SCIENCE AND INDUSTRY.

DIR. Cathell, in the Maryland Medi-
cal Journal, advances the opinion bat
fasting during the long interval be-
tween supper and breakfast, and espe-
cially the complete emptiness of the
stomach during sleep, adds greatly to
the amount of emaciation. sleeplessness
and general weakness so often met.
Prof. Spencer computes the age OF
Niagara Falls at about $4,000 years. 1t
is now eight thousand years since Lake
Huron emptied into Lake Erie for the
first time The land has risen about
the outlet of Lake Erie, and if the pres
ent rate continues, in five or six thou
sand years the waters of the four up
per lakes will be turned into the Mis-
sissippi river drainage at Chicago
"A scientific authority states that
bv saturating bullet with vaseline its
fight may be easily followed with the
eye from the time it leaves the muzzle
of the rifle until it strikes the target.
The course of the bullet is marked by

! When the horse sleeps it is said
! that one ear is directed forward, why
! is not known. A writer inthe English
Mechanic thinks this is to guard against
danger, being a survival of their origl-
! nally wild habits. He says: Watch a
i horse asleep through the window of his
stable and make faint noise to the
! front. That ear will be all attention,
and probable the other will fly round
! sharply to assist. Now let him go to
sleep again, and make the same noise
to the left The forward ear still will
keep his guard, with possibly light
ming flick around, only to resume its
former position.
DR. McClintock, of the University
of Michigan, has performed expert
ments which indicate that eggs may
become affected with microbes before
they are laid. A healthy hen, after
repeated washings in sterilizing solu-
tions, was placed in a steriliZed cage.
AS soon as possible after being laid,
portion of her eggs were placed in
sterilized cotton and then in an incu-
bator All these eggs decayed and
swarmed with bacteria. The remain
ing eggs were taken as soon as laid.
and cultures were made from their con-
tents Some of these culture tubes de-
veloped; others remained sterile. After
some DAYS the hen was killed, and
with proper aseptic precautions culture
tubes were inoculated from various
portions of the oviduct. Most of these
tubes developed. 1t would thus seem
probable that the putrefactive bacteria
entered the egg in its passage down
the oviduct and before the shell was
formed
