THE SOCIETY OP 4R78.

The eleventh annual exhibition of the models of
recently retested inventions has recently been opened to the
public at the rooms of the Society of Art,, John-street,
Adelphi. The collection is this year an unusually large
and interesting one, and shows at a glare the great im-
provements which have been abetted in our manufacturing
mechanism since the last salaries. The &racier tee-
newer, mining, and railway asechaalsor does not retain
=say =We, nor ry of particular 'Merest. There are,
however, some valuable improvements In insokteconsurning
turners for high premiere boilers, sad an istereeting
adaptation of corrugated iron plates for lon-
gitudinal reilway ropers. The machinery and ma-
nufacturing appliances clam is both more extensive and
interring than the previous one. The @meeker's/la rents
to have undergone many modal:area during the past year.
Among the models exhibited in this clam Is a rough sped-
nee of the native Irian challis, or cotton gin, which the
committee of the Cotton Supply Association had received
from the Bombay Chamber of Commerce, with a remart
that it might be submitted to the machinists of this retry,
with a view of obtaining for the natives a superior, end yet,
If possible, en equally cheap machine. The instrument is of
the coiner wood, put together In the roughest end most
humaly style ; and yet, strange enough, it is stated that no
machine so effectually separates the seeds of the cotton
from the fibre, with lees Injury to the latter.
The machine ors but es. In this ekes is a band
planing machine, the invention of )Guars. Muir and
Co., for the more accurate construction of the metal portion
of philosophical instruments. A breed-makingmachine
by E. Stevens, of Cambridge-reed, and a patent self-
regireeng weighing mathixe, exhibited by Nears. Burgas
and Key, are well worthy of notice, as are also 831E8 speci-
mens of bat steel, manufactured by the Bessemer perm
direct from pig iron. In the section of navel and military ap-
pliances there are an letter variety of improvements in
propellers and behinds, but cone of the models are of great
interest. In the military branch there are areal intassating
models of improved field and hospital tear, the
=veers of biejor Rbotles. There is or breech-
loadieg gun exhibited by Joseph Maudelay ; it is
• pretty model, but fir too complicated for actual 11111
vice. A. rather novel projectile, called • rocket gun, is ex-
hibited by Mc. Henry Reveley. in this piece of artillery
the projectile takes the shape of a ride ClllBl2Oll east with a
bore, the tork-hole being drilled se roll. Thia projectile
is lead ream • weraght-tron pin loosely fitting the bore,wblch
pin is itself held in a similar cast bore, but with clover fit.
lathe body of the genie a lump of cant-iron deny shape, the
larger the better. A line of eight is marked cc the body of
the gun, as well as sums the touch-hole, on every projectile.
The adventaees are stated to be rapidity of diserer, Wear
may projectile carries its own charge of powder, wad, and
touch-hole, and rands ready at hand to be slipped on to the
pin, requiring only to be rimed sad fired ; greet economy of
coca ruction, became no. turning or boring of cannon is ew-
quirod, as a very moderate fit will assure accuracy of aim.
The inventor states thee there I, pent iaerear of dynainio

The report of a one-mob rocket gun is stated te he p
Neal to that of a 6-ponder tired to thermal manner, and the
hem is such as to ensure its going head flee into tho target.
There be great destructive power, ea seceent of the enormous
sir of the projectile conspired with the bars. It may also be
provided with a second chamber in the rocket head, tarrying
a bursting charge, or liquid fire.
Copier Norton exhibits several specimens of his liquid
fire shells, both for cannon and ordinary ridge which
have lately been so succrolully tried at Chatham. Among
the philesop,hical appetites are exhibited Picketer
Hughes's well-known rimiest telegraph. Robinson end
Cr., of Greshartiouse, exhibit several torment the pre-
nivel grapnel galvanic 'batteries contrived by Mr. C. V.
Walker, P.R.S.,Whitehouse, whirr, allowed
to be the mar convenient and chars= of the kind yet =-
vented. The agricultural Implements clam shows the usual
variety of mowing Taschler, cue el which the =mad= of
Mr. Boyd, is emeringly insider ue el domestic
Lavender is very extenders, and coarse many =grim
and useful contrivances. Mennen. Hamilton end Nseh ex-
hibit a lock which Is absolutely unidelable. The bolt of. the
lock is not acted on by the key, but by • follower moved by
a handle so constructed that it deranges the lents at the
same time that it shoots the bolt, and thus the
lock is shot without the use of the key. The
bolt is et arranged that the key is acted upon more
then is necessary to char the levers ; thus the key can only
be =teethe:id into the lock when the bolt is fully shot, se a
bee to pass through a hole is the bolt, Witch coincides with
the key and the external keyhole—thus It is quite impossible
to shoot back the bolt whilst there issaything In the keyhole.
The exhibition is not deficient in Amman nohow.,"
among the most quaint of which le a band sweeping ma-
c.bice, which collects the dust as it is rolled over • floor or
carpet. Altogether thee:hillier Is an beterestiog one, and is
well worth the inspection of those intere.ted in mechanical
curiosities.

THE MAIL SERVICE.—SOUTILUIFTON, WIDNES-
DAY.—The steamship Orissa, Cassia Boy, left this day with
the weal Bombay mails, 996 boxes of spans of the value of
289,1061., end 44 passerigers, among whom were Captain.
Johnson, Lieutensat Smith, Paymaster Atkins, to. The
Tagus kitt to-day with the usual Peuleselar mail and 20

Bombay mail, is expected to The hiarmouis, from
Now York to Hantairp, with avian of the 16th, is hourly
expected. The New York, from New York to Diemen, with
the American mail and advice. of the Ifith, le expected

mails, is looked for on Saturdaynext.
THE bAEDINIAN AND FRENCH ALLIANCE.—We
understand that the French government are making en....
live purchater of coal In Liverpool for the purpose ot supply-
ing their vessels in the anticipated mmilict with Austria. A
steamer belonging toe Greek firm is mentioned se having
toen oharterd fur the transport of troops, but we believe eo
far, she has only berm engaged to carry code. At
we hear of no overtures having been mode to the
Company, nor the New York end Philadelphia Eliesmanitip
Company, nor is it likely that such overtures will be accepted
wstrl the Intended policy of Great Britain is the ceasing
strugale is asuonoced.
