Professor Maisch says that direCtan-
tidote to the poisonous effects of the inhala-
| ton of chlorine is sulphuretted hydrogen,
liberating sulphur. The professor has tried
it himself after accidentally. inhaling chic
rine, and obtained immediate relief. The
same remedy would doubtless be effectual
In the case Of bromine poisoning.
Our nearest planetary neighbor is be-
| ing mapped out for our inspection and
| study, on scale of 200 inches to the
moons diameter. The work has been I'M
deytaken by an English scientific body, and
two sections just completed comprehend
two areas of twenty four superficial de-
grees each, which are equal to 17,888
square miles in the two. On these sec.
tions the plains, craters, mountains, valleys
and other objects are laid down in outline,
each known object being referred to in the
tezt accompanying the map.
| The Kinsington Museum Is to be recipi-
ent of measuring machine demonstrating
the one millionth part of an inch. This
| instrument and three original true planes,
are to be perpetually preserved, and a suf
| ficient endowment has also been made lor
| providing funds for the delivery of lectures
| explanatory of such Instruments. The do
nor, Mr.. Whitworth, of ordnance notorie-
| ty, says their Importance will be manifest
when 1t Is considered that the value of
every machine, when made of the best ma.
teriaI, depends on the truth of Its surfaces
and the accurate measurement of its parts.
Written telegraph dispatches are trans
mitted from the central telegraph station
In Paris to various other points of business
through iron tubes thrco and half inches
in diameter laid down not very far under
the surface. AT each station there is res
ervoir of water COMPRISING by It's weight
a reservoir of air beneath it, Tho tele-
grams are placed in cylinder fitting the
tube air tight !; the compressed air Is turned
on, and the cylinder with Its roll of des-
patches lis shot through to the next station,
or, if by any chance it sticks fast at any
point, the water from the reservoir Is lei
In, and by the fall of the water the point
of stoppage is marked. The system is as
simple as 1t Is economical.
MIR. Weber, one of the saoans OF Zu-
rich, Switzerland recently examined the
stomachs Of a number of moles caught In
different localities, but failed to discover
therein the slightest vestage Of plants or
roots; whereas they were filed by the re-
mains of earth worms. He shut up sever
al of these animals in a box containing
earth and sod with growing grass and a
smaller case Of grub or earth worms In
nine days two moles doyoured BAL white
worms, 1913 earth worms, 25 caterpillars,
and dead mouse. Fed with mixed diet
of raw meat and vegetables the moles ate
vegetables exclusively were dealt out to
them, in twenty-sour hours both died of
starvation.
M. Heurtebise communicated to a late
number of mention plen for produc-
ing and economically employing hydrogen
gas, which is both new and valuable. He
places charcoal In retort and raises il to
red heat, then passing q stream of car
bonic acid over it, each molecule of the
acid absOrbs two atoms of carbon forming
two molecules Of oxyde Of carbon. In an
other retort heated red hot he passes two
currents, one thus obtained and another of
superheated steam, when two atoms of car
bonic acid and two equivalents of hydro
gen gas result The carbonic acid gas is
again passed over the heated charcoal and
four equivalents of hydrogen are obtained.
A continuous action is thus Kept UP, with
a steady supply of hydrogen, =, !. ''a9 T.,
