to Folkestone, a bed of blue marl is seen of considerable thick- 

 ness : it is soft ; and the fossil shells which it contains generally 

 exhibit a pearly lustre. To the action of the sea on this soft 

 bed may be attributed the fall of the large masses of chalk which 

 form the under cliff near Folkestone. 



The chalk hills are covered with alluvial sand, of yellow and 

 red colours, and with gravel. 



A section of the strata, as shown along the cliffs from Folke- 

 stone to Walmer Castle, accompanies this paper. 



A letter was read from Capt. Carmichael, accompanying 

 drawings of the Table Mountain at the Cape of Good Hope. 

 The Table Mountain rests on granite, Green Point and the Table 

 Valley on schistus. The upper part of the Table Mountain con- 

 sists of sandstone in horizontal beds. The junction of the gra- 

 nite with the schistus is visible at Sea Point ; and here a very 

 confused mixture of the two rocks occurs. In some parts they 

 form alternate layers of various thickness ; in others, fragments 

 of the schistus, of all figures and sizes, lie imbedded in the granite. 

 Between this mixed mass and the pure schistus there is inter- 

 posed a rampart of granite, apparently differing from that which 

 composes the mass of the mountain, which for about 200 yards 

 is unmixed ; but as it approaches the schistus, becomes mingled 

 with it. 



Along the shore from Camp Bay to Sea Point are numerous 

 veins of trap in the granite.
