The Journal d Ocuhstiquei is the author

A factory has been built at Osaka

On the railroad connecting Revel ard
Marty lie Roi, France, it is said that the
experiment Of running the locomotive by

Speaking Of the use Of pain, the Lancet
observes that generally it may be set
down as an axiom that the chief and
obvious service Of pain to humanity
is a deterrent and warning SEN
sation to ward off danger. Pain,
however, has secondary and educational
value as regards the mind and temper,
and some sorts Of pan may be specially
designed for this purpose. In this view.
also, pam has practical interest, because
the development Of mind is a process
governed by natural laws of which science
Is perfectly competent to take heed.
The nitrate of lead is now recon-
mendel in the medical journals as
scarcely second to any other substance,
in point Of cheapness and efficacy, as a
deodorizer- To prepare it for it
simply necessary to take, for ordinary
purposes, half ORA Inn OF the nitrate,
dissolved in pint or more Of boil Nc
water, dissolve about two drachms OF
common salt in a pail Of water, pour the
two solutions together, and allow the
sediment to settle. TO purify and sweet
feted atmosphere immediately, dip
cloth IN the liquid and hang it up IN
the apartments.
The electric light continues to grow in
favor. Arrangements are making to IL
Illuminate the British House of Lords by
it. An English scientist has been lectur-
ing before the Society of Arts on the sub
jeGt and demonstrated that the electric
costs from a bait to twelfth as much as
the gas light. He does not consider the
two in direct competition yet, but re
CARDS the electric light as peculiarly fit
ted to do just what gas is incapable OF.
At the Paris Exposition great attention is
being paid to illumination, and the cleo
trio light IS being experimental upon
and tested in various ways.
The Smithsonian Institution is prepar-
ing for the publication of an exhaustive
work on American Archaeology, and has
sent out a circular asking ali who have
original information bearing upon any
phrase Of tie subject, to communicate it
without delay to the Institution. The
work will be accompanied with series of
maps showing the localities and distinc
tive characteristics Of ancient mounds
and eart}t-works; she'll heaps; caves and
cliff dwellings,, masonry; sculptured slabs
or carved images; inscriptions and rock
paintings; graves and cemeteries; aborig-
inal quarries and salt-wolks; caches, or
deposits Of objects in large quantities;
workshops, or places of ancient aborigi-
mai indu etry; ancient roads or trials; and
reservoirs and acqueducts,''
Mr.. f. PePpard is t G inventor of a
curious contrivance for awakening a
sleeper at u given hour. The apparatus
is to be affixed 10 an ordinary clock, it is
SO arrange that when the hour-hand of
thu clock touches bottom, an electric
SiiSulS lPlctCN> lHS
passes over the button without effect
There are series of holes for the different
hours, into any one of which the button
can be pushed, according to the time
selected for awakening. The completion
of the electric circuit may ring bell, or
sound any other Of the numerous ordinary
methods OF alarm. But this con-
trivancc has a vet more effective method
for arouslng deaf man or any sleeper
who is willing beforehand to prepare
himself for shock. A bracelet is pro-
vided which can be put or the wrist at
the time Of retiring; to this, flexible wires
are attached and the electric discharge
will pass through it at the appointed
hour A man who could lie down to
pleasant dreams with such an apparatus
fastened to his wrist, would naturally
need the violence of an e'ectrlc shock to
awaken him. ChicngO Times.
