tain beds are observed in the form of an S, com* 

 pressed, or of which the bendings are very 

 strongly marked. These S's are often repeated, 

 sometimes in contrary directions, and masses of 

 rocks are found between them, whose stratifi- 

 cations are not distinct. When these contorted 

 beds are closely observed, it is found that they 

 are often broken in the strong curvatures ; and 

 this proves that they were not formed in that 

 . position/ 



cc The third place is opposite the preceding, 

 on the other side of the lake : c It is a mountain 

 in which the beds, which are nearly horizontal 

 below, turn up above and form a C, whose con- 

 cavity looks to the N. N.E. : on the left, or to 

 the S. S.W. of the C, there is a large hollow; 

 and what is most remarkable is, that the beds 

 which adjoin the lower branch of the C extend 

 themselves to a great distance, forming a moun- 

 tain with regular and horizontal beds.' 



" From these facts Saussure concludes that 

 these dislocations of beds are produced by a re- 

 foulement, or repressure, which has folded them 

 over each other."* 



Calcareous rocks seem to be comparatively 

 rare in Africa, and even in Asia. As layers of
