TUNNELING HIGH MOUNTAINS.
With regard to the degree of tempera

Raymond says it is possible that work
can be carried on for short time at CO.
Ceutigrade, if the atmosphere is dry, but
not beyond 400 when the sir is saturated
with moisture.
TEMPERED GLkss.
Some, or rather most people, will re-
member the furore caused by the So
called tempered glass, invented by NJ.
De La Bastie, and the multiplicity Of
purposes for which it was said to be
eminently adapted. But the lamp CHM
neys, bakers, g., made of that material
had fatal facility of suddenly explod-
ing into thousand fragments, sometimes
spontaneously. It is now announced
that De La Bastie has made much I'M
provements IL his glass tempering pro-
cess that the quality OF the products is
immensely more durable.
NICKEL FOR CoMPAssEs.
At late meeting of the Academic DIES
Sciences, Nj. Warden made 8 sugges-
ton to substitute nickel for steel as 8
material for compass needles. NJ. War
don adopts a circlet OF the metal of 8
form similar TO thst devised by III.
Duchemin. When the apparatus was
submitted under the direction of the
Ministere de Ia Marine TO q comparative
trial with that of d. Duchemin, it was
IL e. &C.
cal purposes; for the oscillations of the
magnetixed circlet are extremely slow,
owing to the comparatively feeble inten-
sity OF magnetization of nickel.
DURATION OF LIFE AFTER DECAPITA-
TON.
Immediately after the execution of
the murderer Pruuier at Beauvsis, ex-
periments were made with the head Of
the criminal by q number of doctors,
among them DR.. Decaisne, OF the Insti-
tute, with the view of deciding the
question so frequently raised of the
duration of life after decapitaJion. A
report on the subject will be presented
to the Academy OF Medicine, but the
conclusions OF it win be that death is
instantaneous. TIE brain exhibited adj
covering it, which is generally observed
In lunaticg.
ANEW GAS MATERIAL.
At Baka, off the Caspian aea, the resi-
due ostG5EG left after the final dis5iilation
of petroleum is produced in such enor-
nous quantity that It's price is only
nominal. and much Of it is poured into
the SEA for lack Of slowing space or de-
mand. For years it has been the only
fuel used on board the war ships and
mercantile steamers Of the Caspian. It
is employed in cooking also, and for the
production Of illuminating gas. In the
latter case it is allowed 80 trickle slowly
into retorts raised TO q dull red heat,
pure gas with little graphite being the
result. Weight for weight. Gst0lki gives
four times as great volume Of gas as
ordinary Popaa5ar science Monthly.
CURING THE OPIUM HABIT.
Dr.. Osgood, who is the medical officer
of the hospital at Foochow, under the
care of the American board Of foreign
missions, gives the following So the
method which for some time has been
successfully pursued by him IL the cure
of the opium habit. /. Tie total, abso-
lutte discontinuance Of the use Of opium
from the beginning of treatment. 2. 4
trustworthy attendant TO be with TIE
patient Day and night for the first three
days. 3. Choral hydrate for the. first
three nights, If required. f. Good
food, milk, raw eggs Tin some cases., and
chicken broth in small quantities and
frequently. 5. In cases Of diarrhoea
give two drachm doses of mixture OF
equal parts OF catechu and tincture OF
ginger.
ECONOMICAL ILLUMINATING GAS.
According to the Journal of the
Franklin Institute, Mr.. e. Comnelin las
discovered a new industrial application
of hydrogen. He places retortg or tubes
of metal or refractory earthenwsre in
the arch OF furnaces or generators, in
hot-air apparatus or elsewhere, where
they are exposed TO red heat. They
are filed VITA charcoal, coke or cinders,
and small Jet Of vapor is introduced,
which produces, by decomposition or
decomposition, hydrogen, carbonic oxide
and carbonic acid gas. The apparatus
is thus raised TO red heat and steam is
obtained without expense. Each tube
which contains IS kilos (55 lbs Of ceke
yields 10 ten hours 100 cubic metres
1881 658 cubic feet) Of gas, which is
passed into a purifier and thence to a
gasometer It's illuminating power is
increased by mixture with the vapor
or gas Of volatile or solid hydrocarbons,
so IS to yield, st shout one-sixteenth
the cost, a winter and more brilliant
fame than that of coal gas.
eAED BATHS FOR RHEUMATIBM.
Many persons along the sea coast in
this country recommend and use sand
baths 10 July and August for the cure
of rheumatism. In Greece, near their
sea coasts, it is one of the sure remedies
used by persons affected with chronic
rheumatism, anchalysis, and chronic
