<M. VLOERS, of Aatwerp, who his 
been bhnd for the latt twenty years, has 
invented. a language for telegraphic com- 
maunication, by which perfons unable to 
gead and write, may be infruSted in the 
fecrets of the art. He informs us, that 
with telegraphs, fixed at the difance of a 
Feagwe trom each other, he can tran{mit 
intelligence from Antwerp to Rome in 18 
minutes. 
. M. Tommast, 2 Neapolitan chemift of 
fome celebrity, who has been feveral years 
at Paris, has lately made many experi- 
ments to prove the power of the muriat of 
foda, or kitchen-falt, in deitroying the 
Jeng white worms which are found in the 
imiteftinal canal. When he put thofe 
worms into a folution of an ounce of falt 
in fifty ounces of water, they did not live 
more than 24 minutes; but when the fame 
quantity was diffolved in eight ounces of 
water, they lived only. eight minutes.

The ELector of Bavaria has given 
orders for the erection of an Obfervatory

Profeffor Parror, of Paris, has in- 
vented a filtering-machine, which purifies 
water by defcent and afcent. It confifts 
ch efly of a curved tube, one of whofe 
Jegs is longer than the other. The tube 
is to be filled to a certain height with fine 
pure fand: the water to be purified is te 
be put into the longer leg ; and it will, of 
courfe, flow out of the fherter ; and, in 
its paflage through the fand, the impuri- 
ties will be left behind. 
BauperR, commiffary of machines, at 
Munich, has conftructed an hydraulic ma- 
chine in the Eleétor’s gardens, by means 
of which the water, without having been 
pumped into a tower or railed refervoir, 
is at once forced through iron tubes to 
the height of 76 feet. The machine plays 
with facility, and its effect has been much 
admired.

M. COTEAULT, profeflor of phyfic, 
at, Poiétiers, has invented the model ofa 
very Ingenious machine, to be reforred to 
in ca‘es of fire. This machine confifts of 
fix iquare cates entering into one another, 
and which, by means of the neceflary 
cordage and leavers, can unfold like the 
different pieces of a telefcope, and rife itt 
lefs than 75 feconds, from the height of 
14 feetto that of 69. The whole is fup- 
ported upon 4 wheels that mayve in every 
direGtion, which gives the machine a great 
facility for carriage, and a great degree of 
fixednefs, when the wheels are moved in 
oppofite directions. The whole workin 
of it only takes up about 2 minutes 3 th 
fummit of the machine carries an horizon- 
tal moveable leaver, and is fufceptible of 
being lengthened or fhortened, as occafion 
lay require ; it is provided with different 
fteps for the defcent of perfons and effects, 
as by acrane. The model is large enough 
to enable any perion to afcertain its effica- 
cy ; and appears to fulfil all the-condi- 
tions required in a competition for a prize, 
fometime ago propofed, by the National 
Inftitute, although it was not finifhed by 
the time fixed ; and no prize has been ever 
yet adjudged. The fame profeffor, equal- 
ly active and ingenious, has brought to 
great perfeétion the hydraulic machines, of 
which his city, fituated upon a height, 
ftands in fogreat need. He has, likewife, 
inverted an ceconomical furnace or oven, 
and for which he is now {eliciting a patent 5 — 
and with which he gave, fometime ago, an 
excellent and abundant dinner to 22 perfons, 
conluming only 20 pounds of fagot wood, 
and 3pounds of charcoal. Hemak<s daily 
ufe of itin his kitchen, and has eftablifhed 
by means of it, an ceconomy almoft incre- 
dible ; fo that the charges of the eftablifh- 
ment are reimburfed, in a very little time. 
Dr. KEUTSCH, a very able phyfician, 
refident in the Danifh Iflands of Santa 
Cruz and St. Thomas, in the Weft In- 
dies, has lately difcovered a new method, 
and bitherto very fuccefsful, of treating 
the fevers of thole Iflands, fo fatal to Eu- 
ropeans. His procefs confifts in fri€ticns 
by oils. The firft idea of this he has de- 
rived from the theory of Dr. Scheel, of 
Copenhagen, on the ule of oil in the 
plague.—A theory which is to be found 
printed in the Work of Baldwyn. Of 
eight foldiers that were entrufted to the 
care of Dr. Keutfch, fix were happily de- 
livered from the fever, at the end of 24 
hours, by means of thefe frigtions. They
