power per annum, equivalent to a
total yearly saving of %, 600, 900 tons
which, at 7 shillings per ton, would
represent value of 9, 800, 600 saving.
AS the cost of the change would not
exceed 100000, sterling, the svaing
in coal would return 1876 per cent. If
the power were to be delivered as
electricity, the cost of change would
be 0,000, 900, but the gain in effici
ency and convenience would in many
cases equal the saving in coal.
Drafts over deep wells are usual '
due to changes OF temperature or
ba1ometric pressure, air being forced
in as the pressure rises and drawn out
when the barometer is falling. But
two wells in the Vicksburg jackson
limestone of southern Georgia have
shown the strange phenomenon of a
continuous in-drafts. This has been
investigated by Mr. S. W. McCallie,
who has found rapid subterranean
stream at depth of about 100 feet,
and it is supposed that the air is suck
ed in by friction and carried along
until the water rises as large spring.
Loss of sleep proves to be the curl
GUS effect that may limit mans
mountain clim bing. DR. Bullock Work
man mentions that in his camp in the
Himalayas at 10, 1858 feet, members of
his party we're kept awake by lack of
breath, and on doing off would
suddenly awake gasping. He con-
cludes that inability to sleep may It
self be sufficient to keep climbers
from going beyond $4,000 to 25, 900
feet.
The novel combination automobile
of M. Henri Pieper, the Belgian in
veDtor, is claimed to be an important
advance in several respects. The car,
which is know as the "auto- -mixte, :"
is equipped with gasoline motor, a
dynamo, and storage battery OF "a
Tudor cells having total weight of
$40 pounds. The gasoline motor is of
ordinary four-cylinder type, with a
magnetic gas throttle for regulating
the speed. When the gasoline motor
is running with light load, the dy-
namo acts as generator to charge the
storage battery, but on rising grades
and hard places it can be run as
motor on current from the battery and
its aid gives greater average speed
than can be had from simple gaso-
line machine of the same power. The
distance run is not limited by the
charge in the battery, as with the
electric automobile, while in case of
breakdown the battery can be depend
ed upon to run certain distance.
No special starting device is needed,
and speed changing gear and various
9th er devices are made unnecessary.
Chemists have been unable to OBJ
tain any extract having the proper
ties of gastric juice, and for number
of years attempts have been made in
France and Russia to secure the
natural material from the stomachs
of dogs or other animals. After long
experiment, DIR. Hepp has succeeded
in getting a regular supply from hogs,
thus creating a new industry on a
French farm. AT the age of three OF
four months, the animals are so
operated upon that their food does
not pass through the stomach, and a
gastric tistula is formed. Eating
excites the usual flow of gastric juice,
which, unmiXed with food, is drawn
twice daily from the fistula. The
animals are kept clean, receive the
best of food, and their health remains
perfect in spite of the serious change
in their digestive arrangements. The
which can be kept indefinitely, is of
great value in treating stomach dis
orders.
The plan of occasionally flushing
drains with petrol in water, to destroy
the eggs of house flies, has been
awarded a $4,000 prize by a Paris
paper.
Radium preparations cannot be ex-
tensively used in the treatment OF
disease, on account OF the great cost.
The radios activity impaired to such
substances as paper, fluids, etc., is
too feeble and feeting to be of use,
but DR.. Axmann of Erfurt, now
claims that his new product-which
thas been named radiophoI-is endow-
ed with quite permanent radio activity
of sufficient strength, and it is in
expensive. The substance is used OIL
the skin, in growths or cavities, OIL
tor coating surgical instruments. In
plates of pinhead size, it is held tc
the skin by some such means as plas.
ter or bandage, and it is allowed tC
remain for varying periods of few
hours to three days.
A barber-shop on hygienic principles
