vised for use on a moving train which

Railroad authorities say that an or
binary locomotive has 800 horsepower

If man had been limited to the use
of his natural weapons of defense he

Professor Bonney says that fall of
fifteen to twenty degrees F. in the
average temperature would be suf-
ficient to account for all known glacia-
ton in the northern hemisphere.
At II recent session of the central

Air can be frozen at temperature
of 295 degrees below zero, and the
product, which can be handled and
felt, burns, SO to speak, with its ex-
cessive cold. Frozen air can be pro-
duced in any quantity, but it's cost,
$500 gallon, is likely to prevent a
large business.
The observations of twenty-five
years, made in the Bay of Bengal by
the Indian Government meteorolo-

Electrolytic experiments in connec-
tion with the manufacture Of beet root
sugar have proved to be so successful
that the principal French factories
and thirty three German firms have
decided to adopt the electrolytic pro-
cesses. 1t has been found that the
presence of one part of salt prevents
the crystallization of four parts of su-
gar, and by means of electrolytic os-
mesis the saline constituents of the
juices can be effectively eliminated.
