SCIENTIFIC DI SCOVER Y.

.The Count de la BoNTA've, in a Memoir to the
French • Institute_ says, " he has discovered the
means of dyeing unalterable colours, the compo-
sition of which is perfect, viz. blue upon wool and
green,: fellow, violet, and 9 other colours ; to
wit, a yellow upon .wool, as strong and more bril,
liaut than. the former : two greens, one of which
will resist the action of fire itself ; two fine blacks,
one without copperas,'which can neitherhurn nor
harden silk, ny more than wool; and another,
which resists sulphuric acid potash in a state of
ebullition, as %vell as the action of the silo and
air ; an unalterable puce colour ; a crimson on silk,
much cheaper and -more durable than cochineal ;
and 'lastly, a pure pink, completely unalterable
throu'gh all the shades of flesh colour.
" Add to these twelve new colonrs," says lie,
which MO be obtained pure in all their shades,
a very be-aitOrnl white, never liable to torn yellow,
which. I have saceecaed in. giving to wool A well
as silk, anti, which spreads much more than their
natural white.-7-if we only add to this, the fastest
colour of the ancient dye, or the fine red yielded
fry alkermes, to fill the palette; and the problem
will be solved.
" Of these twelve unchangeable col Ours, eitiht
have been suhjected.to the action of the sun under
glass, during the four latter months-of last wit,
suer (1813), without undergoing the least altera-
tion.
.Fire has no effect upon the ninth colour,
and the three last.are the fi nits of My' industry
through the preceding winter.,"

IMPROVEMENT OF GRAY?S.---A respectable Cor-
respondent in Hillshorongli, communicates the
following sugge9-tion fdr the improvement of
Grates : •

" As any plan, however simple, that can at all
tend to the saving of fuel, may be useful, I beg to
oi,serve that the present construction of Grates
may be considesrably improved by having the bc,t,
torn entire of thin iron, as, also the 'two lower
bars within a quarter of an inch of it, and next
each other. , The Grates in use should 'have
another bottom. of thin iron, with a bar rivetted.
'OH staunchions, so as to limit the space as above
described : this too will have its advantage, as it
will draw out to remove the ashes. • At first this
may appear of trifling importance ; but I know
from long experience, that where turf is -the
chief fuel, one-half is saved, and nearly one7third
of coal. This could be more :fully explained, to:-
gether with its effect on the draught of chiwnics ;
but presume merely inserting it will suffice."
CAUTION TO FAMILIES.-Sunday last Mr„„an,d
Mrs. Sheicay, of Bethnal Green, sent out in their
garden for a stick of horse raddish, and the ser-
vant brought in a root, called
." Pope's Roof,'
which exactly resembles, horse-raddish, and un-
fortunately was used instead. of it. The conse-
epienee was, that they both found themselves very
ill that evening, and the next morning, on- send-
ing for a Medical. Gentleman,. he d.eciared them,
both to he dangerously poisoned. They remain

Hart, the robber; who was killed in a conflict
at. Mr. PartTO'N's mill, Was interred on Monday

could not inthice him to commit such atrocity, as
notes to the amount of Si. besides a watch were
found on his person ! he had also 10 sheep on a
common hard by; was on tire eve of being married,
and had a new snit of clothes sent house for that
purpose. Having lodged with at man of the name of
Dennis, it was thought proper to search. his premises

_quantity of corn was discovered in a
stubble stack, and several sheep-skins in a dung-hill.

Page, the accomplice. with liort, for, whose ap-
prehension a reward of 20gs. alas been offered,
was seen at Wrotham, on Sunday seennight, iii
company with a man of the name of Brake:field,
whose residence is at Biddenden. From the wound-

A truly disgraceful scene occurred in this town
on Tuesday last : A man came from Gouldhurst
for the express purpose of selling his wife, sup-
posing that the Cattle Market was held on that
day ; but finding his mistake, and being deter-
Mined to get rid of his rib, he adjourned with
her to the Coal Barge public-house, where,
after many biddings and. -high commendations on
the charms and. virtues-she possessed, was sold
for the sum of One Guinea and a Pint of Gin, to a
countryman, who came front Goodhurst for the
purpose of buying her. We hear she has five
children, one of which she 11;14 in her arms when
TRALEE, DEC. 29.—A man of the name of
Manganc, of Glip, was barbarously murder-
ed on Tuesday week last, at Bllylogeord, in
this county ; Godfrey Leonard, 'Esq. of Rushy
Park, a Magistrateof the county (no Coroner being
convenient), held an inquest on the body; and .4
verdict was returned by the Jury of Hilful Murder
ntzahist .Michael Mulvihill, James Moore, and
Wm. Dinahan, one of whom has been appre-
hended, and sent off for the jail of this town; we
understand some circumstance of a rely
ex..raor.
dinary nature occurred in the perpetration cif this
barbarous deed, with which we are unacquainted;
(Kerry Evening Post.)

following singular and unfortunate
cum Stance happened on Tuesday week. A sailor,
about 8 months since, brought home a spiked
hand-grenade, and gave it to his mother, vhd lives
in a cottage at Sprouston. Being unconscious of
the combustible materials with which it was filled,
no care was taken to keep it from fire; and it
accordingly been used for some time back, for
.P',,eaking coals and other purpoies. Unfortunate-
;7, however, on Tuesday, it was put upon the side
of the are in order to-support one ends of a piece
wc,titl, which had been laid on to burn, when
tt..ic grenade having become heated, exploded, and
shattered the woman's jaw, and otherwise injured
her in so dreadful a manner, that she, continued

for some time in a state of the most. imminent

danger. She is now, however, in a fair way of
recovery. Another woman was also tench hurt,
and the cottage neatly set on fire ; hut by the
timely assistance of the neighbours, who 'were
brought to the spot by the noise of the explosion,
the flames were quickly extinguished.---(Kelso
