IV. — Ernest Favre on the Geology of the Alps.^ 



THE group of mountains which forms the subject of this little 

 work lies between Chatel-Saint-Denis and the valley of the 

 Sarine ; it is composed of Niremont and the Corbettes, of the Moleson 

 group, and of a part of the Verreaux chain. 



The work is divided into two parts : the first is devoted to a 

 geological description of the area, illustrated by plates of sections ; 

 the second, to a special study of the strata and of the organic remains 

 found in them. 



The structure of Niremont is shown to be that of an inverted fold, 

 the crown or apex of which does not occur at the highest part of the 

 mountain, and this is also the case with Corbettes, which presents two 

 inverted folds. The Moleson group forms an elongated mass, 

 stretching in a north-east and south-west direction, and isolated 

 from the surrounding mountains ; its structure is very regular. On 

 whatever side one climbs, one reaches from the base to the summit 

 more and more recent beds of Jurassic and Neocomian age, which 

 dip on either side (north-east and south-west) towards the centre. 

 Further to the east, at the foot of the mountain mass, the lie of the 

 strata is different. Here Ehaetic and Triassic beds are met with, 

 highly inclined, and, indeed, plunging beneath the mountain mass. 

 These beds are repeated further East, owing to an anticlinal. 

 The Verreaux chain forms an abrupt escarpment to the West, the 

 beds dipping gently to the East. Jnrassio and Cretaceous strata 

 form this ridge. 



The author then turns his attention to the palaeontology of the 

 beds, which include the Triassic, Ehaetic, Liassic, Oolitic, Neocomian, 

 Cretaceous, and Tertiary strata.

 Carolina Marl Bed." By F. S. Holmes, pp. 87. (London :

THE object of this pamphlet is to give a popular and scientific 

 view of the origin and geological position of the Phosphate 

 rocks, to point out their chemical and agricultural value, and to 

 record the history of their discovery and development. 



The " Great Carolina Marl Bed " is regarded as of Eocene age. 

 It is extensively developed on the Ashley and Cooper Eivers, where
