by gaps. There is a fine deep crater on the S. border, and a small
but distinct crater on the floor, nearly central, the only object thereon
which I have seen, though Schmidt draws a smaller one on the W. of it.

A mountain abutting on the N.E. side of Hesiodus is the W. origin of one
of the longest clefts on the moon. Running in an E.S.E. direction, it
traverses the Mare to a crater near the W. face of the Cichus mountain
arm, reappears on the E. side of this object, and is finally lost amid
the hills on the N. of Capuanus. The W. section of this cleft is coarser
and much more distinct than that lying E. of the mountain arm.

GAURICUS.--A large walled-plain S. of Pitatus, about 40 miles in
diameter. The border is very irregular, and, according to Neison,
consists on the E. of a precipitous cliff more than 9000 feet high. It is
surrounded by a number of large rings on the S., and has several
considerable small depressions on its N. border. There is apparently no
prominent detail on the floor. Schmidt shows some ridges and craterlets.

WURZELBAUER.--Another irregular walled-plain, about 50 miles in diameter,
on the S.E. of Pitatus, with a very complex border, in connection with
which, on the S.W., is a group of fine depressions, and on the S.E. a
large crater. There is much detail on the very uneven floor.

MILLER.--One of a group of three moderately large ring-plains, of which
Nasireddin is a member, near the central meridian in S. latitude 39 deg.
Its massive border rises nearly 11,000 feet above the floor, on which
stands a central peak. Miller is about 36 miles in diameter.

NASIREDDIN.--A somewhat smaller ring-plain on the S. of the last, and of
a very similar type. It contains a central peak and several minor
elevations. Between its N.W. border and the S.W. flank of Miller is a
smaller ring-plain of about half the size of Nasireddin, and on the S.E.
a large enclosure named HUGGINS.

ORONTIUS.--Huggins has encroached on the W. side of this irregular ring-
plain and overlaps it. It is of considerable size. The floor includes
much detail and a prominent crater.

SASSERIDES.--A formation of irregular shape, with very lofty walls,
situated amid the confusion of ring-plains, craters, crater-pits, &c., in
the region N. of Tycho, some of which are fully as deserving of a
distinct name.

HEINSIUS.--A very curious formation on the N.E. of Tycho: a fine
telescopic object under oblique illumination. It has an irregular
