Professor A. S. Herschel reports that
ne has found substitute for the mega
tive or ygen-bearing plate Of the
Faure accumulation. 1t is indestructible
and highly efficient, but it is not so
cheap as that which it is intended to
snpersede. II consists of platinum foil
which had been cooked at high heat
with lampblack for some days in q pot
terry kiln until its smooth surface be-
came thereby roughened with dull,
drossy coat The process of forming"
the cooked platinum plate, as well as Of
charging and disSharging it, exactly re-
sembles the usual processes with lead
en- one.
Good work from human beings, just
as from machinery, requires good treat
ment, and the finer the quality and the
greater the quantity of the work, the
larger must be the outlay. Build fac
tories that supply pure air, and the en-
ployes will produce more; but they will
ask for more pay, because they viii con-
sumo more food, and cannot live on low
wages. A donkey can exist on thistles.
OF course, and give donkey return;
but a race-horse cannot beplaced on the
same fare with profit to any one.
From the bones collected by M. Broea
and those contained in the Museum of
the Anthropological Society of Paris, it
would seem that early man had to bear
much the same osseolis LESSONS as mod
ern man in infancy and advanced years.
But what strikes me with surprise are
the numerous instances of trepanning
and OF well-consolidated fracture, show
ing that our remote ancestors were not
so ignorant of surgery as some of their
descendants may, not unreasonably,
have supposed.
The method adopted or recommend
cd by M. Jacquelain for making pure
carbons suitable for ready electric light
ing is as follows: A current OF dry
chlorine is passed for thirty hours on
several kilogrammes of crayons of re-
tort-carbon heated to bright red, and
afterward letting carburet Of Hydrogen
circulate among the carbons for five or
six hours. He has other methods for
preparing the carbons, but this seems
TO be the best.
A micro-telephone has been used with
success in discovering underground wa

may not those persons who used "divin-
ing rods to discover places where wells
could be dug have been possessed of an
unusually sensitive power of hearing.

Whether American salt meat can con.

cussed in paper by M. Colin and read
before the French Academy of Sciences,
The conclusion arrived at was that the
meat in question, as now imported into
Europe might in very rare cases trans

In an anthropological paper, M. Sab

pursued or from the physical nature Of
the particular region they inhabited.
In order to make good printing ink,
which will not give forth disagreeable
smell, DR.. Brackenbush, of Berlin, dis
solves forty-fve parts of fine resin in
twenty-five parts of parafline-oil by
heating them to eighty degrees, or by
incorporating them mechanically at the
ordinary temperature, and when this
latter operation is complete fifteen parts
of lampblack are added
A solution of chloride of lime, cam.
phor, and glycerine is recommended as
u disinfectant, but it is difficult to see
how it can take the place of other very
efficient and cheaper agents now in the
market, which leave no smell whatever.
Tan-bark, ground, compressed and
