Experiments by an Italian physician
indicate that tuberculosis of fowls is
different from that of man, and is not
transmitted to the latter.
There are about $4,000, COO parts in

1t is stated on good authority that
the factories Of England, France, Ger
many and Holland produce about IT,
900, 600 pins daily. But where do they
all go to?
Seven varieties of fishes examined
by naturalists of the Challenger expedi-
ton are found totally blind in the deep
sea, but have eyes when inhabiting
shallow water.
The State geologist of New Jersey
says the coast of that State is sinking at
the rate of at least two feet in century.
| Other observers hold that the rate is
much more rapid.
More women in proportion to popu-
lation are employed in industrial occu-
pations in England than in any other
European country. Twelve per cent. of
the industrial classes are females.
"A large vein of pure white sand,
suitable for making glass, has been
found near Pittsburgh, Pa. The dis
covery will save the glass manufact-
urers of that city thousands of dollars
annually, as they have hitherto been
Obliged to send across the Allegheny
Mountains for their sand.

| gland is introducing a novelty in paper,
viz, paper file-hafts and tool-handles,
which are said to be practically indie
structible and much cheaper than wood
or malleable iron hats. Placed under
steam hammer, although they can be
flattened, they can not be split or
cracked.
"A sample of oranges plucked from
trees grown on the place of Thomas E
Halle, at Kanapha, Fla, are of the early
variety, just commenced to ripen, and
will weigh about one pound each. Mr..
Haile's grove covers several acres, and
the trees are so loaded with fruit that it
has become necessary to prop them up
The crop is simply wonderful.
-"Sometimes, writes correspond
ent of trade paper, 81 have had to
make holes in steel that was too hard to
cut or file easily. Then l make mix
ture that will cut hole. l mix one
ounce of sulphate of copper, quarter of
an ounce of alum, half teaspoonful OF
powdered salt, gill of vinegar and
twenty drops of nitric acid. This will
make hole"
chemist, believes 1--WE may reasonably
hope that chemistry will yet teach US to
make the fiber of wood a source of
human food" This fiber, as we'll as
that of grass and straw, is chemically
closely allied to starch, but is not al
tered like starch, in boiling water, yet
both the wood fiber and the starch can
be transformed into glucose. In short,
we may somo day be breakfasting on
sawdust porridge.
For some time past efforts have been
made to consolidate, and virtually place
under one management, the American
glass factories manufacturing tableware.
1t is announced that arrangements are
in progress by which at. least thirty-one
of the factories engaged in this line will
be united. Tho accredited agents of
the movement, while they give but lit
tie information, state that the capital
does not come from distinctively foreign
sources.-American Manufacturer
Aluminium and alloys are now pro-
duced in considerable quantities by
three distinct methods from certain
clays, corundum, etc. In one case the
! oli ,N4, ir
employed, in another the electrical
smelling furnace process, and in third
the direct smelling substitution process
is resorted to. The last-named method,
which has proved very successful, con-
sists in producing a chemical alloy
within a water-jacketed furnace and
metal fume condenser - without any
metallic sodium or electricity the
product being equaled by only one
other, which may be classed as the
solidified solution of one metal into
another.
"A Belgian che mist is said to have
devised a method of rendering fabrics
proof against tho ravages of decay for
an indefinite period. Noting the fact
that resin played an important part in
the wonderful preservation of Egyptian
mummies, he made numerous expert
ments with substances extracted from
birch bark, to which the peculiar aroma
of Russian leather is due. He found
that the green tar which is left over
after the oil used in tanning has been
extracted from the white bark of the
birch tree yields neither acid nor aka

forms liquid of remarkable fuidity,
which has the power of resisting when
dry the action of even alcohol. 1t is
claimed that this preservation possesses
the property of uniting with the most
delicate and brilliant colors and render
ing them apparently imperishable.
