SCIENTIFIC INTELLIGENCE.

A NEW SUN!
A very interesting experiment has lately been con-
ducted in the Armoury of the Tower of London, in
which the most intense light ever yet produced by art
was exhibited. It was excited by directing a jet of
burning alcohol, or the flame of a spirit lamp, upon a
piece of lime, by the action of a stream of oxygen gas.
The light thus produced is calculated as being eighty
times more intense than an equal area of light emitted
by the combustion of an argand lamp. It is said to be
visible at a distance of 120 miles. No satisfactory
theory, in explanation of the phenomenon, has been
hitherto discovered, but it appears that other earths
will also exhibit the same brilliancy when heated by
the means above described. The peculiar earth termed
Zireon is found to be pre-eminent in this property.
Its value, for the purposes of a signal, will readily
suggest itself to our Readers.
Another new Steam Engine has been projected, in
which spirits of wine or tether is substituted for water.
The necessity of a boiler is superseded, the liquid
being contained in the cylinder, and raised into vapour
by the heat of an argand lamp.

We are much gratified to learn that the Royal Col-
lege of Physicians are about to open their splendid
Edifice in Pall Mall East, with an interesting series of
Lectures, the subjects of which are certainly highly ap-
propriate to the occasion. The erection of the new
College must be considered an epoch not only in the
history of that learned body, but in that of the profes-
sion of physic ; and it is therefore proper that its pro-
fessors should take a review of all the late discoveries
and inventions in their art, in order that they may,
with some certainty, direct their future investigations.
The following is a Syllabus of the Lectures which are
to be delivered by one of their Fellows, who has been
selected for the purpose :

LONDON BRICK COMPANY.

On Tuesday a Meeting of the Directors and Share=
holders of the above Company, took place at their
Office, Lancaster-place ;
Capt. BRENTON, R. N. in the Chair.

--•••••
After some remarks by the Chairman, on observa-
tions in a Morning Paper about the Company,
Mr. Winn read a report, and stated that there were demands
upon the Company to the amount of 14,050/. and that they had
bricks which would produce 7,000/. and that the call now due,
with another call for the same amount, would meet this demand,
and that in July there would be manufactured a sufficient quan-
tity of bricks as would yield a profit to the Company of Fifteen
per Cent.

A Shareholder inquired whether two calls would he sufficient.
CHAIRMAN.-Yes.

Shareholder.—Are there any debts due to the Company?
CHAIRMAN.---Abollt 4001. which are perfectly good.
Colonel CARMAC said, the Company was not got up for Stock-
jobbing purposes; it was a bona fide investment, and the Direc-
tors held 472 shares ; they were under acceptances on account of
the Company, and he trusted that the Shareholders would come
forward and pay the calls. He concluded by moving, that the
time for paying the call should be extended to the Bth of June.
Sir FKL!x AGAR seconded the Resolution.

The CHAIRMAN said, that one more call besides the present
would be quite sufficient, and proposed a Resolution, pledging the
Directors not to require more.
Mr. Wana opposad the Resolution.
Colonel CARMAC approved of the Resolution proposed, as cal-
culated to inspire confidence.
It was agreed that the Resolution should pass.
Mr. Wmin—ln the event of the calls not being paid, what is to
done?

A Shareholder—lf the calls are not paid, the Company must stop.
The CHAIRMAN then read a letter from Mr. Harris, en Attor.
ney, who solicited that his Share should not be forfeited, end
alluded to his transactions with the Company, and requested that
the money due to him would he allowed in lieu of the calls.
Colonel CAastAc—The Resolution we have just passed enables
Mr. Harris to become again a Proprietor.
Mr. %ea said, Mr. Harris's claim to be admitted was the
fees and emoluments due to him for his attendance as a Director.
Colonel CA RMAC—Stop, stop I
Sir F. .AGAR-- That is private.
A DinecTort— TAat is irrelevant.
The SEcuemaY then moved that Mr. Harris's letter should be
taken into future consideration.

w. •• •••
The CIIAIRMAN said, that he would feel much obliged to the
Reporter, if he would omit the subject of Mr. Harris's letter in
his report.
The REPORTER replied in the negative, from which moment a
feeling of regret was evinced at his being admitted, and a desire
to conclude the business of the day was very visibly betrayed by
the countenances of the Directors.

Colonel FAIRMAN moved a vote of thanks to the Directors anti
Chairman, and the Meeting broke up.
