Sta,—The working class of London are in a most unjust
predicament; without any facility offered for their rascal-
blings they have no means of taking part in public agita-
tion within the metropolis without resorting to open air
meetings on Kennington-common, Satithfield, Cfcrkcia-
, well-green, and other localities, all of which are more or
less removed from a central situation ; open air meetings
terrify the weak and scathe the prejudiced ; and as it is
rarely possible to get a magistrate to preside on such oe..
casions, they are looked upon as assemblies of eviladis: osed
perms, who will rob, burn, or steal to carry out their ob-
ject; rather than the organization of rational, honest, and
independent men, who, living by toil, and !reducing the
wealth of the country, have s right to say what they desire,
and to demand what is just.
It is true there are here and there large buildings
in different parts of London, open for public meetings,
but all by some cause, pecuniary and sectalian, i-ra shut
(against the " unwashed" multitude. Exeter Hail accom-
modates 4,000 persons ; but ere its stately threshold eau
be crossed, report says 40 guineas mug be given, end then
beware of the apron, or the dusty jacket, for these relics nf la-
bour would contaminate the place where the sons ar,d daugh-
ters of ease listen to the dulcet strains, or sit through writ y
hours at the shrine of pious eloquence. The same applies
in a great extent to the Cro%,n and Anchor and the Lon-
don Tavern, where their 14 or 20 guineas meetings of ab ,ut
2,000 persons keep them select and at the
serrice ~f rte:cly
a class, be it: ol.jeet poli:ics, religion, or commerce.
As to the motives or necessity which in every erase diccer
tates these amounts of rental for the means of hul ling
public meetings, it is unnecessary to discuss; as an indi-
vidual opinion, yet one that is shared in very largely by
the thinking portion of London operatives, I look at the
several charges as being most exorbitant and unjust; and
it is no extenuation of the matter to know, that because, no
other less figure can be obtained in a neighbourhood, that
one based on extortion must necessarily be submitted to.
. _

It is now uugenteel to hold meetings in the evening, a
part of the day held sacred by the gentry to worship at the
epicurean shrine. If to meet in public be good if to de-
clare openly and honestly the sentiments of collected thou-
sands be necessary to the public peace and happiness, is
the name of common sense and liberty the means ought to
exist in London for the most perfect freedom of speech
and assembly. But the sons of labour are w•ithbut a
home, how can they meet? Let them build a Trades'
Hall in the centre of London, and throw its doors open to
all parties without stopping to inquire their politics or
religion.

Working men—the Trades' Hall council offer them-
selves as pioneers in this good work of facilitating the
building of a Hall of your own, in which a library, rend-
ing• room, and lectures are designed to be provided ; the
help of the trades and operatives is only required to mature
this desirable project ; what is 15,000/. amongst so large
a body of men, when divided into shares of I/. each, on
which 2s. per share is at present only required ?
All who love their country rightly—all Who sympathise
with the stole neglect of the working class by others, and
desire to see it come forth in power, intellect, and tern..
perance, will rally at once to support a scheme that is prac.
ticable, interesting, philanthropic.
I am, Sir, your obedient servant,

POISONING. - NEW EXPERI-
MENTS MADE BY THE CHEMIST ORFILA.

The itioniteur contains the following account of some
new experiments made by M. Orfila :
_ _

M. Orfila commenced his experiments to-day in one
of the ampitheatres of the Faculty of Medicine, before
a special Commission of the Academy of Medicine and
a numerous audience. The Professor made a number
of experiments on poisoning by arsenical acid and tartar
emetic, and, by the programme which he distributed,
undertook to prove—

