I. — On some Inclusions in the Great Whin Sill of 



Northumberland. 



By John Armstrong Smythe, Ph.D., D.Sc. 



(PLATE XVII.) 



THE inclusions to be described in this paper occur in the Whin Sill 

 at Snook Point on the coast of Northumberland. This is the 

 most northerly exposure of the whin in the coast-section which 

 stretches fi'om Culleruose Point, through Dunstanburgh, to Beadnell 

 Sands; and it is here that the outcrop leaves the coast and sweeps 

 out to sea, to reappear further north in the Earne Islands and, on the 

 mainland, at Bam burgh. 



The exposure at Snook Point is a thin sill, one of two into which 

 the whin seems to be split in this neighbourhood. It occupies the 

 foreshore in the form of a triangular patch, about 70 yards broad at 

 the shore-end, from the apex of which a spur is sent out to sea, in an 

 easterly direction, for several hundred yards. The dip is south at 

 a gentle angle, and the wliin rests on sandstone and is overlain by 

 limestone (the Great), both contacts being metamorphosed. The
