SLATE QUARRY, NEAR CARNARVON, NORT 'll, WALES.
R. GEORGE ROBINS is instructed to DIS-
POSE OF, by PRIVATE CONTRACT, a valuable SLATE
QUARRY, in the most convenient position for readily embarking
the produce to every part, and which is held under a lease for
twenty-one years, renewable on application. It is about seven miles
from the thriving town of Carnarvon, with the advantage of a rail
or tram-road, which goes threugh the lower part of the quarry, an d
thence to that town. The quality of the slate, which is of a most
beautiful blue, cannot be surpassed; it is to be found in vast
abundance, and capable of being manufactured to any size that may
be required, A considerable part on the top has been worked,
evincing ample proof of the superiority of the produce. A short
level can easily be made, so as to have a depth of twenty-two yards
over the whole of the quarry. The length of the vein is about 300
yards, and the breadth about 130. There is every convenience and
advantage for conducting the working successfully ; and there cad
be no question a large amount of annual profit may be safely reliea
upon by the employment of only a moderate capital.
Mr. Thomas Richardson, of South Penrallt, will show the quarry
of whom full particulars may be had ; also at Mr. George Robins'S
offices, Covent-garden.

THE UNIVERSAL GAS BURNER.
34 to be per Cent. Saved !
To be had at the Patentees, 60, St. Martin's-lane, Charing-cross.
The Patentees beg to call public attention to the following facts,
The advantages resulting from the invention are various and
striking. Independently of a saving of 30 to be per cent„ the coin-
bustien is perfect, and the brilliancy produced superior to any light
hitherto discovered. It emits neither smell nor smoke, and burns
steadily for any period ; and such is its purity, that it neither affects
or soils the most delicate colour or the finest fabric. Objections have
made to the introduction of gas in dwelling-houses, to the expense of
fittings, to its destruction of furniture, draperies, gold moulding, Sec. ;
these are entirely obviated by the "PATENT UNIVERSAL Gss
BURNER." As the cost of laying on gas is muck lower than is com-
monly supposed, it is adapted for private dwellings, as well as for
club-houses, hotels, manufactories, and public buildings. One of the
small burners is amply sufficient to light a good-sized room, at a sum
immeasurably lower than spirit, oil, or candle, with the avoidance of

Extract from the Proceedings of the Institution of Civil Engineers,
Tuesday, 26th May, 1846, Sir Joi; RENNIE, President, in the Chair.
"A gas burner of a novel and ingenious construction was exhibited.
The principal novelty was the introduction of a stream of air to the
centre of the flame by a hollow button in the middle of the burner.
The air passing up through the hollow stem of the button, was
heated, and passed out by two series of fire-holes around the periphery,
and Lnpiuging with force on the flame of the gas curved it outwards
in the shape of a tulip, while the oxygen of the air, mingling with
the carburetted hydrogen gas, produced a very perfect combustion,
The flame was quite white down the top of the burner, was very steady,
as was amply demonstrated by the excellent light of the Institution,
where these burners have been used. In comparing the consumption
of these burners with that of the concentric ring burners, and trying
the power of the two lights by the photometer, the new burner gave a
better ght, with a saving of rather more than one-thlrd."

POLYTECHNIC CHEMICAL SCIIOOL.—" Ia testing Clark, McNiell,
and s Universe lGas Burner with one of the best shawdowess
burners, it gave a more pure and brilliant light, with a saving of 20

CERTIFICATE.
" In a series of experiments made upon Clark, Ms Niell, and Co.'s
Patent Universal Gas Burner, its superiority was satisfactorily esta-
blished in economy and the quality of the light. Tested against
argand burners, Nos. 4 (12 holes), and 6 (15 holes), it afforded a
saving of at least 25 per cent., and against three fish-tail burners,
No. 4,4 e per cent. The colour and brilliancy of the flame is supe-
rior to any other burner."

3. D. PALMER, Mechanical Inspector.
The WNIVERSAL GAS BURNER is used nightly at the Poly-
technic Institution, and may be had and seen from 11 till 4, at the
Patentece,69, St. Martin's-lane, Charing-cross; and of all Gas Fitters.
