SCIENTIFIC MISCELLANY.
A record in steam economy is claim
ed for Parsons tubro-motor built for
an electric station at Elberfeld, Ger
many. The steam consumption on trial
was only 70 pounds per indicated horse
power per hour, which is probably
or ~ pounds less than the lowest con-
sumption of reclprocating engines.

that the disease is chiefly distributed

Osmium wires having been produced
by process invented by Auer Won
Welsbach, such wires have been tried in
incandescent lamps They are heated
BY the passage of the electric current,
like the ordinary carbon flament, and
as they stand high temperatures well,
osmlum being the most difficult OF all
metals to fuse. lighting Is erected
with great economy. The current IL
used at pressures OF only 20 70 30 volts,
Experiments have shown that for the
same candle-power the osmium lamps
use only 40 per cent Of the current Of
ordinary incandescent lamps OF the
same voltage; and that when an osmi-
um lamp and carbon fllament lamp
consume the same energy the former
gives 31s times the candle-power or the
latter. The life OF the Osmium lamp
may range from 700 to 1900 hours

tubing at distances OF one-half TO three
fourths OF an inch, the whole being laid
upon a suitable support covered by

water running through the tubing
maintains an even temperature OF any
reauired degree. In the mattress the
tubing Is so arranged that either the

forms a soft and comfortable couch'
Resides other applications, this offers a
very convenient method OF inducing

One of the problems now awaiting
solution Dr. Eneas Monroe points out
is the suppression OF plague that mas
wrought greater destruction than az

constantly going on somewhere Dur

great damage in the southern
REPUBLICS Of South America,
in North and South Africa
etc. countries widely separated. Inc
creatures are little known IN their per-
manent or true homes. The only sue

has come from taking advantage OF the
fact that the younger and weaker To-

II has been noticed that body sus-
pended above LIQUID air receives strong
negative identification. Ebert and
Hoffman find that this charge Is not
due to the LIQUID air itself, but to the
action of minute particles Of very
cold ice suspended in IT, This may ac-
count for the electric effects OF polar
snowstroms.
Vegetorians are rare among fish, says
an English naturalist, the tench and
gray mullet being perhaps the only
British species with such tastes. The
carp Is mistakenly so called. a fayorite
food being frogs.
For a considerable time the convie-
ton has been growing that electric de-
yelopment is destined 20 check the flow
OF populatio to cities. OF extraordinary
interest In this connection Is the eXperI.
ment at Hollriegelsgerent a small Wi.
lage near Munich, where the WATERPROOF
er OF the river lsar Is being used TO
generate electric current for agricul-
tural and other small industries over
an extensive area. \ total Of 25 firms
and 30 premises OF various kinds. In
q villages and rural districts. are now
supplied light and power. Four tur-
bines yield 1000 horsepower, while

most significant feature OF the enter
