BRITISH ASSOCIATION FOR THE ADVANCE-

KENT OF SCIENCE.

Yesterday (Monday)
_the meetings of the sections
were renamed at Ipswielt, but many of the important
members who were mment ea Friday have taken their de-
putise, end the attendemeamlly we thin.

The action of the copying electric telegraph was explained
by Mr. Bakewell, who illustrated the explanation with ex-
perimental transmissions of written messages.
The pendulum experiment of M. Foucault has been se-
veral tunes referred to in the physical ea well ea in the me-
chanical section, and different modes have been suggested by
which the rotation of the earth may be rendered visible, by
the suppression of bodies not in • state of vibration. These
esperimenta, however, are attended with more difficulty
than the vibration of the pendulum, respecting which no
correct popular account has been given to explain clearly
why the apparent rotation of the earth, as shown by the
pendulum, varies in different latitudes from the diur-
nal revolution. It is sufficiently clear that at the poles,
where the point of suspension would be fixed, the ap-
=tation would correspond with the real, if the pen-
rotation
continued to vibrate in the same plane ; it is also
deer that, at the equator, where the point of suspension
would move as rapidly as ihe earth, no indication of rota-
tion would be visible but the intermediate effects at lati-
tudes appeoaching thei poles arc difficult to calculate, and to
reader tatellgible in • popular manner. The simplest
111181.11111 of seeing the rotation of the earth is to look at one of
the Iliad stars through a good telescope, when the visible
imoveseent of the star from the field of vision indicates per-
eeptibly the progress of the earth from west to east.
Messrs. Bond, from the United States, exhibited, in the
physical r ction, some beautiful daguerreotypes of the moon,
taken at Cambridge, U. S., with& telescope of twenty-three
feet focus. In these pictures of the moon taken with her
own light, the size of the disc, if at full, would have been
shoat three inches, and the mountains and volcanoes were
very distinctly pourtrayed.
In the chemical section, Dr. Daubeny read a paper which
occupied two hours, on the chemical nomenclature of orga-
nic substances. Dr. Whewell recommended that a com-
Lae, should be appointed, with a view to take into consi-
deration Dr. Daubeny's proposed system, and to recommend
en
improved nomenclature tor the adoption of chemists to
meet the wants of the present advanced state of the science.
In the mechanical section • wordy war was carried on
between the advocates of Mr. Am Whitney's project of a
railway from lake Michigan, across the Rocky Mountains,
to the Pacific, and Mr. Alexander Doubt's plan of a railway
communication between the Atlantic and the Pacific,
through the British territories.
The adjourned meeting of the general committee was
held last afternoon, when it was decided that the next
meeting of the association shall be held at Belfast.

PATENT LAW AMENDMENT.—A third bill of the
present session, to amend the patent laws, has just been
printed, by order of the House of Lords. It was brought
forward by Lord Granville, who introduced one of the other
bills, and Lord Brougham the other, making the third mea-
sere in the Lords. The present bill contains 22 clauses and
• schedule of forms. It is proposed to appoint commis-
sioners, who may appoint examiners end °dicers ; may
make rules, and arc to report annually to parlisment. By
ISO of the clauses in this bill, the use of inventions abroad
are to have the like effect on letters patent as to the use or
publication in the United Kingdom.
TILE SELF-ACCUSED MURDERER AT MANCIIESTER.
—The youth from Dublin, named En gene Keenan, who
gore himself up to the county police at Manchester as the
murderer of a fellow-clerk in the Government Valuation
Oder at Dublin, by mixing oxalic acid in his porter, turns
out to be insane. His father came over from Dublin to ap-
ply for him on Saturday, alleging that he had exhibits&
symptoms of madness for upwards of three months past. It
appean that, in consequence of his statement, the body of
his late fellow-clerk, Conellan, had been exhumed, but ise
trace of poison was discovered. The immediate muse of
death had been rupture of the aorta. Keenan had pees
viously surrendered to the borough police on • chary of
highway robbery, which he accused himself of, near ths
town, but they discharged him after making inquiries, rot

TREATMENT OF IMMIGRANTS AT NEW YORII.
A movement in reference to the Commissioners of Emi-
r train was made in the Assembly yesterday, which we
Lope will be followed up. If the legislature wish to pro-
'mote the cause of humanity and philanthropy, they wM
albite • searching investigation into the manner in which
Ithe unfortunate emigrants, who arrive at this poet from all
parts of the world, are treated. We think it can be proved
with great ease that the Commissioners of Emigration are
mere of a nuisance than anything else, and that more rob-
bevy and ill treatment have been practised on emigrants
dace the appointment of the commissioners, than was the
I ease previously. The city of New York, the state of New
York, the whole country, is disgraced and degraded before
" the whole world, and before heaven, for tolerating the hal-
, emities that are practised on emigrants arriving in this city.
• We call upon the legislature, therefore, for the sake of hii-
amity, to follow up this movement, so that the system of
eldhusy may be put an end to. If we allow it to continue,
we shall merit the fate of Sodom or that of Gomorrah. Ten
hundred times ten hundred proofs can easily be obtained to
substantiate the truth of what we have repeatedly said con-
cerning these impositions. Let the diabolical confederacy
of runners, rowdies pugilists, and emigrant boarding-
' horse-keepers, be broken up, and the empire city of the
empire state relieved of the stigma which now rests upon it,
kr tolerating so long the villanies practised on emigrants.—
