MAP OF THE MOON.

In connection with the cablegram published in Saturday's' issue regarding tho new map of tho moon, it may be pointed, out that thanks to the labours of a succession of abkr German astronomers—Tchias Mayer,. Schroter, Xohrmann, Madler, and Schmidt—we are now fully acquainted with the mountains and craters on the moon's surface. Thoro are many mountain ranges, but the most prevalent type of formation is undoubtedly the volcanic clator. Even tho smallest telcscope will levoal the larger of those craters, such as tho well-known formations called Plato, Tycho, and Copernicus. The late Mr. Elger, a well-known English observer of the moon, remarks:—"However familiar we may. be with -the lunar surface, .wo can never gaze on these extraordinary formations, whether massed together in inextricable confusion or standing in isolated grandeur on : tho -grey surface of the plains, without experiencing in a scarcely diminished degree the- same sensation of wonder, and admiration with which they were beheld for-the first time."

Th-sso crater formations are grouped into various classes, wliich Elger gives as walled plains, ;s;onntain rings, ringplain?, craters, cones, ci-atei-lets, craterpits., and depressions. Besides these there are tho curious features known as "rills," long furrows in the lunar surface; and there are also tho bright streaks which at the period of full moon radiate from' some of the larger craters, such as Tycho, Copernicus, and Kepler. No r:ally satisfactory explanation -of the causo of these streaks has yet teen advanced. Beer and Jtadler, two German astronomers who devoted ir.uch attention to our satellite, commenced in IS3O an exhaustive trigonometrical survey of the moon. -They ' published the results of their studies in a large -chart and a'descriptive vohin'-" en'.itled "Dsr Mond.." They 10 to tho conclusion that the moon was an ab-olutoly dead world, r.nd destitute of life of any kind, and this viewhas generally been adopted. It has b'en abundantly proved, too, that tho moon has no appreciable atmosphere; and the general idea among astronomers is that on such a world the existence of highly develoned forms of life is exceedingly im--probable.
