erable deptli.aud present certain remarkahle modifications. 

 Tlie section observed at this place is as follows :

1. Hani gray laininatcd clay, FornminiJ'tra and Leila, in thin 



layers 7 



2. Red layer, in two bands <)

f). Hard bnff sand, very tine and laminated 1.1

very irregularly disposed 4

The wliole of these deposits, except the Leda clay, are 

 very irregnlarly bedded, and are apparently of a littoral 

 character. They seem to show the action of ice in shallow 

 water before the deposition of the Leda clay. The only 

 way of avoiding this conclusion would l)e to suppose that 

 the underlying beds are really of the age of the Saxicava 

 sand, and that the Leda clay has been placed al)ove them 

 by slip[)ing from a higher terrace ; but I failed to see good 

 evidence of this. A little farther west, at the gravel pits 

 dug in the terrace for railway ballast, a deep section is 

 exposed, showing at the top Saxicava sand, and Ijelow this 

 a very thick bed of sandy clay with stones and boulders, 

 constituting apparently a somewhat arenaceous and par- 

 tially stratified equivalent of the boulder-clay. A little 

 above this place, at the brick-works, the Saxicava sand 

 is seen to rest on a highly fossiliferous Leda clay, which
