Renewed speculation as to the cause OF the
mysterious force known as magnetism has
naturally followed DIR. Huesler's production OF
magnetic alloys from nen-magnetic materials.
One of his alloys-containing 60 per cent. Of
copper 20 Of manganese and IA Of aluminium
proved practically as magnetic as iron. but 1t Is
very brittle, and cannot be drawn or forged. On
attempting to increase the maIleability By add
ing iron. ali magnetic properties astOnishingly
disappeared. An old idea was that magnetism
is due to some popularity Of the iron atom, al
though this metal is not magnetic when heated,
but it now appears that magnetic properties
now depend upon some special grouping OF tue
atoms within the molecule.

All recorded submarine earthquakes have been
plotted on q map Of the world by wilhelm Krebs.
Many Of them represent submarine volcanic
erupticns and a very striking fact is their great
concentration in the narrowest part of the At
fsntic Ocean, between Africa and South
America. It is suggested that this greater ap-
parent activity may be due largely to lack OF
observations in the much less Travelled Pacific.
Other centers are the West Indies, the west
coast of South America. the south Of the Bay OF
Bengal. the Malay Archipelago, eastern japan,
and the Mediterranean.

Remarkable fireproofnR properties are credit
ed to oxide of titarium by an English dyer.
FIannelette treated with 1t could not be made
to urstinto flame, and other textiles are claimed
to be made equally resistant, while it cannot be
removed by dyeing. boiling or washing.

For fifteen years Joseph Oshausen, Euro
pean engineer, has been studying the speeds OF
many kinds of animals. Man reaches remark
able veIocIties but only by artificial aids. good
pedestrians rate being sixteenth Of mile in
IL seconds, while German soldier marches
three miles an hour. and five miles in quickstep.
The greatest speed of an athlete thus far noted
is the initial velocity of 303 inches second of
broad jumper. The average swimmers rate is
80 inches second, the oarsman's In an eight
cared barge is 1917 inches and the skaters Is nine
to ten yards, while the runner on skids has
made "A yards second and the jumper on skids
has reached almost 40 yards. The record on
bic,cle is 08 yards a second. The horse makes
long gallops at six miles an hour the fastest dog
the Russian wolf-hound-shows 70 feet a
second, and the gazelle attains 80 feet second.
Aided by its wings, the ostrich is the fastest
runner. sometimes making 96 feet second. In
measured flights, the Virginia rainpiper has
record of 1900 yards minute, and the European
swallow has exceeded 5000 yards. The slowest
creatures are snails and certain small beetles.

The improved and very sensitive automatic
fire alarm Of Danish inventor acts only when
sudden wave of heat is generated. U. tube
four inches high is half filed with mercury, the
upper parts containing sulphuric ether. and
both ends being closed. One side of the tube Is
covered with non-conducting material. An even

ether under the unprotected glass, forcing down
the mercury, and ringing an electric bell.

A new Scottish work attempts to prOve-from
geological phenomena-that gravitation is cleo
trica and that 1t is identical with terrestrial and
solar magnetism.
The altar or essential oil was extracted from
roses as far back as the time of Diosc0rides. but
the early process consisted in macerating rose
leaves in pure olive oil. The present distilla-
ton process, states a recent French writer, was
used before the eighth century. The damask
rose is the only kind used by most Bulgarian
distIllors. and these are pucked at dawn. just as
, buds begin to expand Each of the copper stills
is charged with % pounds of roses and 10 quarts
of water. After an hour and half about IL
quarts of rose is distilled and this to
obtain the OIL which is of deep straw color.
Adulteration with the cheaper oils of sandal
wood. geranium, etc.. is very common. Anacre

years Bulgarian product reached 18.77O pounds,
lowering the price to $50 pound or half the
usual value.
In European races Huxley recognized two male
stocks-the fair and dark Caucasian. Dr.Deniker
believes there are six well-marked races, viz i:
Cd The blonde, wavy- haired. long headed. long
faced and tall Northern Race: (2) the Eastern
race, also blonde, with straight hair, rather
short head, broad face, and short in stature; G)
the Ibero-insular Race, of Spain and Portugal.
which is dark, very short, long-headed. with
straight or retrousse noses and sometimes curly
hair; (l) the Western Race, dark, round-headed
and short. with round face, broad nose. and

Coast Race, very dark, long-headed, fairly tall
