scrENCE.ANn INDUSTRY.


The fist attempt to manufacture
best sugar IN Melbourne, Australia, has
proved Improbable.
At Limoges a gunsmith has invented
a breech self-loading carbine which dis
charges twenty bullets q minute. It
has been submitted 10 the French milf
tary authorities.
Nashville, Tenn, recently cele-
brated the success attained by the to-
bacco industry there, the quantity of
tobacco received having increased fIom
geo hogsheads three years ago to lice
last year.
The exchange for the sale of manu-
factued tobacco in Richmond, Va, is
found TO facilitate business and encour-
age merchants to buy there who former
" purchased tobacco IN the larger cities.
During the first four months of this
year ASP ships, with an aggregate ton
age of 824, 069 tons passed through the
Suez canal. In the same period last
year the number of ships was 1853,
measuring 729, 906 tons.
A new hot-blast oven is in use in
iron-making at Troy. It utilizes as fuel
the gas generated in the furnace, and
being placed on the ground, the blast
from 1t passes into the cupola with little
or no loss of power.
1t is intended in Paris to construct
street railroads on nine distinct routes,
making in all about thirty-two miles of
line. The company which has the mat
ter in hand has capital of 81 ,O00, 900,
and lately invited subscriptions to a
bonded loan of 81, 900, 900.
Although the new alizarine-red had
been used to 3 considerable extent in
dying Turkey-red, and produces q more
beautiful color than madden, its general
introduction could not be predicted, since
it Is more expensive than madden. The
discovery of q shorter and cheaper
method of producing this pure and
beautiful color is claimed by Geyer, by
which the operation Is completed in
about one third the time, and at twenty
per cent. less than the ordinary Turkey
red, and without any sacrifice of purity
or beauty.
jerome Jones, who is connected
with the glass industry of New England,
recently stated, after his return from
Europe, that the glass works there were
nearly idle, and the proprietors admit
that American makers have attained q
degree of excellence that has practically
cut them off from this market. The
glass works of New England, he OBJ
served, produce articles which in qua Ii
| ty, design, and engraving are equfl to
any made abroad. The New England
| glass company, Mr.. Jones said inciden-
| tally, paid an average dividend of 10 pen
cent. during the past forty years, but
| had earned no dividend in the last two
| years. The contemplated winding uI
of the company has, however, been post.
| pOned for further consideration.
During the late cholera epidemic
/ In Vienna, a new remedy, called cam
| phorein, was used with great success IN
| the hospitals. 1t is prepared simply by
| passing chlorine gas into pure turpen-
tine oil until saturated; it gives thick,
| heavy, oily fluid, of brown color, with
a strong smell of chlorine. This is freed
from muriatic acid by washing with
water. This remedy is applied by plac.
! ing portion In fat vessel and holdina
it to the patient to inhale. The results
attending this method of treatment are
regarded as indicating that oil of tur-
/ pentlne Is the best absorbent of chlorine
| gas, and that, therefore, it can be en-
| ployed with advantage In operations and
other cases where chlorine is to be evan
Grated In large quantities.
Investigations into the physioloei
cal effect of compressed air upon the
human body have brought some inter
esting facts TO notice. It appears that
some divers IN German mines noticed
below water a giddiness, and pains IN
eyes and ears, at a depth of only sc
feet, though many have descended ovel
40 feet. Prof. Romeaux, of Stras.
bourg, supposes that the blood gases.
carbonic acid, nitrogen, and oxygen, are
strongly compressed by the pressure OF
the lungs and blood vessels, and when
this pressure suddenly ceases they al
once expand and act Just as air bubbles
which are introduced in the air vessels
namely, they cause, pains, fits, or death.
This view has been confrme d by various
experiments, and the conclusion is that
diver can be exposed without danger
| to a pressure of five atmospheresS75
pounds per inch-or $50 feet of water,
while at $50 or go feet danger is imui-
nent. Under all circumstances. it is
well established as a principle that only
perfectly healthy persons should be ad-
mitted to work in highly compressed air.
