at the Kielerbach has been so often described ^ that a brief notice 

 may suffice. Here the Drift, which at first sight appears to be 

 interstratified with the Chalk, dips at an angle of 30° (approxi- 

 mately). The lower clay (identical with that seen in the same 

 position at several other places on the coast) is dull grey, and 

 contains pebbles of various rocks (including a dark limestone, but, 

 so far as we saw, no chalk) as well as a few small boulders of 

 crystalline rock from 12 to 18 inches in diameter. The exact 

 thickness of this clay is not easily ascertained, but it is certainly 

 not less than 18 feet (fig. 4, p. 316). Above it, with a sharp line of 

 division, is sand (at the bottom of which we sometimes find a well- 

 marked layer of stones) ^ about 15 feet thick. This sand is clearly 

 but rather irregularly stratified, being occasionally false-bedded and 

 in places slightly clayey. Above this comes another clay, con- 

 taining some stones, but rather more sandy than the lower one. 

 Its thickness in the section more particularly studied was about 

 4 feet ; but this evidently was only a fragment. Chalk rises up in 

 the cliff north of the section and seems to overlie the Drift on the 

 south (fig. 5). On the former side the surface of the Chalk i&

certainly uneven, becoming rather steeper in the neighbourhood of 

 the beach, and on the latter side it is represented as irregular 

 by earlier observers. 



Another section, about \ mile to the south, shows the same set 

 of beds seemingly intercalated in the Chalk and dipping at about the
