Gas has been successfully intro
duced as an illuminant on the street
cars of the British metropolis. The
holder, which is charged at the end of
every night trip, Is placed under the
seats.
Metallic pens were first introduced
for sale about 1903, though iron pens
are mentioned in 1855. Up to 1885. or
thereabouts, quill pens were almost uni
versally used. Now they are rarely
seen.
"A dark green and blue marble vein
has been discovered along the Shawan-
gunk Mountains, New York. 1t Is of q
very fine grain and easily worked. The
stone throughout is veined with dark
lines. As soon as the proper leases are
perfected the quarry will be worked, and
1t promises to be bonanza.
The Oil and Drug Ne,os says that
nearly bald servant of Mr.. Stevens, q
British Consul, used, after trimming
lamps, to rub his hands on his head,
and after three months had a much
finer head of glossy black hair than
ever before. Mr.. Stevens tried the ex-
pertinent on animals which had lost
their hair, with equal success. The
petroleum should be of the most refined
quality, and should be rubbed in vigor-
ously and quickly with the palm Of the
hand, six or seven times, at intervals
of three days, except in the case of
horses tails and names, when more ap-
plications may be needed.
DIR. Anat says that sea bathing
s'has proved of great benefit in many
cases of disease of the eye. The i'm
provement appears to be due to two
causes: 1. The influence which such q
course has upon the general health by
curing anamia and elevating the tone of
the system, since sea bathing Is in the
highest degree restorative. 2. Sea wa
ter and occasionally, also, the atmos-
phere of the sea has local irritant ac-
ton which should be watched, since il
is most serviceable when there Is q
chronic, torpid and indolent inflamma-
ton, while It is exceedingly dangerous
when the Inflammation is Of the acute
kind"
The common idea that volcano Is
a burning mountain, from the summit
of which issue smoke anu flame, Is de-
clared to be erroneous by Prof. Judd, Of
the Royal School of Mines. In q work
lately published by him on this subject,
he asserts that the action of volcanoes

Is it necessary that they should be. On
the contrary, according to Prof. Judd,
the volcano hole is very often not on the
summit. but on the side, sometimes OF
the base of the mountain or hill, and 1t
sends forth steam rather than smoke
the supposed raging flames being simply
the glowing light Of q mass of molten
material reflected from these vapor
clouds. This work claims to be the re-
suit of the latest and most scientific in
vestigations of the subject In all coun-
tries.-Chicdgo Tribune.
"A steam generator has been devised
on plan by which, at each stroke Of
the piston of the engine, certain guam
tity of water is projected against two
strongly heated metal plates, the steam
so produced going directly into the cyl
inder-an arrangement by which not
only special generator, but also the
valve system for the entering steam, Is
superfluous. In a description given Of
this mechanism, the vaporizing surface
is said to consist of two metallic cones,
one within the other, with an interval Of
about 0.04 inch between; the hollow
space is divided into two chambers, each
Of which Is connected with one side Of
the cylinder; and the gases play first on
the inner surface of the double cone,
then on the outer. This arrangement,
rs far as tested, has given quite satisfac-
tory results.-N. Y. Sun.
