THE PROTOCOLS OF CONFERENCES—heId in
London relative to the affairs of Denmark—that i®,
the papers, so entitled, which were laid on the
tables of the Lords and Commons last evening'

respectively by Viscount Palmerston and Earl Rug'
sell—have come to hand immediately before ourgoing
to press. They extend to the number of 156 pages,
altogether. Thirteen Protocols in all, with four
Annexes. Thirteen, that is, counting as one of them
the preliminary Protocol of Conference held April
20th, 1864—signed G. Quaade, Bill,, Krieger, La
Tour d'Auvergne, Russell, Clarendon, Brunnowf
and Le Comte Wschtmeister. The signatures
of others of the plenipotentiaries drop in later
such as those of Apponyi, Biegeleben, Beust,
Bernstorff, and Balm]. The closing annex, with
which this batch of parliamentary papers is brought
to an end, consists of a very lucid, but for that precise
reason a very pitiable And humiliating summary of
the deliberations of the Conference of London,
from the 25th of Apri to the 22d of June, when

the said Conference collapsed.
At an extraordinary general meeting of share.
holders of the Indian Tramway Company, held
today, the report recommended that the proposi.
tion of the chairman be received, who had had per-
sonal consultations with the Governors of the several
Presidencies in India, for constructing the Base°
line of 20 miles to Bomb iy, an important feeder to
the Great Indian Peninsular Railway, and the
Hajeepore, Lalgunge, and Moz3fferpore line of 35
miles in Bengal, a tributary of the East Indian
Railway, both of which offer very greet advantages,
and will, no doubt, prove highly remunerative.
To enable the board to avail themselves of the
additional concessions above mentioned, and to
complete the two short lines in the Bengal
and Bombay Presidencies, it now becomes
necessary to issue the remaining 33,000 shares
which make up the sum of X 250,000. This addi-
tional capital will be received upon the same terms
as the previous capital, under which authority has
been given by special resolution, constituting one
of the regulations of the company, to pay interest
during construction at 5 per cent. until the lines
are opened for public traffic.

LOLD BROUGHAM'S NEW BILL ON BRIBERY.—
Lord Brougham's new bill for the more effectual prevention
of bribery has just been issued. It is to be made a mis-
demeanour, after the Ist of August, to commit bribery in
respect to the election of members of Parliament, and the
punishment to be one year's imprisonment, with or without
hard labour. A trial is not to take place at quarter or
general sessions.

SUDDEN DEATH OF MR WASHINGTON WILR'S.

—Yesterday evening at a public meeting, on the
subject of reform, was held at the St. Pancras Vestry Room,
when the borough members, Lord Fermoy, M.P., and lir
Harvey Lewis, M.P,, as well as several well-known speakers
and advocates of reform, were present. In the course of this
proceedings, after the first two resolutions had been carried,
Mr "Washington Wilks rose to second the third motion for
the appointment of a committee to carry forward the pro-
posals of the meeting. During his observations Mr Was,
to the consternation of those present, suddenly fell back in
a fit and was removed from the platform to a chamber near,
where several medical gentlemen attended him. In tho
meantime the business of the meeting went forward, an/
Lord Fermoy having concluded an address, Mr Harvey
Lewis was proceeding to speak, when the chairman an-
nounced that Mr Wilks, who had but just addressed the
meeting, was dead. The intelligence created an extraordi-
nary and painful excitement, and the meeting was at once
dissolved. Every effort to restore
i the unfortunate gentle-
man had failed, and he expired n about fifteen minuted
from the time ho was removed from the platform.
Twin—The shape of the bulb is of
importance.
Spherical bulbs are best adapted to
resist the varyingipressure of the atmosphere; while cylin-
drical bulbs expose larger surfaces of mercury, and are
therefore preferred for more delicate instruments. Various
plans have been suggested in order to obtain thermometers
of extreme sensitiveness for delicate experiments. Some
have been made with very small thin bulbs to contain it
Very small quantity of mercury; but in these the indicating
column is generally so fine, that it can only be read by tits
aid of a powerful lens. Instruments have been contrived
with spiral or coiled tubular bulbs ; but the thickness of
glass required to keep these in shape nullifies the effect
sought to be obtained—namely, instantaneous action.
Messrs. Negretti and Zambra, the well-known meteoro-
logical instrument makers, have recently succeeded IA
constructing a thermometer which combines sensitive.
ness and quickness of action, and which presents a good
visible column. The bulb of this thermometer is of a grid-
iron form. The reservoir is made of glass, so thin that it
cannot be blown ; it can only be formed by means of
spirit-lamp; yet its shape gives it such rigidity that ill'
indications are not affected by altering its position or
by standing it on its bulb. The reservoirs of the
most delicate of there instruments contain about
nine inches of excessively thin cylindrical glass,
the outer diameter of which is not more than the
twentieth. of an inch, and, owing to the large surface thus
presented to the air, the indications are positively instanta-
neous. This form of thermometer was constructed expressly
to meet the requirements of scientific balloon ascents, to
enable the observer to take thermometric readings at precise
elevations. It was contemplated to procure a metallic ther-
mometer; but on the production of this perfect instrument,
the idea was abandoned,—Minkris Journal,
