The main physical features of the visible half of the moon, with a good telescopic power, present an enormously elevated table land, traversed, here and there, with slightly elevated long ridges, and the general surface largely pitted with almost innumerable deep cusps or valleys, of every size, from a quarter of a mile to full thirty miles in diameter; generally circular and surrounded with elevated ridges, some rising to lofty jagged summits above the surrounding plain. These ridges, on their inner sides, show separate terraces and mural precipices, while their outer slopes display deeply scarred ravines and long spurs at their bases. These cusps, or deep valleys, are the craters of extinct volcanoes, and in their centres have generally one or two isolated sub-mountain peaks, occasionally with divided summits, which were the centres of expiring volcanic action, similar to those that exist in our own volcanic regions. Besides which the Lunar Apennines, so called, present to the eye a long range of mountains with serrated summits, on one side gradually sloped, with terraces, spurs, and ravines, and the other side mostly precipitous, casting long shadows, which clearly define the forms of their summits--all these objects presenting the same dead white everywhere. Doubtless the farther side of the moon, which has not been subject to the same elongating or elevating process, nor the above-named causes for volcanic disruption, presents a climate and vegetation fitted for the abode of sentient beings. This side alone presenting an aspect of extreme desolation, far surpassing our polar regions. It is generally stated in astronomical works, that shadows projected from lunar objects are intensely black, owing, it is stated, to there being no reflecting atmosphere; whereas in my long-continued habit of observation, those shadows appear no more black than those on our earth, when they fall on contrasting snowy surfaces. The reason for which, in the absence of a lunar atmosphere, to render light diffusive, is the brilliant reflection from snow crystals, upon all contiguous objects, which lie in an angle to receive the same, and in consequence I have often observed the forms of objects not directly illuminated by the sun. The occasional apparent retention of a star on the limb of the moon, just before or after an occultation, seen by some observers, and thus evidencing the existence of some atmosphere, is doubtless due to the slight oscillations of the moon, by which we see a trifle more than half of that body, during which the atmosphere of its opposite side slightly impinges upon this.
