A mechanic of Copenhagen has made a 
Model of a Praam, intended to conduct 
without danger, fhips of the largeft dimen- 
fions acrofs the ice. The model has been 
examined by the moft celebrated engineers 
en the continent, and promifes to be of 
great fervice to the Danifh marine. 
Profefior Trescuow, of Copenhagen, 
has been occupied during the prejent win- 
ter, in a courle of leétures on Anthbropo- 
Jogy, in which he’ nas feverely criticifed 
the {peculations of Dr, Gall. 
A fubfeription has been opened at Ra- 
tifbon, for a Monument to the memory of 
KEPLER the altronomer. It is to confift 
of a doric temple, 23 feet high, and is to 
be erected in the Sternbergian Gardens. 
Some members of the Galvanic Society 
at Paris, have aicertained that the gal- 
vanic ation is augmented, 1. When the 
pile is expofed to a high temperature; 2. 
When it is plunged into flame, or in oxy- 
gen gas, or carbonic acid gas; 3. ‘That 
the effels of the pile are not trantmiffible 
in vacuo, or that they are then fcarcely 
perceptible, even by means of a condenf<r. 
It has been allo afcertained that galvaniiin 
cannot be tran{mitted through {moke. 
The Diamond, wiich modern chemilts 
regard as pure carbon, is, according to the 
experiments of M. BruGNAaTELLI, a 
non-conduétor of galvanifm, though it hes 
been proved that the oxide of carbon is 
one of the beft conduStors of it. 
M. Herman, of Berlin, has examined 
the properties of different fubftances em- 
ployed as Galvanic Conduétors, and has 
divided them into infulated bodies, into 
perfect and imperfe& conductors, and into 
uni-polar, and bi-polar bodies, according 
as their conduéting psoperty manifefts it- 
felf at both, or only at one of the extremi- 
ties of the pile. 
The compofition of Muriatic Acid is 
frill a fubjeét of difpute; there are in our

for both fides of the quettion, and each

The following fact is charateriftic of 
the prefent {tate of literature in France. 
A celebrated and favourite French author 
has tranflated Roscog’s Life of Leo X. 
yet notwithftanding he has taken much 
pains for fix months, be cannot find a 
bookteller willing to undertake the pub- 
lication of it. “ 
The Economical Society efablifhed o 
the Bahama Iflands, which has merited 
well of their fellow-citizens by the prizes 
propofed by them for the promotion of in- 
duftry, has obtained from the Evglifth Go. 
vernment a hundred acres of land near 
the town of Naffau, on the ifland of New 
Providence, for a betanie garden. 
M. CoLter Descorits, of Paris, 
having repeated the experiment of Mr. 
Wollaften on platina, with the fame re- 
fults, has prefented to the National Initi- 
tute a {mall quantity of rhodium and pal. 
ladium obtained from that mineral. 
Some further details have been pub- 
lifhed relative to the excavations and re- 
fearches made at Poeltum, the ancient 
Pofidonia, under the fuperintendence off 
M. Nicotar; who had been ordered by 
the Neapolitan Government to reitore the 
largelt of the three temples at Poeftum. 
One of the columns was in danger of be- 
ing thrown down by frequent fhocks of 
earthquakes, but the total ruin of this 
mott precious remains of antiquity has 
been prevented by his judicious manner 
of repairing and propping it. The rub- 
bifh having been removed, a great num- 
ber of rare and curious articles have been 
difcovered, fuch as Eirufcan vafes, cm- 
rafies, pateras, bronze and ivory cande. 
labres, &c. They intend to publifh an 
exact defcription of each of theie articles, 
which cannet fail to prove highly intereft. 
ing and ‘ufeful to antiquaries and the 
cultivators of the fine arts. We may in 
particularly notice, inthis point of view, 
an Birufcan vale, which, without any 
thing extraordinary either in form or fize, 
muit be contidered as one of the moft cu. 
rious of that kind of antiques, on 
account of the Greek infcriptions, which 
indicate not only the names af the my- 
thological figures reprefented on the vase, 
but likewife of the painter; a circum- 
Lance which renders it of very great va- 
Jue, and whichis rarely found ta fuch 
works. 
The Neapolitan Gevernment had like- 
wife ordered the reftoration of the cele- 
brated Temple of Serapis at Puzzolant, 
and other admired monuments at Reggio, 
on the coalt of Milena, Baiz, &c.
