The inferior subdivision of the Lower Molasse, called Aquitanian in Heer's work, is best seen on the northern coast of the Lake of Geneva. The beds consist of sandstone and conglomerate, and are nearly 2000 feet thick. The conglomerates are often very unequal in thickness, in closely adjoining districts, as might be expected, since in a littoral formation accumulations of pebbles would swell out in certain places where rivers entered the sea, and would thin out to comparatively small dimensions where no streams or only small ones came down to the coast, These old shingle-beds attain in the Rigi, and in the mountain called Speer, near Lucerne, a thickness of 5000 and 7000 Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Lyell, Charles, Sir, 1797-1875.
