Paper manufacture is one of the
chief industries in Corea. The paper is
made in the most primitive manner from
the bark of a tree which is indigenous
to the country and which is closely al

The rate of progression of storm
is often fifty miles an hour, and series
has often been traced in direct line
from north to south distance of 400
miles. The average altitude of thunder
storms has been found to be not over

Pieces of natural iron have been
found in Arizona, near the Canon

hardness. and contain small cavities
which are filled with black substance
in which are diamonds. some half "A

of natural iron appear to be Of mcteoric
origin. The occurrence Of the diamond

The American Cotton and Wool

Contemplating sheet zinc for build
ing purposes has been tried with con-
sidera bic success in Germany, the zinc
combining well with the copper. The
zinc is cleaned with soda and purified
by a weak acid bath. In twentv-four
parts of water one part of refined YER
al ,Nf 6
tar are dissolved. and the mixture is
heated to the boiling point, when three
to four parts of Spanish white are
added. The latter is decomposed ana
precipitated as lime tartrate. The
dark-bluc liquid. after filtering, can be
used as a bath for the sheet zine or for
the production of copperplating paste
DR.. Lauder Brunton in the course
of ii recent letter on "Mastication" at
st Bartholomew hospital. made use
of the following remarks: Il think it
was magnificent stroke of genius on
the part of thu president of the ROYAL
College of Physicians, Sir Andrew
Clark. when he informed Mr. Gladstone
that he had one mouth and tnirtv-two
teeth, and that for every mouthful Of
food he took every tooth should have a
chance, SO that he should take thirty
two bites to every mouthful And"
continued DR.. Brunton, IF the patient
has lost some of his teeth he should
allow two bites ocevery missing tooth,
and even that will not always do if
many teeth have gone"
The California Academy of Sciences
has become the possessor of an unusu-
ally sound skeleton of rnachianeetes
glaucus, or California gray whale. 1t
is forty-iive feet III length, and has
twenty-siX ribs, seven feet on the curve,
and two great scapule. resembling
broadaXes. The jaws are nine feet in
length. The California gray whale has
no teeth. but is provided with baleen.
or "whalebone," row of bony sub
stances resembling brushes. These sift
the water and catch the animalcul;e
floating in it, the only food of this class
of Observation-Disclosures News.
The resources OF the lecture-room
are decidedly increased when Prof
Dewar was able. in lecture on chem
istry in London lately, to produce
liquid oxygen in the presence of the
audience literally by pints, and to pass
liquid air about the room in claret
glasses Oxygen liquifies at about 80
degrees below zero. and air at 343 de-
grees below zero. If the earth were
reduced to a tempara ture so degrees
below zero it would he covered with
sea of liquid air thirty-five feet deep.
Prof. Dewar's process of liquefying
oxygen and nitrogen was with IA hun
dred pounds of liquid ethylene and fifty
pounds of nitrous oxide, with the aid of
two air pumps and two compressors
driven by steam.
