ge-shaped enclosure, with a continuous but
somewhat irregular border. It is about 112 miles in extreme length, and
rather more than half this in breadth. The loftiest section of the wall
is on the W., where it rises 13,000 feet above a considerably depressed
interior. There is a bright crater on this side and some terraces. On the
broad inner slope of the E. border, the summit ridge of which is
especially well-marked, there is a large shallow depression. The floor
contains scarcely any detail, except some ridges on the N. side and a few
craterlets. The great bright plain E. of Schiller and the region on the
S.E. are especially worthy of scrutiny under a low morning sun.

BAYER.--This object, 29 miles in diameter, with a terraced border rising
on the W. to a height of 8000 feet above the floor, is so closely
associated with Schiller, that it may almost be regarded as forming part
of it. A long lofty mountain arm, apparently connected with the W. wall
of the latter, runs from the E. side of Bayer towards the N.W. There is a
crater on the E. side of the interior.

ROST.--An oblong-shaped ring-plain, 30 miles in diameter, on the S.W. of
Schiller, with moderately high walls, and, according to Neison, a shallow
depression within, nearly central. I have seen a crater shown by Schmidt
on the E. side of the floor. A valley runs from the E. side of Rost to
the S. of Schiller.

WEIGEL.--A not very conspicuous ring-plain on the S. of Schiller, with a
crater on its N.W. rim, and a larger ring adjoining it on the S.E. A
prominent curved mountain arm from the E. wall of Schiller runs towards
the N. side of this formation.

BLANCANUS.--A formation, 50 miles in diameter, on the S.E. side of
Clavius, whose surpassing beauties tend to render the less remarkable
features of this magnificent ring-plain and those of its neighbour
Scheiner less attractive than they otherwise would be. The crest of its
finely terraced wall, which at one peak on the E. rises to 18,000 feet,
is at least 12,000 feet above the interior. Krieger saw twenty craters on
the floor (1894, Sept. 21, 13h.), most of them situated on the S.
quarter.

SCHEINER.--A still larger object, being nearly 70 miles in diameter, with
a prominently terraced wall, fully as lofty as that of Blancanus. There
is a large crater, nearly central, two others on the N.E. side of the
floor, and a fourth at the inner foot of the E. wall. There is also a
shallow ring on the N.E. slope. Schmid
