eastern part of the Carpathians ; some parts of the Hartz ; and 

 the denudations of the Bray country, of the Wealds of Surrey, 

 of Sussex, and of Kent. I shall not repeat here the distinction 

 it is necessary to make between the denudations and upheavings 

 of beds produced by elevation, and those denudations which re- 

 sult only from convex surfaces covered by gently inclined beds. 

 (See Bull, de la Soc. Geol. de France, vol. ii. p. 23 ; or Resum^, 

 pour 1832, p. cii. et. cxvi). To give an extreme example, I 

 may remark, that the denudations, elevations, or chalky craters of 

 elevation at Beine near Grignon, and at Meudon near Paris 

 (p. 655) y have not yet been admitted by geologists. 



Other examples correspond exactly with what 1 have said 

 upon this subject in my Memoires Geologiques ; for every where 

 the greensand has been dislocated and elevated to a great height. 

 But the direction of these redressemens does not seem to be the 

 same in different countries ; and I do not see that coincidence 

 which M. de Beaumont perceives. For instance, in the eastern 

 Carpathians, the dislocations, as well as thejongitudinal valleys, 

 run N.W. and S.E., and these disturbances are contemporaneous 

 with those which have lifted up the other or western part of the 

 Carpathians from N.E. to S.W. (See Bullet, de la Soc. Geol. vol. iv. 

 p. 73.) M. de Beaumont has concluded, from the examination 

 of maps, that the chain of the western Carpathians is parallel 

 to the Western Alps ; and hence draws the conclusion that their 

 upheaving coincides. Now, if he had been on the spot, he would 

 know that the stratification of the beds forms a kind of diagonal 

 line with the direction of the higher part of the chain ; so that if 

 the last corresponds with the direction of the Western Alps, the 

 upheaving of the beds has taken place in a different line. One 

 of two things must be the case; either the strata intfac Western 

 Alps and Carpathians not being parallel, must belong to two 

 different elevations, or, what is more probable, these two ancient 

 table-lands were at the same epoch upheaved and upturned in 

 directions somewhat different. At the foot of the Carpathians 

 alpine blocks are unknown, and the old alluvium, as well as the 

 newest tertiary deposits, are horizontal, but the molasse has been 

 upheaved, as along the Western Alps. 



I do not see how it is easy to get rid of the disagreviens of 

 partial accidens parallel to the directions of other older eleva-
