SCIENCE AND INDUSTRY.


An English inventor offers a systcm
by which coal gas compressed to one
eighth its natural bulk can be carried
about and utilized as an illuminant when
desired.
1t has been found by scientist that
red sealing-wax looked red in gaslight
and dirty white color in the light OF a
spirit lamp. This opens wide field for
the study of colors.
"A Sydney, Australia, paper says
that one of the wool companies there
has burning machine, recently i'm
ported from America, which effeetually
removes all burrs and other foreign mat
ter from sheep skins.
The council of hygiene in Paris, it
is said, is about to take steps to suppress
the use of old magazines and newspapers
for wrapping up food. The Austrian
government has prohibited the use Of
such papers and also Of eolored papers
to inclose articles intended to be eaten.
American inventions have cheap
ened and facilitated canal construction,
both as to excavation and locks, to such
an extent that the Nicaragua Canal will
be completed in half the time and at
half the cost that the same work would
have demanded fifty years ago.-Inven-
tive Age.
Prof. Mosso, of Turin, finds that
the blood of eels is poisonous when in
jected into the veins of dogs and other
animals, and that an eel weighing five
pounds contains poison enough to kill

however, when taken into the stomach,
and the poisonous properties are de-
stroyed by heat.
Experiments made by DIR. Vasilieff,
Of st. Petersburg, show that the boiling
of milk is not without its disadvantages.
The experiments were conducted ON six
young men, three of whom received
boiled and three natural milk. DIR.
Vasilieff's conclusion was that, as re-
CARDS nutritiousness, boiled milk repre-
sents decidedly inferior dietetic arti-
Gle as compared with raw milk.
AT recent meeting of the Geologi-
cal Institute at Vienna, areport was read
on the remarkable fall of meteorites OBJ
served in December last at Jelica, in
Servia. The meteorites fell over an
area of elliptical form, spreading from
the Jelica Mountains toward the river
river Morawa, and inclosing several
villages. The area is five miles long
and about three in breadth, and there
fell upon it twenty-six meteorites,
weighing in all nearly eighty pounds.
1t is now some twenty years since
M. Falb, an Austrian scientist, first sug-
gested the possibility that the moon
may act upon the great ocean of molten
matter beneath the earth's crust exactly
as it acts in producing the tides of the
external ocean of water. He now con-
siders that the reality of such action is
proven, and that the earth's crust is se-
verely strained and more or less warped
and broken at the times the theory
would indicate. 1t is during the periods
of greatest strain resulting from the
moons attraction that earthquakes ap-
pear to be most likely to occur, and that
gases seem to be forced into coal mines
to such an extent as greatly to increase
the explosions.
"A London physician and surgeon re-
Gently analyzed man and gave the re-
suits to his class in chemistry. The
body operated upon weighed 154.4
pounds. The lecturer exhibited upon
the platform 23.1 pounds of carbon. 2.2
pounds of lime, 1913 ounces of phos-
phorus and about one ounce each Of
sodium, iron, potassium, magnesium
and silicon. Besides this solid residue
DR.. Lancaster estimated that there were
5,595 cubic feet of oxygen, weighing 121
pounds; 1O5, 900 cubic feet of hydrogen,
weighing 15.4 pounds, and SO cubic feet
OF nitrogen in the mans body. All of
these elements combined in the follow
ing: One hundred and twenty-one
pounds of water, 1875 pounds gelatine,
1872 pounds fat, S.s pounds fbrin and
albumen and ~ pounds of phosphate Of
lime and other minerals.
