^{page 405 note 1} Most of these deposits are now obliterated, but ample specimens of the marine shells are preserved in the Geological Museum of Milan.

^{page 408 note 1} The principal localities of interglacial deposits between Lakes Maggiore, Lugano, and Garda, and beyond are the following: at Re, in the Vigezzo Valley, east of Domo d’Ossola; at Calprino, near Lugano; at Leffe and Gandino in the Seriana Valley, north of Bergamo; at Pianico in the Oglio (Lake Isco) Valley; at Valmarino in the Piave Valley, north of Treviso; in the Tagliamento Valley, north of Udine; and in the Isonzo Valley, north of Gorizia.

^{page 408 note 2} It is a striking feature that, of the moraine walls, those of the Como district are continuous, because the Adda eroded its bed marginally from the Lecco arm of the lake, whereas the rivers of Ivrea, Lake Maggiore, and Lake Garda (Dora Baltea, Ticino, and Mincio) found their exit more through the centre of the frontal moraines, which are therefore broken up into agglomerations of hillocks.

^{page 409 note 2} The deposition of the rich alluvia which cover the floor of the Po Valley, and to which it owes its wonderful fertility, began with the retreat of the glaciers when the rivers resumed their erosive energy, and continued throughout the long interglacial period after the maximum glaciation.
