The authors consider the lower group to correspond with the calcaire grossier and Palæotherian deposits; the middle to the English crag, and middle subapennines. According to M. Dufrenoy, the former would rather appear to belong to the middle tertiary period. In his latest memoir on the Alps and Carpathians, Sir R. Murchison expresses the conviction that the flanks of the Alps exhibit a true transition from the younger secondary into the older tertiary strata, and that the older supracretaceous rocks occur abundantly, and well characterized, in the South of Europe, extending thence eastward into Asia. The cretaceous beds, containing inoceramus and ananchytes, are conformed in position to the overlying tertiary rocks characterized by nummulites, and in this latter series we still find gryphæa vesicularis.
