over 300 feet in places and enter largely into the composition of the 

 country. (3) Wengen beds ; under these are included the plant-shales, 

 tuflfs, marls, and calcareous conglomerates, the characteristic fossils being 

 Posidon. Wengensis and Daonella Lommeli. (4) Dolomites and lime^ 

 stones which succeed are, for petrographical reasons, placed under a sepa- 

 rate head, as St.-Cassian beds ; but it is not held that they are precisely 

 parallel to the true St.-Cassian deposits. (5) Eaibl beds, which yield 

 a fine marble. Outside the area of the map, a higher group (Haupt- 

 dolomit) is seen with a thickness of 1300 feet. The Carboniferous 

 beds occupy a narrow strip along a line of dislocation, the age of which 

 must be subsequent to the deposition of all the Triassic beds ; parallel 

 to this are the veins of quicksilver, whose origin must therefore be con- 

 nected therewith. E. B. T.

 A description of the geology of the country around Ampezzo in the 

 Alps, including part of the border-land between Tyrol and Yenetia. 

 The memoir contains a mass of stratigraphical details. It is accom- 

 panied by a chrome -lithographed geological map, and by two plates of 

 sections. F. W. R.

 A vindication of his explanation of the fan-shaped structure and of 

 the intercalated wedges of Jurassic limestone in the gneiss of the Ber-

 The hill of Bocheggiano contains a quartz-vein which separates the 

 variegated schists (Jurassic ?) from the Eocene rocks, but is said to be 

 perfectly conformable to the latter, though altering them for a few feet 

 at the contact ; it contains copper-ore. The hill of Montieri contains 

 the Jurassic schists, surmounted by Upper Jurassic limestones and sand- 

 stones. In other places the variegated schists are seen to lie upon the 

 M. Lias (red marble with Ammonites), while above come Cretaceous 

 and Eocene rocks. E. B. T.
