" Above the conglomerate is a series of beds of plastic 

 clay, slightly calcareous, and frequently arenaceous, with 

 crystals of selenite, gypsum, and numerous traces of vege- 

 tables which sometimes form an irregular seam of lignite." 

 "Associated with the terrestial debris are fresh-water Testacea, 

 of the genera Anodonta and Paludina, often cast in iron 

 pyrites, and much compressed." Stratum No. 2, is consi- 

 dered to represent the ordinary deposit of argile plasiique 

 of Paris, over which lies the thick deposit ofcalcaire grossier 

 proper. 



In conclusion, M. D'Orbigny considers, 



Istly, " That the genus Hamites existed until the end of 

 the cretaceous epoch, and that the chalk of the Paris Basin 

 contains turtles of a large size. 



2dly, " That the plastic clay of the neighbourhood of 

 Paris is indisputably separated from the chalk by a distinct 

 group, which may be named Calcaire pisoliiique tertiaire, 

 and which, from the nature of its organic remains, belongs 

 evidently to the palseotherian and tertiary, and not to the 

 cretaceous period. 



3dly, " That there evidently existed, during the accumu- 

 lation of the lower part of the plastic clay, several genera of 

 Mammalia, differing considerably from those discovered in 

 the upper series of the Paris Basin." 



Whilst, however, this fluviatile deposit is, in the neighbour- 

 hood of Paris, distinctly proved to be interpolated between 

 two well characterized portions of the calcaire grossier^ it 

 can, in Champagne, only be considered as synchronous with 

 the lower part of the eocene series. At Damery, the plastic
