The Rhcetian Alps. The older geographers included under the term Rhastian Alps a vast mountain region extending over 6 of long., from the east side of the Lago Maggiore to the left bank of the Salza, and through 2- of lat., from the neighbourhood of Brescia to the plain of Bavaria. There is no assignable reason for uniting in a single division mountain groups so distinct as many of those included within this wide space scarcely less than that occupied by all the divisions hitherto enumerated save the fact that at an early period they received a com mon designation from writers who had a most imperfect acquaintance with their topography. It might be expe dient to discard a term to which it is difficult to assign a limited meaning without incurring the risk of confusion ; but general usage has so constantly applied the term Rhaetia to the mountain region of Switzerland lying east of the Rhine, with the adjoining portion of Tyrol, that it seems best to preserve the ancient name while endeavour ing to restrict it within juster limits. With that object it is necessary to take account of one of the most remarkable features in the orography of the Alps the great breach in the continuity of the main chain shown in the upper valley of the Adige. On a general view of western Tyrol it is apparent that the lakes which feed the head of that stream lie on the northern side of the axis of elevation of the main chain, and in fact several streams draining the northern slopes of the central mass are borne southward to the Adriatic through that opening. This is not the place to take into consideration the important influence that this breach in the line of defence between Italy and the north, and the equally deep opening of the Brenner Pass at the head of the other main branch of the Adige, has had on the history of Europe, nor to discuss the geological significance of the same depression throughout an incalculably longer period ; but it is sufficiently clear that this should be taken as the eastern limit of the group to which the term Rhsetian Alps most properly applies. On the west the limit, as we have already seen, is marked by the valley of the Rhine, and the line of depression over which the Spliigen road is carried to the head of the lake of Como. In the space between these boundaries the chief mountains of the Rhsetian Alps appear as islands of crystalline rock, divided by intervening masses of palaeozoic and older secondary strata; but on the south side lies a district which differs considerably in geological structure, and is cut off by a distinct orographic boundary. A straight line drawn from the head of the lake of Como to Cles in Tyrol, will throughout lie close to a trench formed by the valley of the Adda, the low pass of Aprica, the head of Val Camonica, the Tonale Pass, and the Tyrolese Val di Sole. On the south side of this trench, and parallel to it, extend in succession a broad band of palaeozoic rock and a still broader zone of trias, bordered on the southern slope by a narrow girdle of Jurassic rocks which decline towards the plain of Lombardy. Towards the east these are interrupted by a great mass of very peculiar granite, the most consider able tract of true granite to be found in the Alps. Beyond this the ridges and valleys no longer preserve the direction from east to west, but become parallel to the lake of Garda and the valley of the Adige. The district thus limited is enumerated hereafter as a distinct division under the designation Lombard Alps, the boundary between this and the Rhtetian division being the trench above described, which is prolonged from near Cles over the low Gampen Pass to the neighbourhood of Meran. On the northern side the Rhsetian Alps are divided from the Vindelician by a well-marked trench closely corresponding with the northern limit of the crystalline rocks of the Silvretta group, formed by the valley of the 111, the Vorarlberg Pass, and the course of the Rosanna. Within the limits here assigned the Rhsetian Alps occupy an area measuring about 80 miles by 60. The entire mass is divided into two nearly equal portions by the upper valley of the Inn, known in Switzerland as the Engadine.

Lombard Alps. The limits of the Lombard Alps have been already pointed out. They are enclosed on the east and west sides by the Adige and the lake of Como, extending through about 90 miles from near Meran to Lecco. Their northern boundary is the great orographic trough that stretches from the head of the lake of Como along the valley of the Adda to Tresenda, thence by the low Aprica Pass to the upper Val Camonica, and over the Tonale Pass to the Val di Sole. Where that valley bends abruptly to SSE., the trough still keeps its original direc tion across the Gampen Pass to the right bank of the
Adige below Meran. In spite of the zeal with which
