REVIEWS OV THR WORK.

"The author of this singular and talented work is a legally quali-
fied medical man, who has evidently had considerable experience in
the treatment of the various disorders arising from the tellies and
frailties of early indiscretion. The engravings are an invaluable ad-
dition, by demonstrating the consequences of excesses, which must
act as a salutary warning to youth and maturity, and by its perusal
many questions may be satisfactorily replied to, that admit of no ap-
peal, even to the most confidential friend."—Era.

ELECTRIC TELEGRAM—At the sitting of the Aca-
demy of Sciences in Paris, on the 4th instant, two letters were re-
ceived on the subject of electrical telegraphs—one from Mr. Morse.
of the United States, the other from M. Brcguet. Mr. Morse, who.
as well as Mr. Bath, has now before the Academy his plan of tele-
graphs, which he considers to be superior to that hitherto adopted
in France, writes that, in consequence of the success of the experi-
ments made with his system, he has been charged by tae Govern-
ment of the United States with the construction of several lines of
telegraph, covering a total extent of 300 leagues. lie adds, that
the apparatus for signals, which he presented to the Academy of
S Aences during his stay in Paris, is found to answer admiorablyt'.,
and performs sixty signs per minute. The chief object f
Breguet's letter is to remove all doubt m to the power of the
electric fluid when its transmission to a great distance is required.
M. Breguet informs us that, by a combination of his
thr app leear4us,
eshe,
has transmitted the fluid over a distance of thirty-t
he found the
without increasing the power of his battery', and tha
circulation as complete as for a shorter distance. Another point in
M. Breguet's communication relates to the question as substi-
tution of iron for copper wire. The use of iron wire had been recom-
mended by way of economy, but an objection had been raised on the
as copper, and that
supposition that iron was not so g
the economy in the first cost woulodobclea conductorore than counterbalanced by
wmerful battery than is required
the permanent expense of a more
for copper wire. M. Breguet's experiments prove, that iron may be
used with as much certainty as copper. 'These communications are
as the commission appointed ,by the
important at this moment,
French Government to report on the different systems of electrical
telegraphs which Aar 0 been submitted tO it,cannot be much longer
delare4.
