What is termed the infinite variety
in the world of organic beings that we
can see, bears no comparison to the
immense variety in the invisible world
which only the microscope can show u.s.
The scientific serials and publications
devoted to classification are full to over
flowing of new species continually being
discovered and described. In the last
issue of the Proceedings of the Phila-
delphia Academy, Messrs. Ellis and
Everhardt describe ninety-nine new
species of microscopic plants.
Prof. Joseph Leidy, of Philadelphia,

the deduction of anatomists that quality

"A means of taking a panoramic
photograph of long stretch of country
in fact all around the horizon - has
been devised by NJ. Damoiseau, a French
| inventor. 1t consists of a camera,
which is pivoted on horizontal plate
supported on three legs, after the man
ner of theodolite. The camera slowly
moves round on its pivot, while at the
| same time the sensitised paper moves so
as to present a fresh surface to the
image, and the adjustment is so perfect
that the photograph is quite distinct in
every part.
| The boring of artesian wells along
/ the coast of New Jersey has afforded a
new field to the archaeological geolo-
I gist. The result of an examination Of
numerous wells in the southeastern
| portion of the state leads Mr. Woolman,
of the Philadelphia academy, to the
conclusion that there is a greater thick
ness of the Miocene deposits in the
southern parts of the state than has
been generally held by geologists, and
as consequence, increases the hereto
fore estimated dip of the underlying
Cretaceous and Eocene beds in that Sec
ton of the state of New Jersey.-N. Y.

The deepest hole in the world is at
Wheeling, w. Va, where an eight-iuch
well has been sunk nearly mile When
it has reached that depth the govern
ment will take up the work under the
direction of two expert officers of the
geological survey and drill into the
earth as far as human skill can pene-
trate. The idea is to take the tempera-
ture and magnetic conditions as far as
possible and by means of an instrument
constructed for the purpose, a complete
record OF the progress and all discov-
cries made will be kept and placed in
the Geological Survey exhibit at the
worlds fair.
Most people are probably not aware

which is also sun, is believed to have
nearly five thousand times the volume
of our sun. Its immense distance. prob
ably hundred million millions of miles,
makes such measurement as is applied
to the planets impossible. Hence the
above estimate is based on a compari-
son of the light of Sirius with that re-
ceived from the sun. 1t is the most
brilliant star in the heavens, being far
brighter than the first magnitude, and
its light has greenish tinge. During
the winter months the place to look for
Sirius is in the southern heavens.

Years ago it was supposed that
Sirius was nearer the earth than any
other star, and its light requires over
three years to reach us. Now, how
ever, Alpha Centauri, comparatively
insignificant star of the southern heav-
ems, is known to be our nearest neigh
Dor, and Sirius is so far removed that
the human mind fails to grasp the dis
tance when expressed in miles The
fact that light requires from seventeen
to twenty years to cross the space be-
tween our little earth and this giant orb
is scarcely more easy to comprehend.
If one would appreciate the magnifi-
cence of this most brilliant of suns he
should not think of it as near but
rather let his mind make the vain at
tempt to follow ray Of light thither,
as it travels on, unwearied, day and
night, at the rate of $4,000 miles a sec
