A simple method OF electroplating
on wood has been described by Mr.,
G. f. Barnes, who believes that the
process should be of considerable
| advantage in decorative work. The
article is saturated with copper sui
phate, which after drying-is con-
verted into insoluble sulphide by ex-
posure to current =. of sulphureted
hydrogen gas, and the sulphlde IN
turn is reduced to metallic copper
when the wood, lightly wrapped with
fine copper wire, is suspended for
some minutes in solution of com
mon salt at the cathode of suitable
current. A copper coating of any
desired thickness may be then given
in the ordinary plating bath, a silver
coating being finally added if desired

A study of the strange and little
understood abnormal growths OF
plants has heen made during the last
twelve years by NJ. Hugo de Vrles.
From seeds of the unnatural plants,
he has reproduced many descendants
of normal type, but sufficiently
large number of abnormal individu-
ais to prove that the monstrosities are
hereditary and result of disease.
The only anomaly not reproduced
in the succeeding generations was
the green given some plants by para
sites.
A sponge of honey in small pot
was carried by Greek nurses to
soothe childr an, said Prof Mosby in
late address to British antiquarians.
In the British Museum are two Greek
vases, eating from 700 B. c., that are
much like the later Roman feeding
bottles; and another old example is
a bow shaped terra Gotta vessel, with
a funnel rising from the middle of
the back. A feeding bottle taken in
1861 from an old Roman cemetary at
Canterbury was of bright, red, pol
ished ware, and had doubtless been
buried with it's infant user.

A vegetable origin of tuberculosis
has been suggested. The latest in
vestigator of the subject is NJ. Noel
Ter, who has found on an abundant
grass of France bacillus SO strongly
resembling the tubercle bacillus as to
give rise to the question whether the
two may not be one organism modi-
fed by environment.

Ceramic stone, or devitrified glass,
is attracting especial attention in
France. Large notwithstanding
broken bottles as raw material
been built near Lyons, and the pro-
duct has been under test as street
paving for several months, the manu-
facturers claiminf a durability greater
than ordinary stone at no greater
cost, with unusual freedom from ice
in inter and from liability to- collect
dust and harbor microbes. From a
report of the Central Architectural
Society of France, it appears that the
ceramic stone is simply glass brought
to special molecular condition by |
heat and hydralic pressure. 1t re-
tains the physical and chemical quail
tiles of glass, except the Transparent
cy, but appears like new substance,
fagstone, granite or
marble. 1t is given greater resist
snce to crushing, frost, heavy shocks,
and wear. This stone is already
made into blocks suitable for street
paving and floors, into limitations of
polished marble and mosaic, into1
panels, and into pipes
md tubes, and as building material
or houses and factories it is said to
20 lighter and cheaper than brick.

In new process of hardening
teel, the metal is first coated with a
mixture of whiting and varnish. It
8 then heated to cherry red, dipped
or few seconds in acidulated water
hen for a slightly longer time in
ape oil, and is finally laid in a cool
ng bath of rock oil or mixture of
