Some phyficians of Paris have made 
fuccefstul experiments of the refpiration 
of gas, according to the method of Dr. 
Beppors; and have founded an efta- 
blihhment in that city, for the treatment 
of patients. 
MauMup EFFENDI, the late fecretary 
of the Turkifh ambaffador at the court of 
Great Britain, has publifned a French 
tranflation of the lateft financial and mili- 
tary regulations of the prefent Emperor. 
This work has been printed at Conftanti- 
nople, in the imperial printing-office, and 
is embelhifhed with feveral plates. This 
is the firtt Turkifh production of its kind, 
and a phenamengn in the Ottoman em- 
ire. 
: M. Majo, of Noffen, near Freiburg in 
Saxony, has difcovered a durable and beau- 
tiful green, which he calls zew apple green. 
This green will admit of a confiderable 
alloy, and may be ufed either as an oil or 
water-colour. 
Dr. PrigsTLey has juft publifhed, at 
Northumberland, a work, entitled, ** The 
Doétrine of Phlogifion eftaclifhed, and that 
of the Compofition of Water refuted.’ ‘This 
work contains all that Dr. Prieftley has 
hitherto publifhed on this controverted 
point, with confiderable additions. On 
this and another fubjeét Dr. Prieftley has 
lately addrefled the following letter to one 
of the editors of the New York Medical . 
Repofitory.

' DEAR SiR, 
I fend you an extra& from a letter juft re- 
ceived from my fon in England, thinking it 
will gratify yourfelf, and the readers of the 
Medical Repofitory. 
<< Mr, Watt defired me to tell my father, 
that he has completely got the better of his 
afthma, by breathing dephlogifticated air, and 
he is in much better health in every refpect. 
They are adminiftering dephlogiflicated: nitrous 
air to twe paralytic patients, one of whom is 
nearly cured. It excites the nervous fyftem 
in a wonderful manner. Some that tale it are 
thrown into fits of laughter, others into the 
moft antic geftures, aftecting them much in 
the fame way as if they were intoxicated, and 
in fome it produces a ftate of infenfibility.” 
I have now in the prefs a work which I 
venture to entitle, ‘The Doé?rine of Phlogifton 
éfablifbed, and that of the Compofition of Water 
refuted. It: contains all that I have hitherto 
publifhed on the fubjeét, with confiderable 
addittuns. In this I may be faid, in the lan- 
guage of the prefent war, to have made an 
attack on the whole line of my opponents. As 
this war will probably laft longer than thaz 
in Europe, lam glad to find my antagonifts in 
fuch cool, good temper, efpecially Dr. Mac- 
lean, whofe feelings I am forry to feem ta 
have hurt, though I think he gave the occa- 
fion. In candour and civility I will endea- 
vour not to be exceeded by any perfon. 
Truth is, or ought to be, our common and 
only objet. Your’ Repofitory is the theatre 
of the conteft, and I hope it will not be dif- 
graced by the illiberality of any writer in it. 
With much refpe&, I am, dear Sir, yours 
fincerely, je PRIEST LE ve

The Connecticut Acidemy are endea- 
vouring to collect and preferve, for publi- 
cation, a regular feries of facts, re{pecting 
the following phenomena of nature: the 
variations of the thermometer and baro- 
meter ; extraordinary changes of weather, 
and ftorms of all kinds; ftate of the fea- 
fons: unufual tides; celeftial appearances 5 
earthquakes; unufual numbers of infects 5 
commencement, progre({s, and termination 
of epidemic difeafes among men and other 
animals; and other remarkable phyfical 
phenomena—noting, in all cafes, the pre- 
cife time when any extraordinary occur- 
rence begins and ends. 
Profeflor Meics, who began the feries 
of obfervations onthe firft day of January, 
1800, at New-Haven, notes the indication 
of the quickfilver in the thermometer thrice 
a day, at fun-rife, at two o'clock after- 
noon, and at fun-fet; the firlt being the 
coldeft, the fecond the warmeit, and the 
third the mean temperature of the natural 
day. A blank leaf is left in the book after 
each day, for the purpofe of entering here~ 
after, in its place, any fingular or memo-= 
rable events in any part of the earth, how- 
ever diftant: fuch as earthquakes, volca- 
nic eruptions, great tempeits, or other at- 
mofpherical commotions—local or general 
ficknefs among the human f{pecies or brute 
animals, the multiplication of infe&ts and 
reptiles, the prevalence of drought, the 
occurrence of hail, and all other phylical 
appearances. 
A. fteelyard has been invented by Mr. 
Benya. DearpBorn, of Maflachufetts, in 
which the centre of motion, centre of gra- 
vity, and points of {ufpenfion, are fo ad- 
jufted, that the beam vibrates like a {cale- 
beam, when loaded with weights in equi- 
librium, and when unloaded. He has ob- 
tained a patent for his invention, under the 
title of the ‘* Vibrating Steelyard.’’ Be- 
fides the advantages of the common fteel- 
yard, Mr. D.’s inftrument poffeffes the 
property of being ftri€tly accurate: it has 
but two hooks; never. requires to be re- 
verfed ; has the poifes adjufted to certain
