Fireless or self-cooking stoves,
which have been SO popular in Ger
many for number of years, have
been recently much improved. The
early types we're simply boxes made
with double walls so BIS to retain the
heat, and food to be boiled or stewed
was first thoroughly heated and then
enclosed in the box for a sufficient
time to cook by the retained heat.
The latest apparatus is stated by
deputy consul general j. W. Dye of
Berlin, to be heated by stone.
This is made sufficiently hot in all
oven or over any fire, then placed
in the cooker with the steak or roast,
and the box is sealed up and left
for an hour or so until the food is
thoroughly cooked and hot. With
double boxes, boiling, frying and
roasting may all proceed at once
without care.
The difficult question of the in
fluence of environment on the height
of the human body has been taken
up by Pittard, karmin and Kappeyne
in the Swiss cantons, where a homo
geneous population lives under great
| ly varied conditions. Their results
all contradict previous beliefs, as
they find that the tallest men live at
the greatest altitude in Che noun
tains, also that height is greater in
regions less exposed to sunlight, and
greater on primitive or lgneous rock
than on limestone.
The "Vitascope' of English instru-
ment makers is novel telescope,
about foot long when closed, with
lenses arranged to magnify II dia
meters at distance of 20 inches and
60 dlameters at 5 inches. IT is de-

and other small living objects, at
suitable distance, and adds greatly
10 the nature Students power to
observe the minute life about us.
The curious perpetual motion de-
vice of M. Daune, Madame Cdries
assistant, embraces a glBss globe into
the upper part of which is fused a
small glass tube, closed at the bottom
and left open to the outer air at the
top. A brass tube, bearing leaf of
gold forming an eIectroscope, sur
rounds the lower part of the globe,
and is supported on an insulating
post of quartz upheld by brass rod.
On producing a Crookes vacuum in
the globe and inserting a bit of rad
ium in the little central tube, the
negative rays-ur Beta PARTICLES
readily pass through the thin glass.
Their charge is communicated to the
enveloping brass tube, causing the
ends of the gold leaf to diverge until
they touch platinum wire, which dis
charges the gold-leaf and the brass
tube. A new negative discharge,
however, Immediately begins to ac-
cumulate, repeating the process.
This continues Indefinitely, and the
gold Leaf is charged and discharged,
opening and closing, IN steady alter
nation by very small amount of
radium.
The problem of right handedness,
DR.. Geo. M. Gould concludes, as
solved by two military and social
facts: ID From the first use of imple
ments of offense and defense, the left
or heart side has been protected by
the shield and the left hand has been
called the shield hand; (2) and the
free or right hand was not only en-
ployed for the spear but for counting
in primitive barter, and other pur-
poses, becoming necessarily dominant
in all active operations. The pecu-
liarity seems to be entirely absent in
lower animals. Squirrels that hold
nuts in their fore paws, cats that
strike at insects or play with mcie,
and even monkeys and gorillas, give
no suggestion of preference for paw
or eye of either right or left side.
