next morning I started northward for Auletta (20th February). In the hard gray morning light, the peakedness of the limestone mountains, of the high ranges, and the end-on-edness of the beds, are very striking. Passing Diano (in reverse direction) I remark, that the low spur that connects it with the hills behind, seems to be chiefly loose material, so that no push of the wave from the north could be transmitted through it, without immense loss and retardation. Passing La Sala again, I got a good observation of the sun, at a point about 100 feet above the great plain.

The observation was made at 1h 23′ 47″ by chronometer, Greenwich time.
