The centrifugal pump, Gan American inventory
is taking the place of all others for heavy pump
ing, in England.
The Codfsheries of the North Pacific are at
tracing attentionin Pacific States, and promise
to become important
The curious fact has been observed by means
Of the microscope, that perforations made by the
electric spark are uniformly pentagonal in form.
The brilliant prismatic colors of the pearl are
attributed to the decomposition and reflection of
the light by the numerous minute grooves on its
surface. s. 7~-- q - -
"A jet of yapor of ether is now thrown upon
parts subjected to surgical operations by an nstru
ment made for the purpose, producing insensibilty
of the part in from two to four seconds. The pa
tient becomes spectator: 'merely this and moth
ing more" f -. .r
The Canadian city of Coburg is brilliantly
lighted with gas from pine stumps, bones, and 9TH
er vegetable and animal refuse, at a reduction of
one dollar per 1000 feet from former prices The
works are also much cheaper than those required
for coal gas.
The sale of horsefesh is increasing in Paris.
There are now seven butcheries in that line, dis
posing of about 10000 pounds per week, at from
five to nine cents per pound. We presume that
Americans who visit Paris next year will be largely
fed horse steaks, horse hash and horse sausages
The market value of skilled and educated labor
in glass and iron, is enormous. In the window
glass factories of Pittsburgh, for example, blowers
and fatteners receive $3.50 per month"; and the more
skiful make as much as $40 per day, and that for
long periods. Some of the meters in the steel
works clear from $40 to $22 per day.
1t is calculated that If the earth was a cannon
ball, shot at the from its present distance with
the velocity it now travels with, and the moment
of explosion telegraphed to the sun, they would
get the telegram there in about five minutes, and
see the earth coming in eight minutes, and would
have nearly two months to prepare for the blow,
which they would receive about fifteen years before
they heard the original explosion. %.
DR. Burggrave, of Client, has recently published
a method of dressing wounds with sheet lead.
After carefully washing the wound, the lacerated
parts are drawn together and held in position by
very thin strips of the metal, attached by sticking
plaster This permits a jet of warm water to be
thrown under the armor from time to time, to
cleanse the wound and refresh the parts. In cases
of injury by machinery and gunshot, such dressing
may often save a limb or even life.
An Ingenious French anthmetician has calcu-
lated that the space which young Partisan belle,
who is fond of the exercise of dancing, traverses
in the gay saloons of Paris amounts in the course
of one dancing season, to four hundred and thirty
four miles and half. He has also estimated that
French lady, fond of performing the functions OF
a teetotum would spin round in waltz in one
night as many times the wheels of steamboat
revolve while running the distance between Dover
and Calais ~ II ~
A correspondent OF New York Journal calls
public attention to the dangers of using gasoline as
an Illuminating fluid. He says this substance gets
its name from its extreme volatility and produced
in the dislaton of petroleum, having until lately,
however, been regarded as vast product. 1t is
one of the lightest and most volatile liquids known
its specific gravity being less than that of ether and
it is so volatile that ounce more uncovered
in wine glass viii entirely disappear in afew hours.
1t is highly infiammable, burning even on the sur
face of water and as it is almost uncomfortable
and dangerous as gunpowder, the Pubic are
Justly warned against using 1t for Illuminating
purposes.
Repeated efforts have been made of late years
to adopt wood for use in the soes of shoes, but as
vet without iattering success. One manufacturer
succeeded, lust before the war, in starting con-
siderable Southern trade in woodensoled shoes for
the negroes: but the manufacture has not been re-
sumed. In this instance sole Of maple was fat
ened to the upper with screws. A patent was OBJ
tanned. few years since, for a compre ssed wooden
sole. This has been abandoned. A company in
New York have lately been manufacturing shoe
with soles and heels of maple, and the shank of
leather; securing the upper to the sole by a thin
rim of iron clasping the edge of the latter. A Ie-
cent Boston invention fastens shaped maple sole
to the upper by means of staples. Ii is In use
