M. TiscuBein, direétor of the Royal 
Academy of Arts at Naples, has been for 
fome years colleSting at Rome and Naples, 
all the vafes, reliefs, bufts, and gems, 
and other monuments which appear to re- 
prefent fubjeéts taken from Homer. 
Thefe he has either made drawings of 
himlelf, or has had them taken by good 
artifts, and all the heads of Homer’s he- 
roes, taken from the moft celebrated bufts, 
along with the other figures, have been 
engraved in a fuperior ftyle at Naples, by 
. M. Morghen, engraver to the king. He 
has brought the whole collelion with him 
to Germany, at Caffel, where he now re- 
fides; and Profeflor Heyne has added a text 
of critical remarks to accompany them. 
RapHaEL MorRGHEN, of German ex- 
_traétion, who is confeffedly one of the bef 
engravers in Italy, now refides at Flo- 
rence, and there fuperintends an excellent 
{chool for the art, which he has eftablithed. 
The lateft work which he has publifhed is 
a print of the Laft Supper, by Leonardo 
da Vinci, a frefco painting in the refet- 
tory of the monaftery of the Dominicans /a 
Madouna delle Grezzie, at Milan. This 
chef-d euvre of the art, which unfortu- 
nately is perifhing from decay, will be 
perpetuated, in fome degree, by this ex- 
cellent engraving of Morghen which was 
taken from a copy of the original picture 
done by Theodoro Matteini, a painter at 
Florence. The proof imprefiions fold for 
30 fequins, a price which the great beauty 
of the engraving alone prevents from be- 
ing exorbitant. The other copies fell for 
10 fequins, 
The government of Hanover have pur- 
chafed for the ufe of the univerfity of 
Gottingen the aftronomical inftruments of 
Mr. Schraoter, of Lilienthal, in Bremen, 
who, however, referves the ufe of them 
during his life. 
Mr. ScHERER, who had lately been 
appointed profeflor of chemifiry to the 
univerfity of Halle, is going to Berlin, as 
fuperintendant of the chemical part of the 
porcelain manufaéture of the Barons Eck- 
artitein, with an appointment of a thou- 
fand rix-dollars a year and a houfe. 
CuapPTat has lately difcovered a new 
method of bleaching cotton by the vapour 
of fixed alkali. This has been put in 
_ practice at an eftablifhment, by C. Baw- 
ENs, who bleaches two or three thoufand 
ells of cloth daily, by ufing only thirty 
pounds of foda, and the work of one man. 
A very curious operation in furgery has 
jately been performed at Paris, by Cit. 
Literary and Philofophical Iatelli ences 53 
Demours, a celebrated optician. The 
patient had hai for feveral years fucceffive- 
ly abfcefles on the tranfparent cornea of the 
eye, in confequence of which the aqueous 
humour was entirely loft, and the cornea 
had become white and opake, entirely fo 
in the right eye, but only over five fixths 
of thelett. Theonly portion of the latter 
which remained pervious to light was on 
the upper part, and fo high as entirely to 
prevent any rays from pafling thence 
through the pupil to the retina. To re- 
medy this, the operation was conceived, 
of cutting an opening through the pupil 
oppofite to the luminous part of the cornea, 
which was accordingly performed by mak- 
ing a fimall orifice near the latter, large 
enough to introduce a very fine pair of 
{ciffars, with which a {mall flit was made 
in the iris. However, as this artificial 
pupil (which is in fact an enlargement of 
the natural) is alfo above the cryfalline 
Jens, and out of the {phere of its action, 
the patient is obliged to u'e a very convex 
glafs in order to read, as thofe perfons do 
from whom the cryftalline humour has 
been extraéted in the ufual manner; but 
this he oniyrequires when he wants to fee 
with fame accuracy, for he can walk the 
ftreets and diftinguifh common objects per- 
feStly well without affittance. 
The laf enumeration taken of the in- 
fane confined in the Bicetre, ‘amounts to 
200, of whom 22 are melancholy mad; 
15 furious, without delirium; 80 truly 
maniacal, that is, with furious or extra- 
vagant delirium, either conftant or pe- 
riodical ; 18 fimply infane; and 60 infane 
to idiotifm. : 
Dr. Auvesrt (the gentleman who was 
commiffioned from the Infiitute, at Paris, 
to examine into the merits of the Vaccine 
Inoculation, as praétifed is England) has 
lately publifhed,at Paris,an excellent treatife 
on this fubject, compofed with great care, 
written with much good fenfe, and fhewing 
a very accurate and impartial examination 
into this interefting branch of the healing 
arf. 
It zppears, that in France as well as 
here damage has been done to fome of the 
crops, efpecially the oats, by the vioient 
rains fucceeding the long feries of hot wea- 
ther. Several oat ftacks have taken fire 
owing to the neceflity of putting up wet 
thofe fheaves which were kept too long on 
the ground for the purpofe getting a lit- 
tle moifiure in order to fwell the grain, 
and makea higher return in weight to the 
farmer.
