curcumin, auramine and a certain
amount of anethol, and writing paper
free from wood pulp-waS passed
through a strained glass picture or
colored positive. The anethol was
then removed from the print by soak
ing an hour or two in benzine. No
perfect fixing agent has been discov-
cred, but placing the print in a satu-
rated solution of su1phate of copper for
two or three hours, gave fair results.
The novel theory that volcanic erup-
tons produce glacial epochs Is ad-
vocated by Paul and Fritz Sarasin,
that a lowering of the mean annual
temperature by degrees or 8 de-
grees F. would be sufficient to give all
the phenomena of glaciation, and the
vast quantity of dust thrown off by
the Krakatoa eruption of 1884, and re-
naming suspended in the air for years,
satisfies these theorists that the sim
ultaneous eruption of many vocanoes
could so veil the sun as to give the
necessary slight lessening Of temper

new ice age at any time.
Simple eye strain is at the root of
many of the ills of nervous patients,

Spectroscopfc observations prove

quentIy than has been supposed. At
a new observatory near Gottingen. the
auroral line was distinctly seen in the
northern sky by E. Wiechert from Nov.
! 70 ., ana he was led at first to sus-
pect that the phenomenon is always
with US. But it could not be detected
on clear evenings of December and
January. The line again appeared in
an parts of the sky on Feb. S8 and
March 8, and it was calculated that if
the auroras height was not less than
thlrty miles, the same method should
qetect It as far as the south Of Italy.
In all these observations the naked
eye showed nothing but faint general
luminosity of the sky, not half az
bright as the Milky Way

contact on the Adams apple, the move

sary TO repeSt the motion 12O or 13O
times. The position of the contact Is
altered for obtaining pictures of other
phases of the swallowing. Despite tha
difficulties of this curious exnerinoant
fairly good photographs have been
made, and they throw new light on the
working of the organs of the throat
A familiar belief is that moss grows
chiefly on the north side@of trees. The
notion is not established by science.
and an examination of many trees has
shown Prof. Henry Kraemer, a Phila-
aelpnia botanist, that 10 per cent had
the moss on the west side, 10 per cent
on the northwest side. 10 per cent on
the north side, 20 per cent on the
northeast side. IS per cent on the east
side, and IL per cent on the southeast
