablifhments in Paris, 
which concur towards the advancement 
of the fciences and the arts, one has been 
recently fet.on foot in the Champs-éy/ces. 
(elyfian fields) under the title of Ely/runr, 
which is devoted to the arts, the mufes, 
and the graces, and which opened its 
winter meetings on the 22nd of Odtober 
jaft. The literary affemblies are held 
three times in each decade (ten days) 
and the following fubjeéts have been, and 
are to be, treated ot fuceelfively during 
fix months, reckoning from that day : 
Firft, a courfe of ftatittics. Next, a courfe 
of the aftronomical part of elementary 
cofmography. Next, acourfe of Jdelles- 
lettres, fo far as they relate to the fine 
arts; together with the phyfical and mo- 
ral refources they hold out in domeftic 
life, and their influence on the relations 
of nations. Next, a courfe of theoretical 
and pra¢tical harmony, or of the nautical 
language, reduced to the principles, of 
grammar, fyntax, and poetry. ie 
laftly, a courfe of technology, and of the 
influence of the mechanical arts on the 
activity and advancement of commerce. 
This efiablifhment has a library, and a 
cabinet fet apart for ftudy. Befides the 
above courfes of leétures, there are, in 
each decade, a morning concert of ama- 
teurs, an evening concert of profeifors, 
and a drefs ball.

LALANDE, the French aftronomer, 
has received advices from his affociate, 
Beauchamp, who arrived at Trebizonde — 
on the 26th of June, of the prefent year, 
and reached Conftantinople on his return 
on the 4th of September. He ftates to 
-him that he has furveyed the principal 
points of the Black Sea, which the fgno- 
rance of the Turks and the jealoufy of 
the Ruifians had hitherto covered with 4 
thick veil. He has found the latitude of 
Sinope to be 42 degrees 2 minutes, 
inftead of 41 degrees as it has been laid 
down in the beft charts; infomuch that 
the breadth of the Black Sea, between the 
Capes Karadzé and Indgé, which was 
thought to he 62 leagues, is 37 only. So 
confiderable an error was we'l deferving 
the atrention and the labour of fo zealous 
an aftronomer. Beauchamp was to fet 
out on the 2zoth of Oftober, for Bagdad, 
from whence he was to proceed to Maf- 
cate, in Arabia, where he has the ap- 
pointment of Conful. : 
Three bread-fruit trees have been 
lately brought in the French frigate, La 
Cybele, from the Ifle of France, io 
Rochefort, from whence they are to, be 
conveyed, in afufpended carriage, to the 
Mufeum of Natural Hiftory, at Paris. 
Thefe trees were procured at the 
Friendly Iflands, by the fquadron com- 
manded by M. d’Entrecafteau, and were 
planted at Batavia, where they flotrifhed 
for feveral years, prior to their removal te 
the Ifle of France. 
M. Nort has publifhed a very learn- 
ed differtation on the art of curing her- 
rings; in which he proves that this in- 
vention was known upwards of two cen= 
turies prior tol|G. BEUKELZ, whom the ~ 
Dutch reprefent as the original inventer. 
A very interefling memoir was lately 
‘read in the National Inftitute, at Paris, by 
-citizen BENepicT PREVOST, concern- 
ing the different methods of rendering 
the emanations of odoriferous bodies per- 
ceptible to the eye. This memoir cen+ 
tains a multitude of experiments, from 
which we feleét the following : If the 
fragment of any ftrongly odomferous 
body be placed in a glafs, and covered 
with pure water, the water will inflantly 
recede and leave a dry circular {pace 
round the odoriferous body. Again, if 
any odoriferous body be placed on the fuar- 
face of pure clear water, ic will acquire a 
very rapid motion. This experiment 
was madé with camphor, by M. Ro- 
MIEU, who attributes the effeét to elec- 
tricity ; but citizen Prevost has thown, 
that it is common te all odoriferous bo-
