increases the yield of milk, but that
violent motion hinders the process Of
milk secretion. Dairy farmers may
turn this remark to profit.
Sir Henry Bessemer has announced
that, by the use of very pure char
coal pig iron and its treatment by a
special method, Bessemer steel is
produced which on analysis is found
equal in purity to the highest brands
of steel made from blistered bars.
Captain c. E. Dutton, of the United
States Geological Survey, is now sue
cessfully prosecuting the investigation
of the basalt territory lying in New
Mexico to the east and south of the
area already described by him in his
reports on the Utah plateau and the
canon country.
The North of England correspond
ent of the Engineer says the use of
the electric light does not seem to be
increasing in the iron works of the
Cleveland district. There is every
reason to believe that this is due mere
ly to a temporary reaction, and that
very soon there will be a more gen.
eral employment of it than ever.
M. Vulpian has written on the an@s-
thetic action of the carbohydrate of
cocaine. He states that this an@s-
thetic is SO powerful that an aqueous
solution of one part salt of cocaine
and ninety-nine parts of water in
serted under the eyelids produces COM
plete insensibility of the cornea and
conjunciva in the human eye.
The first smelling works in Aus
tralia have commenced operations In
the newly discovered silver region of
MitchelPs Creek, near Bathurst The
scene of operation is called Sunny
Corner, and the district is believed to
be as rich in argentiferous ore as is
that Of the Barrier Ranges. Other
smelling works have been begun, and
the whole are under the direction of
miners who have had considerable ex-
perience in America.
Two important filters are described
In the journal de Pharnaacie et Cnemie.
The Chamberlain filter consists of
porous cylinder of ground porcelain
burned TO such heat that it is capa-
BILE of transmitting liquids, but not
solids. 1t is used in Pasteur's labora-
tory for separating microbia from their
culture liquids. Pasteur has found
that on filtering with it the most i'm
pure waters the germs of the microbia
can not pass through it. In the
Maigren filter the acting medium is
mixture of powdered hydrate of lime
and OF boneblack. This apparatus is
said to be capable of removing not
merely suspended but dissolved inn
ourieties.
A memoir by M. F. F. LIE Roux on
IN experimental demonstration of the
inversion of the electromotOr force
Produced by the contact of iron and
copper at high temperature, has
'een submitted to the Academy of
sciences, Paris. From the results of
everal experiments, conducted under
arying conditions, NJ LIE Roux con-
ludes that at about the temperature
f 1000 deg. Centrigrade an electric
urrent passing from the copper to
he iron heats the point of contact,
7hile cooling it at the ordinary tenn
erature. A knowledge of this fact,
ow for the first time demonstrated.

Glass has been in use from so re-
ote period of antiquity and has so
timately associated itself with the
rogress of civilization, that it is not
uprising to find improvements in
5 manufacture as often as the neces-
ty for them has arisen. From the
lintings found by Wilkinson at
it appears that the art
glass-blowing was known at least
200 years ago. Sometimes new pro-
sses in dealing with the raw mate
als have produced desirable and
metimes startling results. 1t is said
at some Anglo-German manufact-
ers have recently turned out glass
hard and tough as cast iron, and
at they intend to make of this hard
d comparatively light crystal stairs,
'eet lamp posts and gas and water
pes. 1t is thought that they can
Ike these and similar articles of
lss thirty per cent cheaper than
ey can make them of cast iron.

Society, Manchester. OF