1. That arsenical acid and tartar emetic introduced
into the alimentary canal, or placed on the sub-cuta-
neous cellular tissue, are absorbed, mingled with the
blood, and carried through all the organs of the animal
economy.
2. That they remain for a certain time in the vis-
cera and muscles, where their presence is demonstrated ;
but that, from the time of the poisoning, a part of the
portion which is absorbed leaves these tissues, and is
eliminated by the urinal process.
3. That this elimination, which is much more rapid
in case of tartar emetic than of arsenical acid, continues
during several days, until the tissues in question have beets
completely freed from the presence of these poisons.
4. That it is therefore advantageous, and even indis-
pensable, in the treatment of poisoning by poisonous
substances, to favour the secretion of urine.
5. That it is possible in most cases to distinguish
whether the arsenical acid and tartar emetic which are
withdrawn from the viscera of the human corpse have
been absorbed during life, or have entered those viscera
through " cadaveric inhibition" after death.
6. That the most fitting process for detecting small
quantities of those absorbed poisons, consists in di -
stroying the major part or the entire of the organic
matter, by carbonising them with concentrated azotic
acid, or decomposing them with ezotate of potash, and
introducing the products into 111arsh's apparatus modified.
7. That it is always easy to distinguish arsenic from
antimony through the form of spots, and to be quite
certain that these spots proceed neither from the appa-
ratus nor the chemical agents employed.
8. That there exists in the bones, both of man and
of several animals, an arsenical compound insoluble in
water.

O. That from the muscular flesh of the human body
may be extracted a matter which M. Orfila believes to
be formed of an excessively small proportion of arsenic,
sulphur, And an organic substance.
JO. That in the earth of certain cemeteries there are
found quantities, infinitely small, of arsenic, which boiling
water will not dissolve.

11. Finally, that it is easy, in a legal inquiry, to avoid
those errors which would appear at first sight to spring•
from the admitted fact of the presence of arsenic in
human bones and muscles, and in the earth of certain
cemeteries.

M. Orfila then proceeded to make his experiments.
Several dogs were poisoned ; some by the introduction
of 12 grains of arsenic in tartar emetic into the sto-
mach, others by inoculating them under the skin wig h tra
infieitely small quantity of these poisons, imbibing it
through the vessels being found a much more ready
mode than absorbing it through the digestive organs.
Upoa the death of these animals, which was expected
to take place in 24 bows, ulterior experiments would
take place, After having explained the theory of
Marsh's apparatus, and satisfied himself and his atidi-
ence as to the purity of the reaction which he meant to
emr boy, M. Orfila proceeded with his comparative
proofs upon the remains of two dogs, one of which had
not taken arsenic, and the other had died at the expira-
tion of three hours after receiving a quantity of arsenic
into his stomach, preliminary precautions having been
taken against vomiting, and against the action of the
urinal process. The following results were obtained :---
1. The urines of the dog, which bad been poisoned,
yielded, when submitted to Marsh's apparatus, m..knifest
signs of arsenic, while those of the dog which had been
killed by suspension, without poison being administered,
did not exhibit one atom of it.
2. A very small portion of the liver of the poisoned
animal, subjected to a preliminary treatment by suitable
chemical processes, and afterwards exposed to Marah's
apparatus, yielded multiplied spots of arsenic, whilst
the entire liver, lungs, spleen, and heart of the dog
killed by suspension, on being submitted to the same
chemical treatment and reactions, did not exhibit the
smallest trace of arsenic.

the sale of the stock. Having previously got his wife and
servants oat of the way, except one female and a
little boy, on Friday night, between six and amen
o'clock, two men came into the shop, when Ruffles
appeared to be very disconcerted, and exclaimed in the
hearing of the servants, " the Bailiffs are come at last—.
You must immediately go to London with a letter to my
solicitor 1" and gave her a piece of paper which she sup-
posed to be a letter, instructing her to remain for an an-
swer. Having thus got all obstruction out of the way,
except the little boy, who was afraid to say any thing, a
van was brought up to the door, which had been some
time waiting in the neighbourhood, and the whole of the
stock of the shop placed therein, ;and the whole party
drove off. The little boy knew there was somethirug
wrong going on, although he was afraid to speak ; and
after Ruffles and Co. had left, he proceeded to Green-,
with to inform Nr. Smith of what had taken place, and
he lost no time in making the best of his way to Well-
