SCIENCE AND INDUSTRY.
Additional evidence on the subject
of the supposed heat from the suns
rays is furnished by an experiment
recently reported in France. balloon,
with registering instruments was sent
M a distance of ten miles above the
earth's surface, where the temperature
registered was found to be lo4 degrees
Fahrenheit.
The japanese are now making ten
mis- rackets, and some of them are inn
ported to the United States The work
manship is uncommonly fine and all
the materials look durable. Europeans
in Japan have long played tennis, and
the game originated good deal nearer
Japan than Europe. 1t was the Badmin-
ton brought to England by East Indian
travellers
DIR. Lewis Swift, who is credited
with nine distinct comet discoveries,
thinks that comets are composed OF
little particles as small as kernels OF
wheat, each with its own atmosphere
surrounding it," but this is about the
extent of his knowledge on the subject,

one way and sometimes the other" he
says, 81 do not think any one knows
-Krupp of Prussia claims as the re-
suit of experiments that while only 10
to Is per cent of heat units are utilized
| in the modern steam engine, If the coal
is powdered to an impalpable powder
and exploded in cylinders, after the
manner of an ordinary gas engine, 75
to so per cent. of the heat units may
be realized.
1t is surprising fact that of all the
organic salts of our body we only take
one-sodium chloride, or common salt
from inorganic nature and add it to
our food. All other salts are present
| in organic foodstuffs in quantities SUI
ficient to our requirements; we have nc
need to seek for them elsewhere.
Copper must have been one of the
earliest metals known, worked and
valued in human industry. 1t ranks
second to silver in malleability and due
tility, or third as compared with gold,
which is the most malleable metal
known, and ranks next to iron in ten

metal, native in many parts OF the
world, it often lies at or near the sur
face of the earth.
"A series of chemical tests, instf-
tuted at the instance of Pomeranian
dairy farmers, showed that fully twen-
ty-five per cent. of the butter sold in
Berlin was adulterated with margarin.
The amount of the admixture ranged
from 80 to 100 per cent. The conclusion
was that the loss to German dairy far
mers on this account could not be less
than ten thousand dollars per day. A
movement has been started to procure
legislation against the fraud.
The vertebrate of snake are fitted
together with a sort of ball and socket
articulation, which, however, is capa-
BILE of motion only from side to side. A
snake moves by propelling himself or
the points of the scales, which, to him.
answer the purpose of ribs. A snake
does not climb tree or bush by coiline
around it, but by holding on with the
points of its scales. A snake on pane
of glass is almost helpless.
According to the census the United
States produced 457 100000 dozen Of
eggs in 1879, and 81 100000 dozen in
1889. These figures are probably under
J the mark At the figures given, how
ever, the annual egg product OF the
United States amounts to 100000, 900
If to this we add the value of the poul
try sold we shall obtain a pretty higl
figure for the annual output of this de
partment. One authority has placed i

crop of the United States amounted t.
