SCIENCE.AND INDUSTRY.

The first attempt to manufacture
beet sugar in Melbourne, Australia, has |
proved Improbable.
At Limoges a gunsmith has invented |
a breech self-loading carbine which dis |
charges twenty bullets a minute. Tt |
has been submitted TO the French mill |
tary authorities.
Nashville, Tenn, recently cele- |
brated the success attained by the to- |
bacco industry there, the quantity of |
tobacco received having increased fiom
900 hogsheads three years ago to 300
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
ly purchased tobacco in the larger cities.
During the first four months of this

"A new hot-blast oven is in use in
iron-making at Troy. 1t utilizes as fuel

1t is intended in Paris to construct
| street railroads on nine distinct routes,
making in all about thirty-two miles of

bonded loan of 81, 900, 600.
Although the new alizarine-red had

| beautiful color than madden, its general

discovery of q shorter and cheaper

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 a
degree of excellence that has PR ctically
cut them off from this market. The
glass works of New England, he OBJ
served, produce articles which in qua IL
ty, design, and engraving are equal to
any made abroad. The New England
glass company, Mr.. Jones said inclden-
tally, paid an average dividend of 10 per
cent. during the past forty years, but
had earned no dividend in the last two
years. The contemplated winding up
of the company has, however, been post

During the late cholera epidemic
IN Vienna, new remedy, called cam
phOrein, was used with great success III
the hospitals. 1t Is prepared simply by
passing chlorine gas into pure turpen-
tine oil until saturated it gives a 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 a portion in a fiat vessel and holding
} it to the patient to inhale. The results
attending this method of treatment are
regarded as indicating that oil of tur
, pentine Is the best absorbent of chlorine
, gas, and that, therefore, it can be EN-
ployed with advantage in operations anC
other cases where chlorine IS to be egap
Grated in large quantities.
Investigations into the physiolog /
cal effect of compressed air upon the
human body have brought some inter
esting facts to notice. 1t appears tina
some divers in German mines noticed
! below water giddiness, and pains II
l eyes and ears, at a depth of only 81
I feet, though many have descended owe
= 100 feet. Prof. Romeaux, of Srras
e bourg, supposes that the blood gases
! carbonic acid, nitrogen, and oxygen, ar
p strongly compressed by the pressure o
D the lungs and blood vessels, and whel
this pressure suddenly ceases they a
once expand and act Just as AIR bubble
which are introduced in the air vessels
namely, they cause, pains, fits, or death
l This view has been confirm d by variou
experiments, and the conclusion is tina
T. a diver can be exposed without DANCE

, pounds per inch-or 100 feet of water
while at go or go feet danger is immi
