om N. to S.; so it may be taken to include an area
on the lunar globe which is, roughly speaking, equal to half the
superficies of Ireland. This vast space, bounded by one of the loftiest,
most massive, and prominently-terraced ramparts, includes ring-plains,
craters, crater-rows, and valleys,--in short, almost every type of lunar
formation. It towers on the E. to a height of nearly 14,000 feet above
the interior, and on the W., according to Schmidt, to a still greater
altitude. A fine rill-valley curves round the outer slope of the W. wall,
just below its crest, which is an easy object in a 8 1/2 inch reflector
when the opposite border is on the morning terminator, and could
doubtless be seen in a smaller instrument; and there is an especially
brilliant crater on the S. border, which is not visible till a somewhat
later stage of sunrise. The central mountain is of great altitude, its
loftiest peaks standing out amid the shadow long before a ray of sunlight
has reached the lower slopes of the walls. It is associated with a number
of smaller elevations. I have seen three considerable craters and several
smaller ones in the interior.

BAROCIUS.--A massive formation, about 50 miles in diameter, on the S.W.
side of Maurolycus, whose border it overlaps and considerably deforms.
Its wall rises on the E. to a height of 12,000 feet above the floor, and
is broken on the N.W. by two great ring-plains. On the inner slope of the
S.E. border is a curious oblong enclosure. There is nothing remarkable in
the interior. On the dusky grey plain W. of Maurolycus and Barocius there
is a number of little formations, many of them being of a very abnormal
shape, which are well worthy of examination. I have seen two short
unrecorded clefts in connection with these objects.

STOFLER.--A grand object, very similar in size and general character to
Maurolycus, its neighbour on the W. To view it and its surroundings at
the most striking phase, it should be observed when the morning
terminator lies a little E. of the W. wall. At this time the jagged,
clean-cut, shadows of the peaks on Faraday and the W. border, the fine
terraces, depressions, and other features on the illuminated section of
the gigantic rampart, and the smooth bluish-grey floor, combine to make a
most beautiful telescopic picture. At a peak on the N.E., the wall
attains a height of nearly 12,000 feet, but sinks to a little more than a
third of this height on the E. It is apparently
