PLATE XIV. 



PART OF THE SHORE OF THE OCEANUS IMBRIUM. BY M. HENRY, PARIS OBSERVATORY. 



AGE OF MOON, 24O HOURS. 



In this plate there are a number of features discernible in the others, but here better exhibited 

 than elsewhere in this series of illustrations. The Oceanus (or mare) Imbrium occupies the cen- 

 tral part of the picture, its northern, western, and a part of its southern margin being shown. The 

 large vulcanoid with the dark floor on the northern coast is Plato. South of it, a little way out 

 upon the mare, is a group of noble peaks called the Teneriffe Mountains. The loftiest rises about 

 eight thousand feet above the mare. 



Following around the shores of the Oceanus Imbrium to the left hand, we note near Plato 

 the great group of the Alps where there are some hundred peaks, one rising twelve thousand feet 

 above the mare. Cutting across them the .\lpine valley is faintly shown. Farther to the left we 

 find the Caucasus, a ridge-shaped mountainous district, with one of its many peaks nineteen 

 thousand feet high. South of this (upwards on the plate) is the passage connecting the Oceanus 

 Imbrium with the Mare Sereniiatis. On the left hand from this strait the first white spot is Linne 

 (see p. 70). On the right of the strait are two craters, the lower Aristillus, the upper Autolycus. 

 Farther up to the right is Archimedes. It is about fifty miles in diameter. Above the last-named 

 structure is an unnamed mountainous district. The lower parts of these fields appear to have been 

 swept over by the lava of the mare, but the higher are unaffected by it. The shore to the left of 

 this field from the strait southward is termed the Apennines. The fine crater near the end of 

 their distinct line is Eratosthenes. Farther on, out in the dark field of the Oceanus Procellarum, is 

 the great vulcanoid Copernicus. Just below it, faintly shown, is a group of elevations termed the 

 Carpathian Mountains.
