clay with its characteristic fossils, may be seen underlying 

 the calcaire grossier, but its position with regard to the sac- 

 charine fossiliferous limestone of Mont Aime and Vertu * 

 (imagined to be the equivalent of the calcaire pisolitiqiie), 

 is yet uncertain, although the latter reposes, in some places, 

 immediately upon the chalk, and in others, is only separated 

 from it by a few feet of clay, containing remains exclusively 

 marine. At neither ofthese localities,however, where this lime- 

 stone varies in thickness from 60 to 100 feet, is it overlaid by 

 strata sufficiently well characterized to establish its superpo- 

 sition ; neither do the organic reliquice afford us much informa- 

 tion, for the species of none of the Testacea have yet been 

 recognized, in consequence of their almost invariably occur- 

 ring in the state of casts : as a group, however, this deposit 

 appears to exhibit a close analogy to those of the calcaire pi- 

 solitique of the neighbourhood of Paris. Still I obtained 

 from this locality, a few very perfect specimens of the teeth 

 and bones of reptiles and sauriaus ; also some palates and 

 teeth of Squalus and other fishes.
