Fram Drawings by Professor Weinek, enlarged ten times from negatives made at the Lick Observatory
in August, I888.
JMfoon Photographs are regularly taken
with the great telescope, and it is the
intent to continue till a complete set
has been obtained for every hour or so
of the moon's age. Changes on the
moon's surface can thus be detected.
These photographs have been mechanically enlarged on glass by Professors
Burnham and Barnard, and they are
now sent regularly to Prague, to Professor Weinek, who makes enlarged
drawings of parts of the surface, which
are printed in heliogravure, at the expense of Walter Law, of New York.
These drawings are studied by Professor Weinek and Professor Holden with
great care, and Professor Weinek has
discovered many new features in this
way. Doctor Otto Boedicker, astronomer of Lord Rosse's observatory, Doctor
Ebert of Erlangen, and Doctor Franz of
Koenigsberg, are also making special
studies of them.
Milky Way. The Milky Way also is
to be studied by means of photographs,
which Professor Barnard is now taking,
attention having been directed to the
promise of excellent results through
some most successful ones that he had
made. The comet lately discovered
made its impression on one of these
plates, and was thus first recognized as
a stranger.
3pectroscopy.- Professor Keeler made
some remarkable spectroscopic observations, by which he established (for
the first time) the motions of nebulae in
the line of sight. \Vhen Professor
Campbell succeeded to the work, he
adapted the spectroscope intended for
visual observations to photographing
spectra, and the results showed enormous advantages in this method. To
this is largely due the unrivaled success
of the Lick Observatory in studying
the new star in Auriga. The greatest number of lines in its spectrum
reported from other observations is
three; Professor Campbell has measured fourteen. During the time this
star was very faint, the photographic
observations of the Lick Observatory
were the only ones by which it could be
followed. They alone showed its neb
