To Barbicane and Nicholl the "Sea of Clouds" was an immense depression
of ground, with circular mountains scattered about on it; covering a
great part of the western side of the southern hemisphere, it covered
184,800 square leagues, and its centre was in south latitude 15 deg., and
west longitude 20 deg.. The Ocean of Tempests, _Oceanus Procellarum_, the
largest plain on the lunar disc, covered a surface of 328,300 square
leagues, its centre being in north latitude 10 deg., and east longitude 45 deg..
From its bosom emerge the admirable shining mountains of Kepler and
Aristarchus.

More to the north, and separated from the Sea of Clouds by high chains
of mountains, extends the Sea of Rains, _Mare Imbrium_, having its
central point in north latitude 35 deg. and east longitude 20 deg.; it is of a
nearly circular form, and covers a space of 193,000 leagues. Not far
distant the Sea of Humours, _Mare Humorum_, a little basin of 44,200
square leagues only, was situated in south latitude 25 deg., and east
longitude 40 deg.. Lastly, three gulfs lie on the coast of this
hemisphere--the Torrid Gulf, the Gulf of Dew, and the Gulf of Iris,
little plains inclosed by high chains of mountains.

The "Feminine" hemisphere, naturally more capricious, was distinguished
by smaller and more numerous seas. These were, towards the north, the
_Mare Frigoris_, in north latitude 55 deg. and longitude 0 deg., with 76,000
square leagues of surface, which joined the Lake of Death and Lake of
Dreams; the Sea of Serenity, _Mare Serenitatis_, by north latitude 25 deg.
and west longitude 20 deg., comprising a surface of 80,000 square leagues;
the Sea of Crises, _Mare Crisium_, round and very compact, in north
latitude 17 deg. and west longitude 55 deg., a surface of 40,000 square leagues,
a veritable Caspian buried in a girdle of mountains. Then on the
equator, in north latitude 5 deg. and west longitude 25 deg., appeared the Sea
of Tranquillity, _Mare Tranquillitatis_, occupying 121,509 square
leagues of surface; this sea communicated on the south with the Sea of
Nectar, _Mare Nectaris_, an extent of 28,800 square leagues, in south
latitude 15 deg. and west longitude 35 deg., and on the east with the Sea of
Fecundity, _Mare Fecunditatis_, the vastest in this hemisphere,
occupying 219,300 square leagues, in south latitude 3 deg. and west
longitude 50 deg.. Lastly, quite to the north and quite to the south lie two
more s
