dies are, with regard to the time they laf, 
the moft economical ; that tallow candles, 
provided the wicks be in proportion to 
the tallow, burn the flower the fmaller 
they are, becaufe in larger ones a creater 
quantity of the fubflance is waited in 
burning; the oxygen cannot aét upon the 
whole flame ; and the encreafed heat*dif- 
perfes the combuftible matter in vapour, 
without decompofing the air, which would 
augment the light; thet fpermaceti can- 
dies are fubjeé&t to the greateft wafte of 
any, and emit more fmoke than tallow 
candles, although their vapour caufes no 
difagreeable fmell like them. He farther 
obterves, that thofe candles would be the 
brighteft, and afford the ‘molt pleafant 
light, ‘which, initead of a round, were 
made with a broad flat wick, or rather in 
the form of a hollow cylinder, that the air 
might aét upon the flame both internally 
and externally*.

of Bourdeaux a mummy found in one of 
the caverns at the bottom of the Peak of

The effeét of Galvanifm in curing deaf- 
nefs has been fully confirmed at Jever, as 
appears by the late: Numbers of the Me- 
dical and Phyfical Journal. M. Scuavs, 
apothecary, at Caffel, has cured a perfon 
who had been deaf for eighteen years by 
three weeks ufe of the Voltaic pile. 
Mark Friscuesen, Profeffor of Philo- 
fophy at Salzburg, has performed a num- 
ber of cures on the blind, lame, and 
deaf, by means of a pile confifting of 
300 plates.

A work has lately’ appeared ‘in Paris, 
tranflated from the Englith, entitled E/aé 
fur le Gouvernement de Rome; or, an Ef- 
fay on the Government of Rome, byWat- 
TER Moyte. The French journalitts 
feem to confider the immortal work of 
Montefquieu, entitled Caufes de la Gran- 
deur des Romaines, et de leur Decadence, 
(of which D’ Alembert faid jufly, that it 
might be called the Roman Hiftory for 
the Ufe of Philofophers and Statefmen, 
and which thefe authors equally applytothe 
action of fire is

and that he derived from Walter Moylé 
the principal ideas that in his own freatife 
develope hiftorically ‘and philofophically 
the caufes of the rife and downfall of the 
Roman Empiie. That chef dauvre of 
its illuftrious authof did ‘not ‘appear till 
1734, whereas the Valuable’ Effay on’ the 
Government’ of Rome, as it is modeftly 
called, was printed at London in'1726,

no mean eulogium for a work to have

this eulogium is merited by the Effay that 
Walter Moyle publifhed at London, in ~

Dr. ACHARD has juft publifhed at Ber 
lin the refults of the fecond ‘experiment, 
on a large fcale, which he has made of 
the compofition of fugar with betteraves, 
under the eyes of the commiflion appoint- 
ed fer that purpofe by the King of Pruoffia. _ 
Fifteen hundred quintals of red beet have 
produced 5952 pounds of fugar in grofs, 
4.50 quintals of hufky or expreffed matter, 
and 100 ounces of fyrup. ‘Thirty quin- 
tals of beet,cultivated agreeably to his plan, 
have furnifhed each fix pounds three’ounces 
of fugar in grofs, The {queezed fubftances 
may ferve as a fort of coffee, and for dif-

the feeding of cattle than the beets them-
