The varying color OF a vacuum tube
containing krypton, seen by some as IL
Iae and by others rs green. is explained
by Prof W. Ramsay to depend on The
size Of the yellow spot of The retina.
To illustrate immensely and minute
ness. J. L. Gore cites the fact that the
nearest fixed star Is 2T1,0O0 times as
far away as the sun. aud that speei-
men OF certain infusoria canlie between
tMo lines of an inch space divided into
twenty-five thousand parts.
Obesity Is regarded by DIR. Gabriel
Leyen. II French physician, as a ner-
yous disorder. 1t is not disease. hut
a symptom arising from various eondi-
lions. with some disturbance Of nutrl-

TO the dyspepsia.
1t Is difficult to account for the enor-
nous velocity Of some birds flight
when migrating. The northern blue
throat goes at the rate of $40 miles an
hour, flying 1880 miles from Egypt TO
Heligoland in a spring night of barely
nine hours. Nlrglnian plover fly from
Labrador to North Brazil. $500 miles.
without stopping going at the rate Of
636 miles an hour, and probably more.
How can this speed be attained? The
birds resort to great height, where the
resistance OF the air is light.
One of the puzzles Of geography has
been the question of the situation of
the sources and upper portions of the
three great rivers, Hoangho. Yangtze
and Mekong, all Of which start from
the lofty plateau of Tibet. Two of the
rivers traverse China, the Mekong
makes its way TO the sea between
Anam and Siam. This puzzle has been
partially cleared up by the explorations
of the Russian Captain Kozloff during
1900 and 1901. He found that the three
rivers flow on the surface of the great
plateau, 1900 feet above sea-level,
and are separated from one another by
parallel ranges of mountains rising
about 5000 feet above the plateau. and
running In a northwest and southeast
direction.
The fact that the sun when poised on
the horizon sometimes appears greatly
distorted, or drawn out into the form
of an oval, is well known, and the ex-
PLANTATION is very simple. namely. the
rapid change in the retroactive index of
the air near the horizon, In consequence
of which the lower edge of the sun ap-
pears to be lifted with reference to the
upper edge. and so the disk looks as II
squeezed between top and bottom. Re-
Gently Professor Prinz. OF the Brussels
Observatory, has obtained several large
scale photographs Of the setting sun
which distinctly show the reformation
Of the disk. and render its measure
ment very easy. In one case the vertl-
cal diameter Is to the horizontal in the
ratio of 10 TO 81 Sometimes the dlsior-
ton is greater than that.
Exeayatng by Compressed Alr.-In
sinking the Brooklyn caisson for the
third bridge over the East River. 1t has
been found possible to make compress
ed air do the work OF shovels In remoy-
ing the sand. through thick stratum
of which the calsson is being forced
down toward the bedrock deep be-
meath. The sand is so pure and loose
that the force OF the compressed air
supplied for the workmen In the Gals
son suftiees to drive II up through blow
mines inserted into fbo cafeaop for tbn
purpose. Jets OF water are directed
against the sand around the bottom of
the blowpipes. and when thus dis
lodged the sand readily passes up
through the pipes with the strong air
currents that are continually pouring
into them from the compressed atmos-
phere of the calsson.
