bicycling has conquered the French
Academic des Sciences. 1t announces
as the subject for the Fourneyron
mathematical prize for 1897: THE
Theory Of Motion and More Particu-
larly the Conditions of Stability of
Velocipedic Apparatus (bicycles, safe
ties, ETC. }, in Rectilinear and Curvilinear
Motion on Horizontal and Inclined

From the Swiss meteorological rec
ords since 1888 DIR. G.. Heiss finds that
hail Is more frequent in valleys than
on mountains, that it occurs oftener
near marshes and in lake valleys than
over wooded country, and that river
valleys in the path of thunderstorms
favor its formation, while cultivated
land and billy forest reduce the inten-
sity of hailstorms-
The Russian government has asked
permission of Turkey to make measure
ments of the sea of Marmora In order
to determine scientifically what
changes have occurred through the
late earthquakes. The porte has given
the desired permission, but the Russian
man-of-war WILDE escorted by Turk
ish vessel, and Turkish naval officer
will assist at all the scientific examina'
lions of the coast.
A cubic foot of air at the tempera'
ture of zero (Fahrenheit) can contain
only O.5 of grain of water vapor; at
80 degrees it can hold 2.13 grains; at 65
degrees it can contain 6.s grains. and
at 9s It can hold 1896 grains of mois-
ture in suspension. These figures &C
TO show that summer air can hold at
least nine times the quantity OF damp
ness that air can when reduced to the
temperature of freezing.
AT Augmagsalik, on the east coast
of Greenland, in latitude IS degrees 81
minutes north, a meteorological sta
ton has Just been established by the
Danish government. 1t is provided
with self-recording instruments as well
as the usual ones. Holm, who spent
year there ten years ago, found the
mean temperature for the year to be
degrees Fahrenheit below the freezing
point, while the minimum was ID de-
grees below zero.
The anthracite coal trade really
had no existence worthy of the name
until as late as 1920. Its actual be-
ginning, however, was in 1907, when
one Abigail Smith ran an ark loaded
with coal to Columbia from Wilkes
barre, and he continued to run several
arls yearly until 1926 In 1911 and 1912
some of the coal found its way to New
York by way of Havre de Grace. Until
1920 the entire shipment from the Wy
oming valley, the largest anthracite
basin in the world, in any year never
exceeded one thousand tons.
-Trional has been tested with sue
cess in long-continued cases of insom-
MIA by DIR. Rychlinslxi, who tells Of the
results in the Neurologisches Central
blatt. He administered doses OF from
half to one gramme, and in two cases
four grammes, and found that it pro-
duced unbroken sleep, without any
headache and with no evidence of bad
effect on the heart. The Lancet, while
admitting that further experience OF
the drug is necessary, thinks that the
experiments suggest that in the trional
we may find safe, efficient and relia

-Stras burger, a noted authority or
matters connected with vegetable bi
olgy, has recently attempted to show
that Transportation is accountable fol
the size and thickness of the leaves O.
plants. He illustrates his point by the
beech tree of the old world, which h
calls the red beech. Trees or branches
of trees in the shade of forest III
finds have thinner and larger leave
than those growing on the tops OF tn
trees or on branches that anywher
may be able to expose the foliage t.
the full sunlight. From this he deduce
n general law that the more sunligh
and the drier the atmosphere tn
thicker and smaller the leaves will be
Mr.. Flinders Petrie has come acros
