SGlENCE AND INDUSTRY.

Gas has been successfully intro
duced NJ an illumnant 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 We're first introduced
for sale about lSl;, though iron pens
are mentioned in l6>j. Up TO lS}j. or
Whereabouts, quill pens We're almost uni
vcrSally 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 a
very fine grain and easily worked. The
stone throughout Is vcincd with dark
lines. As soon rs the proper leases are
perfected the quarry will he worked, aud
1t promises to lie a bonanza.
Tho Oii ami DruJ NcycS says that Il
nearly bald servant of Mr.. Stevens, Il
British Consul, used, after trimming,
lamps, TO rub his hands on his head,
and after three months had Il 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 he of the most refined
quality, and should he rubbed in vigor-
ouSly and quickly with the palm of the
hand, six or seven times, at intervals
of three days, except in the ease of
horses tails and names, when more ap-
pliGatiOnS may he needed.
DR.. Amat says that sea bathing
"haS proved of great benefit in many
eases OF disease of the eye The inn
proNcmcnt appears to be due to two
causes: |. The Influence which such n
course has upon the general health by
curing anarnia and clcvating the tone of
the system, since sell bathing is i'll the
highest degree restorative. ,. Sea wa
ter and occasionally, also, the atmoS-
phcrc of the sea has Il local irritant ac-
ton Which should he watched, since it
is most Serviceable when there is Il
chronic, torpid and indolent inllamma-
ton, while it is exceedingly dangerous
when the Inflammation is of the acute
kind"
The common idea that n volcano is
Il burning mountain, from the summit
Of which issue smoke and flame, Is de-
clared to he erroneous by Prof. Judd, of
the Royal School of Mines. In work
lately Published by him on this subject,
he asserts that the action of volcanoes
is not due 10 burning or combustion, nor
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 ut
the base of the mountain or hill, and it
sends forth steam rather than smoke
the supposed ri"il.. flames being simply
the Glowing li.h' of Il mass Of molten
material reflected from these vapor
clouds. This work claims to be the re.
suit OF the latest and most scientific in
veStiTa,ions of the subject in all coun--
tries. Chintyo 1ii'uHe.
A steam generator has been devised
on Il plan by which, at each stroke of
the piston of the engine, a certain qtan.
tity of water is projected against two
strongly heated metal plates, the steam

Under III arrangement by which not
only Il special generator, but ais" the
valve system for the entering steam, is
supcriluous. In y 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 o.oi inch between; the hollow
space is divided into two chambers, each
