5. Many of these larger pieces bear marks of

 above the level of the sea, it is generally 

 associated with the bones of whales ; so that I 

 think all these facts taken together make np a 

 pretty conclusive case against the in situ 

 suggestion. 



This island, as well as all the other off-lying 

 inlets and skerries on the south south-east and 

 south-west of Spitzbergen (I do not include 

 Hope Island), is composed of a rough coarse-
