WHITAKEK TERTIARY CLIFF-SECTIONS.

At one place the sand (3) seems to abut against the beds below, 

 as if from a small fault. 



At VarengevULe, beyond the next gap, is a like section, the sand 

 (8) and its included masses of sandstone being in great part white, 

 and there are also sandy shell-beds. The Oldhaven sand is hidden 

 by fallen masses from above. 



At the next hill the top part of the London Clay contains a bed 

 of buff sand 2 feet thick. 



In Passy's work a mass of Calcaire Grossier (?) is figured (plate 

 xix.) as resting unconformably on the beds below. I did not see 

 it ; but it may have fallen into the sea since his time. 



Inland there is a tile-kiln in the London Clay. 



2. Newhaven. 



The section here was, I believe, at its best when I saw it, the 

 cliff having been then cut back to the highest ground ; and for 

 this reason I venture to describe it to the Society, although it has 

 already been described at least five times (three times in the Society's 

 publications), and in all these cases by well-known observers, so 

 that, of course, I shall incorporate their notes with my own. 



The shape of the outliers will be seen from the accompanying- 

 map (fig. 1), which differs from that of the Geological Survey in 

 separating the Tertiary beds into two masses, instead of joining the 

 whole into one along the face of the cliff. I believe that the mass
