number of long spurs running out from the wall on the
N. towards the centre of the floor. Murchison A is named CHLADNI by
Lohrmann.

PALLAS.--A fine ring-plain, about 32 miles in diameter, forming with
Murchison an especially beautiful telescopic object under suitable
illumination. Its brilliant border, broken by gaps on the W., where it
abuts on Murchison, has a bright crater on the N.E., from which,
following the curvature of the wall, and just below its crest, runs a
valley in an easterly direction. There is a large bright central mountain
on the floor, with a smaller elevation to the S. of it, and a ridge
extending from the N. wall to near the centre. On the W., a section of
the border is continued in a N. direction far beyond the limits of the
formation; and on the S. it is connected with a small incomplete ring; on
the E. of which, near the foot of the wall, is a somewhat smaller and
much duskier enclosure.

BODE.--A brilliant ring-plain, 9 miles in diameter, situated on the N.
side of Pallas. Its walls rise about 5000 feet above the interior, which
is considerably depressed, and includes, according to Schmidt and Webb, a
mountain or ridge. There are two parallel valleys on the W., which are
well worth examination.

SOMMERING.--An incomplete ring-plain, 17 miles in diameter, situated on
the lunar equator. It has rather low broken walls and a dark interior.

SCHROTER.--A somewhat larger formation, with a border wanting on the S.
Schmidt draws a considerable crater on the S.W. side of the floor. It was
in the region north of this object, which abounds in little hills and low
ridges, that in the year 1822 Gruithuisen discovered a very remarkable
formation consisting of a number of parallel rows of hills branching out
(like the veins of a leaf from the midrib) from a central valley at an
angle of 45 deg., represented by a depression between two long ridges
running from north to south. The regularly arranged hollows between the
hills and the longitudinal valley suggested to his fertile imagination
that he had at last found a veritable city in the moon--possibly the
metropolis of Kepler's _Subvolvani_, who were supposed to dwell on that
hemisphere of our satellite which faces the earth. At any rate, he was
firmly convinced that it was the work of intelligent beings, and not due
to natural causes. This curious arrangement of ridges and furrows, which,
according to Webb, measures about 23 miles both in length and brea
