Mr. Epwarp TrouGuHTon has con- 
Rructed a new telefcope for determining 
the magnetical meridian. It confifts of a 
tube of fteel, containing a fet of lenfes 
with crofs wires or fpiders” wehs, in the 
ffual manner. It will be eafily underflood 
that an inftrument of this kind, a‘ter re- 
ceiving the magnetic power, may traverfe 
Upen pivots, or by any other fimilar mode 
6f fufpenfion, and will difpote itielf in the 
Magnetic meridian. One of the difficul. 
ties attending the magnetic 
ufeal form is, that its Hine of direétion 
fhay not be paraliel to its fide; and It is 
hot éafy to determine the quantity of error 
by reveriing it, becaufe this laft operation 
is in moft. cafes’ impracticablé. Mr. 
Troughton’s magnetic telefcope may be 
turned round in its fupport like that of a 
levelling inftrument, and it will deter. 
Mine thé magnetic meridian; whenever 
Shy one and the fame diftant objet is 
feen upon the centre of the crofs wires, 
after the telefeope has been turned round 
On its axis, as in its former ftate,

was prefented to Sin J. T. DuckworrTu, 
Bart., a fuperb gold fword of five -hun- 
dred guineas value, and worn by him that 
éay at St. James’s, being a prefent from 
the Houfe of Affembly at Jamaica, for 
his eminent fervices in protecting that 
land in 1804. This fword, the moft 
valuable without havifiz jewels of any 
éver made in this country, was defigned 
and executed by Mr. Teed, cf Lan-

Ruffia. 
The government of China would. not 
permit the !¢arned-men and artifts attached 
to the Ruffian embafly, to proceed into the 
interior of that-country.. One of them, 
the Councijlor af Strate, Schubat, intends 
returning by way of northern Siberia, for 
the purpoie of coilecting im a country fo 
Nittle known té Europeans every thing 
worthy of obfervation. _ - 
A.complete fkeleton’ of anelephant has 
been lately difcovered at Sbinchow, in the 
Ruffian government of Cafan. This is 
a phenomenon which confirms the conjéec- 
tures of M, Buffon. 
A judgment may bé formed of the zeal 
for the fciences in the Ruffian province of 
Kiow, from the circumftance that in three 
days the ‘um of 500,000 rubles was fub- 
fcribed for the fupport of the-coliege ef- 
tablifhed in that.city. . 
Prince BesBoropxKo has given 4 fund 
of 210,000 rubles, and a annual revenve 
of 4§;000 rubles, to the college which he

In a periodical work. publifed at Pe. 
terfburg, entirléd the “ St. Peterburgifche 
Mongqthicrift,’” there is 2 very intereiting 
article on the progrefs of fearning and ci- 
vilization in Ruffia; from the moft remote 
antiquity to the time of Pe'er the Great, 
What will particularly attraét the atten- 
tion, is the hope held out of retoveiihe 
fome of the works of the ancients fuppofed 
to be irretrievably lof#. It appears that 
Jariflaus I.; fon of Waladian the Great, 
invited to bis court a great number of 
learned Greeks, and employed them in 
tranflating into the Slavonic language 
Greek works, .the criginal of which were 
depofited. in the churth of St. Sophia. 
Conftantin’ was fo great a lover of the 
fciences, that be collefted more than yodd 
Greek manufcripts, feveral of which he 
caufed to be tranflated and diftributed to 
the fchocls im his dominions. Alexis 
Michaelowitz, wifhing to compare the 
Slavonic verfions of the beoks uféd in the 
_churehes with the originals, caufed:to ~be 
purehafed in Greece, and particularly at 
Mont Athos, about $00 MSS., which aye 
ftill preferved in the library of the fynod 
at Mofcow. Even allowing that the laft- 
mentioned colie€tion conftits of copies of 
the Holy Scriptures and of the Fathers: 
yet it may reafonably, be conjeftured that 
this was not the eafe with refpect to the 
1000 MSS. colleéied by Conitantine ; and 
it may be afkedy what is become of thofe 
prefented by hinmto the {cliools, and whe- 
ther the ftill more nameroue colleétion of 
Jariflaus I. has not remained af the church 
of St. Sophia. It is to ve hoped that alf 
the convents of Rufia will be cailed upon 
a 
to furnifh a catalogue of their libraries, ~ 
by which means we may flatter ourfelves 
to bring to light fome precious remains 
of ancient Greek literature. 
The following is the method of prepara 
ing Turkey ieather in the Crimea :— The 
fkins are firft fteeped twenty-four hours in 
cold water. - The flefhy parts and fat are 
then fcraped off. They are macerated ten 
days in lime-water, after which the hair is - 
removed ; they are then foaked for a fort- 
night in clean water, frequently seutwed 
and kneaded by treadings The laft water 
is impregnated with dog’s dung, to com- 
plete the ieparation of the hair; they are 
icraped, and then confidered as clean, — 
‘The fkins ave then foaketé four days in an 
anfuion of bran j afterwards in a luke-
