 peaks, but it is so shut in by the other mountains, that it is seldom seen except from a distance, and then is usually confounded with the neighbouring summits. Its name has been accidentally omitted on the map, but its situation is represented by the large patch of rocks, nearly surrounded by glaciers, that is seen between the words Ailefroide and Mt. Pelvoux.

The lowest depression on the main ridge to the south of the Aléfroide is the Col du Selé, and this, according to Mr. Tuckett, is 10,834 feet. The ridge soon rises again, and, a little farther to the south, joins another ridge running nearly east and west. To a mountain at the junction of these two ridges the Frenchmen have given the singular name Crête des Bœufs Rouges! The highest point hereabouts is 11,332 feet; but a little to the west there is another peak (Mont Bans) of 11,979 feet. The main ridge runs from this last-named point, in a north-westerly direction, to the Cols de Says, both of which exceed 10,000 feet.

It will thus be seen that the general elevation of this main ridge is almost equal to that of the range of Mont Blanc, or of the central Pennine Alps; and if we were to follow it out more completely, or to follow the other ridges surrounding or radiating from it, we should find that there is a remarkable absence, throughout the entire district, of low gaps and depressions, and that there are an extraordinary number of peaks of medium elevation. The difficulty which explorers have experienced in Dauphine in identifying peaks, has very much arisen from the elevation of the ridges generally being more uniform than is commonly found in the Alps, and the consequent facile concealment of one point by another. The difficulty has been enhanced by the narrowness and erratic courses of the valleys.

The possession of the 'advanced copy' of sheet 189 of the French map, enabled Mr. Tuckett to grasp most of what I have just
