Street, Hitherto the plaster-cast has 
been valued for the facility it afforded of 
producing cheap, correct, and farthtul, 
copies ot the finest works of the chisel; 
but it possessed no other advantages: ifs 
colour wus unfavourable, it was liable to 
soil from the touch, and from dust, and 
its fragility and softness rendered it next 
to impossible to clean it, The present 
invention 1s said completely to obviate 
these disadvantages, and the subject of 
it may be regarded as an intermediate 
step hetween the plaster-cast, and the 
expensive marble, It possesses the beau- 
tiful whiteness and transparency of the 
finest statuary marble, and at the same 
time scarcely yielding to it in hardness 
and durability. It is not affected by the 
moisture of the dampest apartment; 1s 
less liable to suil, and as easily cleaned as 
inarble.

MR. JOHN CRAIGIE’S, (CRAVEN-STREET, 
2ONDON,) for an Improved Kitchen 
Fire-place, | 
Mr, Craigie’s invention, by which full 
two-thirds of the fuel now used will be 
saved, consists in the application of the 
powers of an air-furnace, to give heat 
externally, and in using sand iron, or 
ether dense bodies, to receive and retain 
such heat, to be employed for various 
useful purposes. A description of a fire- 
place upon the smallest scale, is as fol- 
lows: The toundation is of stone, or 
brick, four feet in length by two feet 
eight inches in breadth, and about 
twenty inches in height: at one end in 
the froyt is to be piaced the chimuey- 
grate, “eighteen imches wide and six 
deep. Qn the foundation, in the centre, 
at nineteen inches distant from each 
other, are to be raised two sides, in 
stone or brick, the whole length thereof, 
about eight inches in height: on these

sides is to be placed a pan, five or six 
inches deep, of cast-iron, of size to cover 
the whole, with rims to rest on the 
sides, but leaving a stnall space of about 
halfan inch vacant from each side be- 
low: the pan is to be raised above the 
basis, so as to leave an aperture through- 
out, of about an inch and a half; at the 
end of the furnace, opposite to the fire- 
grate, the aperture will terminate in a 
flue of brick, or iron, to convey the 
smoke into the chimney of the bouse, 
which flue should be furnished witha re 
gister; a plate projecting from the lower 
end of the pan, will form the top of the 
fire-place, of eighteen inches by six or 
eight; the sides will be formed of fire- 
bricks; the back made likewise of fire= 
Brick, will ascend towards the top, ina 
sloping direction under the pan, A 
frame of iron is to be placed to receive 
the door or front, which is to be about 
eighteen by sixteen, so as to cover the 
ash-pit four inches, and to be about 
twelve inches above the grate for the 
fire-place, in front ef which there should 
be an inner grate, five or six inches highs 
this door must have in the lower part of 
it, that is, at about one inch and a half 
from the bottom, a small door of about 
three inches wide by two in-depth, to 
furnish air through the ash-pit. The iron 
pan being filied with dry sand, will form 
a sand-bath, with heat sutiicient, accord. 
ing to the depth to which the vessel is 
placed in it, for all ordinary purposes ; 
and being once heated, will retain the 
heat for a considerable time, especially 
ifthe doors are kept close shut: the plate 
or front will serve for broiling or frying. 
Roasting may be performed in high per- 
fection, before the door in front, even 
with the door shut; an oven for baking 
may be fixed at the flue. In roasting, a 
fire-screen should be used. .
