in a marshy bottom for the canal, in alluvial soil, where

 found, p. 59. 



Sevres, 7 miles \V., has quarries of coarse llmestmie and 

 sand, in which ate found the 13 fossil remains nien^ 

 tioned at Meudon, Near the glass-house, the mass of 

 chalk (that underlays the above), is elevated near 50 

 feet above the Seine, and is apparently the highest part 

 of it in the basin of Paris ; the strata upon this elevated 

 part seem thinner than usual, and the stone is sensibly 

 inclined towards the Seine, (probably these appearances 

 are occasioned by a fault and consequent lilt of the 

 strata, as these are the only inclining strata that are 

 mentioned in all the basin of Paris) p. 43 and 47, 



Sezanrw, 48 miles SE. by E., is at the south-eastern edgQ

Trappe, 14 miles SW., has hard siliceous limestone strata, 

 which quickly perish q\\ exposure to the air and rain ; 

 and such is here used for marling the land : in these 

 strata burstones (French Burs) are found, withlymne^e 

 and planorbes shells and gyrogonites, supposed to be 

 of fresh-water origin, p. 56 and 57. ^ 



Triel, y has plaster quarries on the mountain, 



that are situate at an extremity of the gypsous (hstrict, 

 in which only the first mass of gypsum is seen (as at

 limestone (and its accompanying Ibssils as at Gentilly)* 

 p. 49 and 53. 



Vaucienne Valley has madrepores, with camerines and other

Versailles Park, 14 miles SW., is situated in a strait 

 between two hills (or in the inosculation of two oppo- 

 site valleys) where the gypsum formation has no plaster 

 beds in it, but green inarles containing nodules of 

 slrontian prevail, p. 38 and 53. 



Ville-d'Avray^ 8 miles W., has plaster quarries in some 

 places, and in others only thin strata of plaster in the
