New and rich discoveries of lead, said
to be the richest mines yet discovered in
the Southwest, have been made at Baxter
Springs, Kan.
ACCORDING to a return recently issued
there are at the present time about forty
new vessels in course of construction for
the British Navy. They vary in size from
the heavy iron-c clad of II ,1G5 tons to small
torpedo boats only eighty feet long. The
cost Of the whole is set down at "a $40,
900.
THE result of counting the persons Wis
iting public houses in Cork on Sunday
gives the following rough estimate: There
are about 600 public houses in the city,
and the number OF persons visiting them
between 30 and s 80 p. m. is computed
at 5000. As many as 400 were seen 60
ing into one public house.
The dock laborers at Liverpool, to the
number of 10 900, have mcmoralized the
Dock Board, asking them to abolish the
use of steam engines in the discharge of
ships Cargoes, the mems argument being
that machinery diminished the demand
for manual labor. The Dock Board have
informed the memorialists that they can
not comply with the request.
WHEN small pieces of camphor are
placed on the surface of water ii is known
that they turn about with the most capri
cious movements. This phenomenon has
lately been studied by NJ Lcscmur (of the
Chemical Society Of Paris in number of
other bodies He arranges in two classes
the substances that are endowed with the
"epipolar force" ~ Substances insolu-
bic in water. Once the spreading out has
occurred, all movement is arrested and
the movement of any other body is sus-
pended fixed oils, fatty bodies, etc. (2.)
Substances soluble in water The super
fetal layer produced is dissolved or
yolatilizcd with more or less rapidity
The movement is continuous. The satu-
ration of the liquid and the surrounding g
atmosphere causes all action to cease
(camphOr, acctc acid, essential oils). The
phenomenon is one of capillarity, or of
the superficial tension Of liquids.
On the eastern coast of Greenland, in a
wild and barren locality, an extensive de-
posit Of the mineral known as kryolite
was found few years ago. A large Phil
adelphia firm of manufacturing chemists
who knew of the discovery kept quiet
about it until they obtained the ownership
Of the whole tract of land from the Dan
ish Government, when they began active
mining operations. As the total supply
of the mineral in the whole world, apart
from this great Greenland deposit, is very
inconsiderable, the Philadelphia house
have a complete monopoly of the busi-
ness. They have already imported a
dozen cargoes, all at the port of Philadel-
phia, and the total quantity thus brought
is very great. The larger part is used in
their own chemical works. During the
year ending June 30, 1874, the value of
the firms importatiOns Of Greenland kry-
olite, all entered at Philadelphia, was
$17,S70. In the succeeding month of
August they brought S14,S66 worth in
September, $1S,5S7 worth; in October,
$9,0S7 worth; in November, S1S,071
worth. The importations thus far are
valued at over $4,000. Kryolite is a soft
magnetism mineral. Its principal use is
in the manufacture of EPSON salts, which,
it is well known, are employed largely in
print works and other manufactures, as
well as by druggists. In England, where
Epson salts are used more than in this
country, the material employed in their
manufacture is sometimes magnesite and
sometimes kaiserite, both of which are in
terior in quality to kryolite, and are an
nua ly becoming dearer and more diff
cult to obtain Cincinnati Trade List.
