and mineral character of the rock are perfectly distinct. Other 

 smaller masses, included in the serpentine, will be noticed on the 

 shore, in some cases indicating by their peculiar jointing that they

 have been subjected to heat. Clambering on at the base of the serpen- 

 tine crags, we enter a small bay with a narrow shore, almost divided 

 into two by a slight projection. Soon after entering the nearer of these 

 we pass, at the base of the cliff, two small intrusive gabbro veins, 

 the nearer at most about two feet thick and branching, the other 

 about half as much. The rock is dark in colour, partly owing to 

 staining from the serpentine, and rather coarse. This bay also 

 exhibits well the relations of the schist and serpentine. The luxu- 

 riant herbage generally masks actual junctions, except in one place 

 near the base of the cliff, where the serpentine may be seen gradually 

 passing across the broken ends of the beds in the schist ; but 

 without this evidence the relations of the schist and serpentine in the 

 cliff cannot be wholly explained by faults. 



A gabbro vein in thehornblende schist should be noticed; it is about 

 half a yard thick, and in form a rude rhomboid (fig. 2). It exhibits a
