The continual trickling through gavethe surface a convex form and in themiddle is a numher of attempted out-rushings,suppressed by the cooling. Since the dis-covery of the deluge, it is clear to me, howin the plain of the Piccolomini the flow ofthe magma flooded the mound in a north-westerly direction, as is shown in this picturever}^ clearh\ Fig. 12. Al)ove is the Clavius, fullof ruins, below the new formation of theTyclio. In the whole South of the moonthere is no large object spared b}^ the here visil)le (not ruin-like formations) wereformed after the deluge and are of insig-niflcant size. Although at the Clavius thecurrents show clearly, the principal effectof the destruction lays in the melting inconsequenc
