PARIS ACADE:

SITTINGS OF MAY 5 AND 10.

The Academy did not meet for the ordinary business
on the 3d, in consequence of the annual meeting of the
united academies having been fixed for that day. The
sitting was therefore postponed to the sth. On the 10th,
the academy met in the usual way. We subjoin a re•
port of the most interesting proceedings of the two sit-
tings : _ _

account given by the notorious Johnstone, the smuggler,
of the submarine boat in which he proposed to remove
the Emperor Napoleon from his captivity at St. Helena.
There has not, we believe, been much improvement upon
Johnstone's system of operation and the submarine ap-
paratus of Croisic appears to have been on a nearly
similar plan. The real improvement in submarine navi-
gation is the discovery announced about two years ago,
which restores to vitiated air its vital properties, remain
under water several hours without receiving a fresh sup-

M. Arago gave an account of some improvements
made by M. Delvigne on the apparatus employed by
Captain Manby for saving shipwrecked persons, by
conveying to them a cable fired from a gun or mortar.
The improvement consists in a greater degree of cer-
tainty as to the arrival of the cable, and the impossibi-
lity of inflicting any injury on the persons for whose re-
lief it is meant. M Delvigne in his experiments has
been able to cover a range of 385 metres, but he hopes
with a Paixhans gun to obtain a range of at least 100
metres more.
A report was made of a break for railway carriages,
invented by M. Laignel, and almost generally adopted
in Belgium, where it is said to have rendered im-
portant service, but which, in spite of all exertions
of the inventor, has been tried by only one rail-
road company in France. The committee of the
academy charged to examine the system, and report
upon it express great approbation, and as a proof
unanimously recommend that a prize of 2,500 f. shall
be awarded to M. Laignel. W e hope this report
will have the effect of inducing some of our railroad
companies to make a fair trial of the .break; but we are
still of opinion, until a permanent commission shall be
established, with funds to pay for experiments, and
power to compel the .ase of improvements when their
utility shall have been proved, nothing, in the interest
of the public will be done. The immense number of vain
things submitted to the companies is made an excuse for
confounding good with bad, and the frequent sacrifice of
human life seems to have little effect towards the adop-
tion of plans which, in the opinion of practical men,
would diminish the danger that attends the existing
modes. _ _ _

fining it to seasons, as is now done. M. Barrol sent in
a paper showing the comparative advantages and disad
vantages of the two modes of gilding—viz., the old
process by mercury, and the electro-chemical. For
solidity he gives the preference to the former, but for
safety, where the article gilded is one for domestic use,
and comes into contact with acid, he prefers the latter.
