Gastric juice from dog has proven an
effective remedy in various severe and dam
gerous stomach troubles.

Vegetarians will be interested in a new
food, claimed to resemble ordinary meat ex-
tracts in every respect, that has been OBJ
tanned from malt and hops by Mr. c.. O'Sul-

Gently inspected blind eel that has lived
In fresh water well of Helpringham, Eng
iand since 1924, and has been periodically
examined. 1t is eighteen inches long has
two large scales over it's sightless eyes a
remarkable arch in its back, and moves al
ways in circle, even when taken from the
well.
In experiments with the compressed air
pipes of Westphalian coal mines. Mr.. H.
Schab has found that the greatest distance
to which the sound Of the voice could be
conveyed in a straight pipe was between
1oOO and 1,7OO feet For moderate distances
a pipe or about twenty inches in diameter
gave the best results, slightly larger one
being better for long distances.
After study of more than eleven years,
DR.. c. Braun, Hungarian astronomer, has
completed a new determination of the mean
density Of the earth, which he finds to be
662I65 times that Of pure water. This agrees
closely with the best result by Prof. Boys.
The delicacy of the torsion balance used
was increased by Enclosure in a glass globe
from which all air was exhausted.
The quick spelling Of fresh meats is
thought by a Danish zoologist, August
Fjelstrup. to be mainly due to decomposi-
ton of the blood. To insure better keeping,
he stuns the animal by revolver shot
without injuring the brain, bleeds it by cut
ting down to the heart and opening a VEN
tr1cle, and then, with a powerful syringe,
inJects briny solution through the other
Ventrlcle into the veins of the body. This
method Of preserving beef which is speedy
and effective, was adopted in a Danish
slaughter house several months ago.
A self-maneuvering model yacht, about
five feet long, is a mechanical novelty that
is being exhibited in England by Mr. Her
bert Consterdine, a Lancashire mechanical
engineer. This remarkable little craft-too
small, of course, to carry sailor-goes out
for a cruise and returns home to her COM
mander at or near the point of departure,
all the operations of lacking, letting out
sail, steering etc, being automatically per-
formed. The distance Travelled on each tack,
as we'll as the number of tacks, can be reg
ulated to suit circumstances. The machin-
cry. is original but simple, the length of
each tack is controlled by the log, and the
only motive power is the wind.
A new microbe producing disease in rats
has been discovered by DR.. Issatschenks,
bacteriologist of the Russian government.
An epidemic having appeared among the
rats kept in the laboratory for experimental
purposes, bacillus was isolated from the
liver and spleen Of the affected animals,
and incubation with this proved extremely
fatal to both rats and mice. In food also
the organism invariably destroyed rats in
eight to fourteen days and mice in four to
eight days. Attempts to make practical
use OF the new microbe as a living rat poi
son have given no very encouraging results
thus far, but the efforts are being con-
tinued. Pigeons and rabbits are apparently
not affected.
