chain of mountains, connecting “ Babbage ” with Anaximander, forms the eastern 
boundary of the table-land. Beer and Midler have leftits boundaries undetermined, 
and further observations are necessary to mark them out with precision. 
Eye-sketch of a chain of Lunar craters, with three large unnamed and unrepresented craters, 
taken at Hartwell on the morning of Sept. 18, 1862. 
I. Philolaus (Riccioli). A ringed mountain. 
If. Anaximenes (Riccioli). A ringed mountain. 
Til. An unnamed crater on Beer and Midler’s map. It is marked “ Sommering”’ 
by Le Couturier. Beer and Midler have another “Sommering” near the centre of 
the disk. 
IV. Anaximander (Riccioli). The ring of this crater is imperfect, and requires 
further observation to define its outline accurately. Between it and V there is a 
well-marked mountain, besides other interesting features. 
V. Herschel I. (Birt). An extensive depression of the character of a walled 
plain, with a nearly perfect ring not shown by Beer and Madler, who describe the 
region between Horrebow, Anaximander, and Fontenelle as an exceedingly rich 
crater country ; the principal part consisting of the region of Herschel II. 
The following features are common to the eye-sketch and Map :— 
B. A high mountain mass marked Anaximander B by Beer and Madler. It 
really forms the north angle of the wall of the large depression Herschel I. 
e. A mountain mass forming the N.W. angle of the ring of Herschel I. 
f. A crater exterior to Herschel IT. 
c,d. Two craters in the line of eruption that crosses Herschel II. in a curvi- 
linear direction. 
The eye-sketch shows the general direction of this eruptive line from the portion 
of the ring that is absent to a crater east of Horrebow(X). It is not shown on the 
German map. 
VI. The table-land “ Robinson ” (Birt). 
A, B, and C. Craters on the table-land. 
E. A steep mountain “steppe” on the south, not shown in the sketch, 
dipping to the depression “South.” It contains the three dark mountains of 
Beer and Midler. 
F. A steep mountain “steppe” on the north, dipping to Herschel I. 
E and F were observed and figured by Schroter in his ‘Selenotopographische 
Fragmente,’ T. xxvi. fig. 1. 
VII. A depression south of the table-land “ Robinson.” Proposed name “ South ” 
irt). The central crater D is shown by Beer and Madler. 
VII. Another depression eastward of “South,” and between it and Pythagoras. 
The crater A on Beer and Médler’s map is really nearer the west border than shown 
in the eye-sketch. Proposed name “ Babbage” (Birt). 
Schroter observed this walled plain. Figures of it, with the interior crater A 
close to the western edge, are given in T, xxvi. (figs. 1 and 2) of his ‘Selenotopo- 
graphische Fragmente.’ It would appear that he designated it “ Pythagoras,” the 
crater now bearing that name being termed Pythagoras borealis, By far the most 
suitable name for the large crater with the central mountain is that on the large
