Tx t mucilaginous substance of ti .e
nnti-scripros, or common bluebell o-r bare hell, lta:
been successfully used by calico printers,- instead of.
gum arahie; the mode in use, is to cot the bulbs,
arid v.dien clr:;.ed, to retity2e thm to powder, which
they yield in the'proportion of about one-fourth of
their original weight, and this powder is used ii
fixing the e,lours in the same maneer as the gum,
and in like quantity, viz. r oz. to 4 nz. of mei:.
dant. These ,1-(wts are abundant in ail parts of the
country, and might he cultivated in y required
quantity, at an expense itifipiteiy short of the pre.,
sent cwt of gum.

The follo;ing very simple prcee3s will produce

blackened an earthen plate or dish, by holding it
over the flame of a candle, rnix up, with a camel-

common carpenters' glue may be used instead a

Some • recent experiments, by a Fren.ch chemist,
have estah7i,hed the possibility of rest iaticid.
essential of an oil as thick as turpentines.'
and which had. no stud( by,which the plant Iron:"
which it was extrane3 could be d'istingu'ished, were
mixed with two draelam. s cif sulphuric ether, aii4
distilled in pure water frit tout days, when two
ounces and a half of oil passed over as clear and ai4
fluid as. spirits of wine, and having the best and
most.decided ockur of wild thyme—there remained
in the still two ounces of a resinous matter of a dark
red colour. ..In this, and• similar experiments on
Other rancid oils, the ether obviously developed the
smell of the oil on which it re-aCied, or rather it
recomposed the, oil by transmitting its hegrogenous
principle to the oily base. •
An artificial alum is prepared by adding five parts
of murizte of soda to too parts of clay, made into
balls by means of water, and calcined in a reve the,
rarory furnace—to the powder a 4th part of it#
weight of sulphuric acid is added it intervals, anti-
afterwards eight or ten times as much water ; the
alum is separated from•the liquid by., a solution (.;E
potash. To manufa&• ers of Pr ussian' blue, or tilt-
tillers of aqua-fortis, this system.of fabricating alum 1,
would, be particularly advantageous. Jr. France,
M. Curauda'and others have made this salt artifi-
cially with a profit of zs per cent. over the alum
of commerce.

We have already mentioned a fulminating powder
compounded of oxigenated muriate and arsenic,
which explodts with the rapidity of lightning, and
in comparison with the strongest gun_powder, make,
the iatter seem to burn with e.trreine slowness. Its
clear are so violent and so dangerous, that no sttc.•
cessful experiment hai yet been made to apply it to
objects of use; but it is believed to be capable of.
extensive and important applications.
A Frenchman, .named Descotils, has discovered
a new metal in, the ore of platini ; it is presumert
that palladium may bean alloy to it with mercury;*
Another FrenChman, named Thenard, has-disco iered
a blue, .as fine and beautiful as the lapis lazuli,:ot
ultramarine.

It is now contended thar.palladium is a new nob??
metal, and not, as was asserted, a compound of pia-
tina and quicksilver; awl the person who found is
or made it, fur the point still undetermined, has,
deposited 201. as a premium to any one who. wiil
make twenty grains of it.
