plan on which it is built, taere would be 
a saving of at least one third. of the. ex- 
pence in the building of ships; that, on 
account of its being rather flat bottomed, 
it will carry more tonnaye, and will navi- 
gate invery shallow water, and over break- 
ers or sunken rocks, without the risk that a 
ship with a keel runs, as, on approaching 
a rock, or coast, it can namediately retire 
Eton loss of time in putting about. It 
does not require half the sails now used, 
all of which can be worked by the men 
on deck without going aloft. The com- 
position which covers it is much cheaper 
than copper, and, Lord Stanhope says, an- 
swers the same purpose. The vessels cai 
iso sail nearly against the wind by work- 
ing the gills. 
The spirit of mining speculation is be- 
ginning to shew itself: strongly in Ireland. 
Several cargoes of the richest copper ore 
have been sold at Swansea, this summer, 
from Ross island mine, on the lake of 
Killarne A. number of Cornish mmers 
have been spctba engaged for the pur- 
pose of working a new. copper mine on 
the estate of the Earl of Derby, near 
the town of Tipperary, which from the 
superior quality of the ore, promises con- 
siderable benefit to the country, and to 
the « adventurer. The Ross hate and 
Enniscorthy mines, have given almost 
constant employ ment to 1000 persons for 
three years past. 
RUSSIA. 
On the 13th of March last, in the af- 
ternoon, the inhabitants of the Canton of : 
Juchnow, in the government. of Smolensk, 
were alarmed by an uncommon loud clap 
of thunder. At the moment of this ex- 
plosion, two peasants belonging to the 
village of Peremeschajew, in the canton 
of Werreja, being out in the fields, per- 
ceived ai. the distance of forty paces, a 
black stone of considerable magnitude, 
falling to the earth, which it penetrated 
to a considerable depth beneath the snow. 
It was dug up, and found to be of an ob- 
long square figure of a black colour, re- 
sembling cast iron. Its surface was very 
smooth, shaped like a coffin on one side, 
and weighed about one hundred and sixty 
pounds, 
The gold mines of Russia afford 42,675 
pounds” weight of that metal annually; 
the silver mines 1,564,750 pounds, and 
the copper mines 7,000,000 pounds. The 
value of the iron annually exported from 
Rassia is about £.1,200,000 sterling.

cai of Caucasus, with inseriptions in 
the Slavic language, by which it appeared. 
that a Russian Brince; Glieh de. Lmukto- 
rakan, had caused the breadth of, the. 
Cimmerian Bosphorus to be measured in 
year 1068. On this. occasion, Count Mus- 
chin Puschin published, in 1794, “ Histo-. 
rical Researches on the Geoyraphical Si- 
tuation of Tmuktorakan.” The state 
counsellor, Alexis Niwtaj Olenin, has re-. 
cently published on the sane subject, ad=. 
dressed to the count, a letter in fifty-six. 
folio pages, with nine engravings. Among 
other things, this letter contains the de- 
scription of five manuscripts of Nestorius. 
DENMARK. 
The learned have long doubted the ex- 
-iIstence of a printing- -oilice, said to have 
been established by the cles ated astro- 
nomer Tycho Brabé, in theisland of Huen, 
or Ween, in the Sound, in. the Observa- 
tory of Uranienburgh, erected for him on 
that island by Haedone Il. of Denmark. 
The existence of this pease office is 
now proved, by the following titles of two 
works, which Tycho Brahé caused to be 
printed at Uranienburg. They are both 
in quarto, and one is entitled, “ De Mun- 
di Aetherei recentioribus Phenoiminis, 
liber secundus. Uraniburgi in Insula 
Hellesponti Danici Huena, imprimebat. 
auctoris Typographus Christephorus W ei- 
da, Anno Domini, 1588.” ‘The title of 
the other 1s “ Tychoni s. Brahé Dani Epis- 
tolarum Astronomicarum hber primus. 
Uraniburgi ex officina Vypographica auc- 
toris. Anno Domim 1596.” In the 
last work, are found many letters from. 
Tycho Brahé tothe Landgrave Willa of 
Hesse, wherein he mentions the printing 
office, and the paper mills, he had este- 
blished at Uramenburgh ; and_in the late 
ter work is an engraving on woad, of the 
house in which this printing-office was 
established. ; 
The bombardment of Copenhagen has 
produced some unhappy effects to. litera- 
ture. Besides several private libraries 
which have been destroyed, the valuable 
collection of books, which belonged. to 
Professors Risbrigh, Wolf, Kierulf, and 
Woldike, were consumed by the flames. 
Three printing offices were. destroyed, 
with several books and Pa bes : 
great value ; and, among others, Olatse 
Icelandic Dictionary, printed at hers ex 
pence of the Royal Acadewy of Sciences.
