What is called 'Freneh kid" gloves
are made from the skins Of rats. 1t is said
a company Of Frenehmen has been formed
in Chicago for the purpose Of curing their

In England there are sixty-tWo individ.
uaIs 10 every hundred scres Of land in
Irelsud, but tthirty-four; in British North
America, but one person to the square

A breech-loading rife can be loaded and
fred more than thirty times faster than
the muzzle-losder, and can be fred at least
hVe times more frequently with all the
movements made with the utmost deliber-
alton In the ordinary way OF firing on
the battlefield, it is estimated that whole
regiment is hit only once in two hundred
shots, and that with the breech-loadi ne
rifle ten times as many shots will prove
effective, thus increasing the offensive
! power Of the soldier fiftv-fold. Every SOL
dier, when ready for service, costs nearly
81, ,000 By the expenditure OF IS or $40
additional for each gun, one-half or one
third the number Of soldiers would be
equally efficient.
In 1862 there were 482, All tons Of sugar

At the Inauguration Of Governor Hahn
at New Orleans, on the 4th Of March, the
voices Of 5000 school children were &C.
compsnied by the strains Of several mill
tsry bands, and the chorus was sFelled
by the beating Of fifty anvils, the ringing
Of the bells in the city, and the thunder Of
| fifty pieces Of artillery. The cannon were
fired simultaneously by one electric wire,
] the ends Of which we're brought to the ts-
bic Of the conductor Of the band, and the
ringing Of the bells was controlled by con-
Meeting wire from the table with the tel
egrsph Of the fire department. The effect
was grand beyond description.
Lime made Of Italian marble is said to
be the most satisfactory for the calcium
light. 1t does not crack, gives good light,
and is easily prepared, by putting small
pieces Of white marble into q clear FIRE in
q stove or open CRATE. After remaining at
red heat for twenty or thirty minutes, it
is, after cooling cut into any desired shape.
Large guns are now loaded by steam.
Captain Eads ofSt. Louis has nearly ready
for service gunbost called the MilWsu-
kee, with two revolving turrets. Both
mount two l1-inoh Dahlgren guns. They
are loaded in the hold Of the vessel, raised,
and run out Of the ports, by steam, to be.
fred One man only, besides those who
load, is needed to work them. Mr.. Ste
vens, of HO6oken, exhibited similar ap-
psrstus two years ago.
The fumes of burning coffee are power
full disinfectants. Experiments have been
made in Paris to prove this A quantity
Of meat wss hung up in closed room un-
I'll decomposed, and then chafng dish
was introduced, and five hundred gram
mes Of coffee thrown on the fire. In few
minutes the room WAS entirely disinfected
In another room suiphurated hydrogen
and ammonia we're developed, and ninety
grammes Of coffee destroyed the smell in
half minute. Il is also said that coffee |
destroys the smell Of musk and sssfoetida. |
The best way to effect this fumigstion is
to pound the coffee in mortar, and then
to stew il on hot iron plate, which, how
ever, must not be red hot.
Nothing is more remarkable in Paris at
the present time than the number Of lit
erary lectures permitted by the govern
ment on almost every subject. This new
permission is strongly approved by those
Paris journals which notice the snbiect.
The religious and legislative journals ig-
more this new concession altogether.
The Congress Of Scientific Societies in

The first locomotive introduced into the
Island of Ceylon was landed last month
from the ship Pslmerston. It was placed

A complete TeleOsaurus, fossil reptile
hitherto known to geologists only by few
detached bones found in various qusrries,
has just been added to the museum Of
Srrssburg.
Gold. bearing ores, yielding from S22 to
SIP per ton, have been discovered in
Madison County, Missouri, and company
is to be formed to work them.
In the Latrobe Tunnel, in Virginia City,
Nevada Territory, mode of ventilation
said o,,hsve been in use among the ancient
Germans has been introduced. 1t is said
that when the tunnel was in only few
feet sn air shaft had to be sunk, and at
about the same distance further another
was put in. At this point the bottom of
the shaft WAS closed up, except a hole
about ten inches square, through which
passed wooden box fume of that size, by
which the air is conducted into the farther
extremity of the tunnel. The draft is 80
strong that no farther shaft has become
necessary, The tunnel now extends about
twenty-six hundred feet The Santa Fe
mine has adopted similar mode Of ven
tilation.
Professor J. Johnston, Of the Wesleyan
University, Middletown, Connecticut, has
discovered, contrary to all former obser-
Vstion, thrt sulphur, by friction with pa
per pyroxyline, or gun cotton, is excited
with positive electricity, as are also seal
ing wsT, amber, etc. This view is con-
frmed by experiments By Prof. B. Sill
