The Traveller's Guide through Switzerland: in four parts (1820) by Johann Gottfried Ebel, Daniel Wall
Under this denomination are the mountains that divide Italy from France and Switzerland; it should be understood, however, in a more general sense. The Alps, properly speaking, extend from the borders of the Rhone, in the south of France, to the frontiers of Hungary, a space of twelve degrees of longitude. They traverse Provence and Dauphine in France; the whole of Savoy; a great part of Piemont; and in the new Lombardo Venetian kingdom, the Milanese the Venetian states; again the whole of Switzerland, the Tyrol, Salzbourg, Carinthia, Carniola, Styria, Croatia, Sclavonia, the southern parts of Bavaria, Swabia, and of Austria. In breadth they are from two to four degrees of latitude. At all times, even during the greatest heats of summer, the summits of the higher Alps are always coated with snow of a dazzling whiteness.
