The MooS-An interesting paper on the appear.
ances Of the surface Of the Moon read before the
Convention of Geologists and Naiuralists, now IN
session at New York. Thursday last, by the author.
JAMES D. DANA, Esq. The following from the Tr-
bune gives the substance of it:
The surface Of the Moon has been infinitely studied
in physical point Of view, and already many inter
esting geological discoveries have been made. loJ3
lunar lights have been measured by Beer and Nader.
Drawings of several Of these mountains were ex-
hibited BY Dr. Dana One important subject in
regard 10 the Moon,ye remains unexplaned--viz.:
the immense magnitude Of its oraters. One Of them
has been asceraned to be $50 300 miles in diam
eter and % goo feet deep. The crater Bailey is l49t
statute miles In diameter. 1t stated IN the report
that two-thrds of all the lunar hemisphere in view
composing its Southern quarter-are covered with
volcanic mountains. The names, heights depths and
pecuariies of the various craterS aud mountains OF
the Moon particularized in the paper Of Mr.
Dana and numerous drawings-plans of these eleva-
tions and the inside Of their craters-were shown
The walls of the craters frequently regular
TO appear almost artificial. One very singular cir
cumsance observable in them is that the sides appear
more Illuminated, more brilliant. than the bottoms.
May this be accounted for by the existence of
nebulous light, apparently in the lower portion

the speaker If not viii he please TO correct US y
The absence of water in the Moon, and the princ
pal volcanoes elsewhere observed, then treated
Of; after which were taken up the subjects Of the
+
of land and water on our globe, as compared with
the Moon. In the ocean, all the islands, except the
! corals, are Of an igneous formation.
! When Mr.. Dana closed, Prof SILLIMAN inquired
how Mr.. Dana would account for the volcanic action
of the Moon without the agency Of water TO produce
the vspors always accompanying a volcano ! To
which Mr.. Dana replied that it not absolutely
decided that there IS no water in the Moon, but that
mona had yet been perceived. Before he had time 10
answer Prof. SrLLINANs special interrogation, the
President, DR.. JACKSON, remarked that the presence
of chlorine in the Moon was not mproba be-as this
substance had been found in the meteoric stones
and might not this be the cause of vapors of lunar
volcanoes! Sulphur has also been found meieortes.
WONDERFUL lNvENTIoNs.-A correspondent Of the
