CoLoRING SroNE.-The London Artis-
an says that building stone may be tinted
in different shades by impregnating it
with metallic salts, and then adding a.
precipitating re-agent. By means of salts
of lead and copper, with sulphurated hy-
drogen, grays, browns and blacks may
be produced. Copper and ferroaganide
potassium give red tint. If porous
limestones are boiled in solution of metal
lie sulphate, carbonic acid is evolved, and
the metallic oxyd, combined with sui.
plate of lime, is deeply fixed in stone
In this manner, sulphate of iron gives
rusty tints. sulphate of copper fine green
sulphate of fmagnanse brown, and mix
ed sulphates of iron and copper, choco-
late. The double sulphates thus formed
increase the hardnes of the stone.
New TEXTILE FABRIc.-A method has
been devised for making cloth or fabric
which has the appearance being partly
Grape and partly Orleans cloth. To eff
feet this. the warp of the fabric is made
of worsted or other suitable yarn, and a
weft of woolen yarn used for some parts,
and OF worsted yarn for other parts. the
different qualities of weft producing a
different cloth in the same web. A great
variety of fabrics may thus be produced
in one web of cloth, for various uses, by
the use of alpaca, mohair, silk and other
weft.
BRITISH PoRcELA1N.-At arecent meet
ing of the Burslem School of Design, in
Staffordshire, England, Mr.. H. Mintom
made speech, ir which he stated that in
the manufacture of china and earthen-
ware, England surpassed France, but
great efforts were required to maintain
their present position. 1t is singular
fact that the British porcelain manufac.
ture may be said to be the product of one
ingenious working man, and he leme and
enfeebled-the well known Wedgewood,
who as journeyman potter, elevated the
porcelain manufacture of England from
a rude to a most elegant art, and was cre-
ated member of the Royal Society.
IMPROVED WEIGHING ScALEs.-By a
recent invention, instead of one arm or
lever as employed in ordinary weighing
three arms are provided, with
a weight upon each. This arrangement
permits the permanent attachments of the
weights to the arm, and thus prevents
the inconvenience that often occu, from
the lower misplacing Of the weights. It
also affords great convenience in ascer-
tanning the tare of the article, for one of
the weights may be moved so as to indi-
cate the tare, while another will show
the gross sum.
MACHINE FOR PEGG1Na Doors AND
SHoEs.-A new machine for this purpose
has been brought forward. The boot is
placed on one part of the machine and a
stick of wood on another; motion being
given, one portion of the mechanicism
operates to prick the holes with an awl,
another to make the pegs, another to feed
the pegs to the mouth Of the holes, and
another to drive the pegs home. These
various operations are performed with
great rapidity, about two minutes only
being required to double peg each boot.
New MoroR.-Iti is proposed to en-
ploy the bi-sulphuret of carbon as a mo-
tive power. 1t is stated to boil at 1O8
degrees, and is capable of involving five
or six times the power of steam, and is
numbered with no practical difficulties
except an unpleasant odor, when allowed
to evaporate in air. Under the action of
this bi-sulphuret, any engine can be work
ed by steam at the same rate as before,
without interruption of its motion, thus
showing that the operation has been con-
Quoted without the loss of any heat pre-
viousIy stored in the water. The BIZ
sulphuret being decidedly more volatile
than water. much care is required to
treasure the heat to this extent, while
working with the new fluid. The calor-
ic or air engines of Sterling Ericsson,
Wilcox, Burnett and others, differed in
the principle of their motive power from
this invention-these simply drawing
from the discharging pipe aslarge guam
Of heat as possible, and transferring it to
The receiving pipe. The vapor of the BIZ
sulphuret of carbon has not yet been tes-
ed at any high grade of expansion.
CONSTITUENTS OF CHALK.-Dr. Mantell
states that miscroseopical analysis Of
'halk shows it ODE mere aggregation
Of shells and corals, so minute that up
ward of million are contained in a cubic
nch; the amorphous particles appear to
be the the detritur of similar structures.
These organisms, for the most part, are
caleareous shields and ehambered shells
Of the anin1alcules termed foraminipera,
which swarm in inconceivable numbers
