bands, lying in V grooves in the
pulleys, of no great acuteness, would give the greatest resistance with
the least variation of the coefficient of friction; the heat developed
being in that case neutralized by a jet of water on the pulley. It would
be quite possible with a pulley of say 3 feet diameter, and running at
50 feet of surface velocity per second, to have a sufficiently flexible
wire, capable of carrying 100 lb. as the greater load, Q. Now with these
proportions a brake of the form in Fig. 3 would, with a probable value
of the coefficient of friction, absorb 6 horse power. With a brake in
the form Fig. 4, 8.2 horse power would be absorbed; and with a brake in
the form Fig. 5, 8.8 horse power would be absorbed. But since it would
be easy to have two, three, or more wires side by side, each carrying
its load of 100 lb., large amounts of horsepower could be conveniently
absorbed and measured.

SEE'S GAS STOVE.

This stove consists of two or more superposed pipes provided with
radiators. A gas burner is placed at the entrance of either the upper or
lower pipe, according to circumstances. The products of combustion are
discharged through a pipe of small diameter, which may be readily
inserted into an already existing chimney or be hidden behind the
wainscoting. The heat furnished by the gas flame is so well absorbed by
radiation from the radiator rings that the gases, on making their exit,
have no longer a temperature of more than from 35 to 40 degrees.

[Illustration: SEE'S GAS STOVE.]

The apparatus, which is simple, compact, and cheap, is surrounded on all
sides with an ornamented sheet iron casing. Being entirely of cast iron,
it will last for a long time. The joints, being of asbestos, are
absolutely tight, so as to prevent the escape of bad odors. The water
due to the condensation of the gases is led through a small pipe out of
doors or into a vessel from whence it may evaporate anew, so as not to
change the hygrometric state of the air. The consumption of gas is very
small, it taking but 250 liters per hour to heat a room of 80 cubic
meters to a temperature of 18 deg. C.--_Revue Industrielle_.

The number of persons killed by wild animals and snakes in India last
year was 22,125, against 21,427 in the previous year, and of cattle,
46,707, against 44,669. Of the human beings destroyed, 2,606 were killed
