Further eastj about 100 yards west of some stakes driven into 

 the beach, where the White Band comes to the base of the chfF, it 

 contains occasional large white nodular concretions 10 inches thick 

 and a yard long, while above it are two bands of clay-ironstone, 

 each one inch thick. 



Section measured easUoard of the preceding section, where the 

 lohite hand a.pj)ears at the base of the cliff.

Further east of the place where the above section was measured, 

 all the bands forming the White Band unite, and are well seen in 

 the clitf, forming a distinctly marked white line at its base, with 

 about twelve feet of dark clay weathering brown above. 



The next three sections helj) to fill up the gaps in the beds 

 between the White Band and the Black Band. 



About S.E. of the buoy the following section was measured in a 

 projecting point of the undercliff.
