| DIR. MetZen baum classes radium with
the F'insen light, X-rays and surgery
in the treatment of lupus, and with
surgery and the X-rays in the treat
ment of rodent ulcer and small sur
face cancers. In these cases, healing
is rapid and apparently permanent,
while the beneficial effects OF radium
are obtained from tubes of low activ-
ity, costing but few dollars. Deep
seated malignant growths seem beyond
the influence of Iadium rays, and the
expected benefit in blindness has not
been realized, while Iadlum cannot
tske the place of X-rays for skiagraphs
on account of the length of exposure
necessary and the Irritation that
would result. Radium has some effect
in making ulcer scars smooth, pliabIe
and healthy in appearance.
The Crayeri method of preserving
meat lately found by Italian experts
to promise advantages over all other
processes, consists in draining the
veins of the slaughtered animals, and
then injecting solution of 100 parts
OF water, 25 of kitchen salt and of
acetic acid to the amount of one
tenth of the living weight. In the
Turin tests, treated sheep and calf
were hung for rs days in cellar at
81 degrees +. They were then Skim
ed, dressed and cut up, when the
desh was found fresh in appearance
with no trace of putrefaction, and
proved to be tender, unusually we'll
favored, dlgestible and nutritious.
From observations on Mont Blanc
and recent discoveries in physics, A.
Hausky has concluded that the solar
corona, zodiacaI light and aurora
borealis are all electrical phenomena,
and are due to negatively charged
PARTICLES detached from the sun and
repelIed by the pressure of light with
velocity of several thousand miles
second.
Our conception of the earth's inter-
ior is being gradually transformed by
the discoveries in radioactivity.
Radium or radioactive substance has
been found in all igneous rocks, but
is most in evidence in GRANTEES and
least so in basic rocks. That it is
the cause of the earth's internal heat
Is an idea that is gaining ground.
The distribution of radium is fairly
uniform, and this gives basis for
calculations showing that the ea1th's
crust cannot be much more than 45
miles deep, as otherwise the outflow
of heat would be greater than is OBJ
served, and for the conclusion that
the ior-comparativeIy cold in
stead of molten mass-must be of
some totally different material. The
last result agrees with that reached
| by Prof. Milne from the velocity OF
earthquake travel through the inter
ior. The moon probably consists
mostly of rock, with an internal tenn
| perature much greater than that of
the earth, and this explains the great
development of lunar volcanoes.
Iron meteorites contain little radium.
The flight of boomerangs is iIlu-
strated by L. Pfaunder, German
lecturer, by means of various shaped
little models, from to inches long.
These are cut from aluminium foil a
fftieth of an inch thick, and they are
hammered convex on one the concave
edge to the front, one end projecting
over the side of the table almost on a
level with the top of flat vertical
spring. The spring drives the boone
rangs forward and upward 6 or 8
yards, and then the bit of metal
returns and falls near it's starting
point.
Contaminated air is drawn from a
room through stove or tiue by rea-
son of the lower atmospheric pressure
10 detect when the ventilation is not
properly continuing, an Italian,
SIgnor Bertlni, has devisd an instru-
ment called the noseroscope, which
rings an alarm bell when the dimin-
ished pressure disappears. This gives
due notice that foul air must be
collecting in the room.
The highest dwelling place continu-
ously occupied, according to DR..
Leonard Hills new work on progress
in physiology, is the Ell Misti Obser-
vatory in the Andes, at 1920 feet.
The observatory of AIequipa is al
660 feet above sea-level. Thok-

Potosi, which has mum bered 100, 00(

Jourdanet says the Inhabitants of th
high attitudes in America are anaemi
' and of poor physique, and Mosso say
= the same of the shepherds of the higl
Alps. This is probably an effect o
poor food rather than of lessened al
pressure. 1t is said that no cats liv

Villages of the CordiIlera, become de
