The photo-plate here given (Fig 15) shows part of the 

 great terminal moraine of the Scandinavian ice-sheet 

 resting on chalk at Specton, north of Flamboroiigh Head, 

 530 feet above the sea, and Mr. Kendall informs me that 

 he has found in it characteristic Norse rocks, close to the 

 windmill here shown. Other portions of this great moraine 

 formed of boulder-clay, with numerous embedded ice-worn 

 blocks of Scandinavian origin as described by Professor

WITH NORSE ERRATICS. 



Sedgwick, are seen in the cliffs at Thorn wick, Flam- 

 borough Head, resting on chalk, (see Fig. 16 on next page), 

 from a beautiful photograph by Mr. Bingley; and the 

 same gentleman has given me the fine view of the cliffs of 

 similar boulder-clay of great thickness resting on inclined 

 strata of upper oolitic rocks further north, which, Mr. 

 Kendall informs me, are striated from the north-east, and 

 contain Scandinavian erratics (Fig. 17).
