vitreous substance. A strong fre must be 
esnfinuéd? in ‘ordér to’ obtain a ‘complete 
fusion if as little time as possible. When 
the funies diminish smal! portions must’ be 
teken’ out at different ‘times to’ ascertain 
whether the glass| be! sufficiently refined, 
which generally happens in about: twenty- 
two hours. ‘Thisglass is'then fit for use ; it 
may rémain double the time in the furnace 
without risk. Another mode preposed is 
to take 100 parts of well dried muriate of 
soda, 123 parts of silica, 92 parts of lime 
which has been exposed to the air, well 
mixed together and fused in the way above 
described : in sixteen hoursa good glass will 
be obtained, which will be fit for use for 
any purpose that may be required. Other 
proportionsare likewise assigned—100 dried 
muriate of soda, 100 slacked lime; 140 
sand ; from 50 to 200 clippings of glass of 
the same qnality—or 100 dried sulphate 
of soda, 12 slacked lime, 19 powdered 
charcoal, 225 sand, 50 to 200 broken glass 
—or 100 dry sulphate of soda, 266 slacked 
lime, 500 sand, 50 to 200 broken glass. —

Butter in a Boy.—A letter from the 
Viscount Dunlo, of which the following is 
aextract; was read at the meeting of the 
‘Royal® Dublin Society, June 5, 1826. 
* Tn'a bog upon an’ estate of Lord Clan- 
earty’s, ‘adjoining Ballinasloe, has” just 
been dug up'a'tub of butter, which, from 
the circumstance of the wood-work haying 
been quite rotten, so as to fall’ off when 
fouched, must be of great antiquity. It 
was this morning discovered by turf cutters 
at the depth of eight feet from the surface of 
the bog. Upon probing it with a long knife 
some hard substance was found to resist, 
in consequence of which it was cut into 
two pieces. The resistance appears to 
have arisen from a great part of it having 
become hard and dry; about one-half of it 
isin this State, the rest to all appearance 
fresh and good, and emitting no smell. 
‘Lhe two parts have been put together again, 
and at present lie in Lord Clancarty’s cellar 
at Garbally.. The marks of the tub on them 
are quite distmet.””—Annals of Philosopiry. 
‘The Burranyiouter.—The military ope- 
rations of our countrymen have led to an 
examination of the course of the Burram- 
pouter; one of the greatest rivers of A’sia, 
but of which, except the name, very little 
was known with certainty. In a’ journey; 
ef which the details have not been as yet 
eommunicated to the publie, Lieutenant 
Boulton obtained the following informa- 
tion. 
Bengal in latitude 22° 40 N., is navigable 
to 279, 54/., Nearly under) this } parallel, 
where the Ganges takes a westerly direc- 
tion, the’ Burrampouter’ tends to the east- 
ward, rutiniig’ between thé ‘mountains’ of 
Miri, Amor, and Michini, “behitid which 
many lofty chaifis “GF snowy mouittains are

upper part of its course, communicates 
with another which! discharzes itself into 
the Burrampouter; ‘offering ‘a singular ‘ex- 
ample of an island, thirty leagues? long by 
sixteen in breadth, formed bya large 'stream 
proceeding in’ different direetibns..! Tuavas 
for a long time believed, ‘and’ Majer/Ren- 
nel inclined to the opinion, ‘that the! |\Chi- 
nese maps were’ erroneous in) distinguish- 
ing the’ river of Sanpo, or of ‘Alou-Tsang- 
pore, from the Buranrpouter ; but the /ac- 
counts of the natives of all the neighbour- 
ing countries confirm the accuracy of the 
Chinese geographers. ‘They ‘aflirm’ that 
the source of the last of these rivers lies 
nearly in latitude 27° 44" and longitude 
96° 2’ from’ Greenwich; its waters issue 
from the eastern mountains, by an open- 
ing which discharges the overflowings' of a 
lake called Bramah-Khoond: It is known 
that a similar basin, which unites the waters 
from the Himalaya and the Cailas, forms 
between their lofty chains the lakes of 
Manassavouwer and Ervon-Iirad, from which 
the Sutle) and probably many other great 
rivers of Asia have their/origin’’ No Bu- 
ropean traveller ‘has’ as yet ‘approached 
nearer than six days’ journey, or from forty 
to fifty miles to the souree of the Burram- 
pouter, and at the farthest point they have 
reached ‘the channel of the river ‘has not 
been Jess than from 6 ito700) yards in 
breadth. / People very ‘different in their 
habits have been found on the ‘banks of this 
mighty stream, and among others the! Mi- 
ris, half barbarous mountaineers, whose 
language, appearance, and’ manners, have 
no resemblance to those of the inhabitants 
of Assam. They use the bow with great 
dexterity, and in the chace employ arrows 
imbued with a vegetable’ poison produced 
by a plant which grows°in) the» country, 
but the flesh of animals killed-by this poi- 
son is eaten without any ill effeets. All 
the Hindoos regard as sacred the source 
of the Burrampouter, which was formerly 
an object of pilgrimage. ©The inhabitants 
of all classes pointed out to our country- 
men the direction in which it lay, by show- 
ing them, at about fifteemleagues distance, 
a very distinct opening inthe lowest of a 
chair of mountains ‘running towards: the 
east, behind whieh, according oto their sre- 
port, is the reservoirtrom which the stream 
issues ; this is described as a circular basin 
inthe side of the nmduntains® below” the 
reaion of snow; the inaccessible summits of 
which_rise towering above it on every side.
