Abstract
DR. LUCERNA has made an elaborate study of the physiography of the mountains which occupy so large a part of Corsica, and culminate about 2700 m. above sea-level. Brought up, evidently, at the feet of Prof. Brückner, he has no difficulty in recognising the pre-glacial valley floors and the successive deepenings due to the advancing glaciers of the Giinz, Mindel, Riss, and Wiirm times. The existing moraines, of course, chiefly belong to the last of these, and he is able to identify, as has been done in the Alps, the Buhl, Gschnitz and Daun stages of retreat. The height of the snow-line appears to have varied with the locality, but was generally rather lower than in the southern parts of the Maritime Alps; in more than one place it was about 1650 m., which would signify a sea-level temperature nearly 17° F. lower than that of Ajaccio at the present day. In the valleys, terminal moraines occur, these, of course, being at various levels; for example, in one case at 1350 m., in another as low as 750 m.
