Wollaston.  An isolated triangular mountain about midway between this and Wollaston B.

THIRD QUADRANT.

The Riphaean Mountains.  An isolated range S. of Landsberg in S. lat. 7 deg., E. long. 28 deg.  They run in a meridional direction, and rise at one peak to nearly 3000 feet above the Oceanus Procellarum.

The Percy Mountains extend from the eastern flank of Gassendi towards Mersenius, forming the north-eastern border of the Mare Humorum.

Prom.  Aenarium.  A steep bluff situated at the northern end of a plateau, some distance E. of Arzachel, in S. lat. 18 deg., E. long. 9 deg.  It rises some 2000 feet above the Mare Nubium.

Euclides zeta and chi.  Two mountain masses N. of this formation in S. lat. 5 deg.; zeta rises about 1700 feet above the Mare; both are evidently offshoots from the Riphaean range.

Landsberg H. An isolated hill in S. lat. 4 deg., E. long. 25 deg.

Nicollet C. S.E. of Nicollet, in S. lat. 22 deg., E. long. 17 deg.; is hemmed in by a mountain mass rising to more than 2000 feet above the Mare Nubium.

The Stag’s-Horn Mountains.  At the S. end of the straight wall, or “railroad,” in S. lat. 24 deg., E. long. 8 deg., a curious mountain mass rising about 2000 feet above the Mare Nubium.

Lacroix delta.  A mountain more than 7000 feet high, N. of Lacroix.

Flamsteed E. A mountain of more than 3000 feet in S. lat. 4 deg., E. long. 51 deg.

D’Alembert Mountains.  A very lofty range on the E. limb, extending to S. lat. 11 deg.

The Cordilleras.  Close to the E. limb; they lie between S. lat. 8 deg. and S. lat. 23 deg.

Rook Mountains.  On the E. limb, extending from about S. lat. 18 deg. to S. lat. 35 deg.  According to Schroter, they attain a height of 25,000 feet.

Dorfel Mountains.  On the S.E. limb between S. lat. 57 deg. and S. lat. 80 deg.

Leibnitz Mountains.  On the S. limb extending W. from S. lat. 80 deg. beyond the Pole on to the Fourth Quadrant.  Perhaps the loftiest range on the limb.  Madler’s measures give more than 27,000 feet as the height of one peak, and there are several others nearly as high.

FOURTH QUADRANT.

The Altai Mountains.  A fine conspicuous serpentine range, extending from the E. side of Piccolomini in a north-easterly direction to the region between Tacitus and Catherina, a length of about 275 miles.  The loftiest peak is over 13,000 feet.  The average height of the southern portion is about 6000 feet.  The region lying on the S.E. of this range is a vast tableland, devoid of prominent objects, rising gradually towards the mountains, which shelve rapidly down to an equally barren expanse on the N.W.

The Pyrenees.  These mountains, on the E. of Guttemberg, border the western side of the Mare Nectaris.  Their loftiest peak, rising nearly to 12,000 feet, is on the S.E. of Guttemberg.
