with very little felspar or quartz, and intersected by- 

 thin veins of elvan composed of quartz and white felspar. 

 The cooking utensils of the natives are made from this 

 fine schist, in preference to any other description of 

 rock. 



3. Woman's Islands. — These islands, off the west coast 

 of Grreenland, are composed of a garnetiferous mica 

 slate, formed of black mica in layers, with alternating 

 plates composed of white felspar and quartz, and filled 

 with fine garnets, rose-coloured, vitreous in fracture, and 

 transparent. 



4. Cape York, lat. 76° N., Greenland. — This cape is 

 composed of a fine-gi-ained granite, consisting of quartz, 

 white felspar, with minute specks of a black mineral, of 

 pitchy lustre, composition not yet determined. 



5. WolstenJiolme and Whale Sounds, lat. 77° N., 

 Greenland. — At Wolstenholme Sound the granitoid 

 rocks of Greenland become converted into mica slate 

 and actinohte slate of a remarkable character. The 

 mica slate is composed of large plates of an intimate 

 mixture of black and white mica, the chemical examina- 

 tion of which will doubtless prove of interest. These 

 plates of mica are separated by bands of pure wliite 

 felspar. The actinolite slate is dark green, and formed 

 by an almost insensible gradation from the mica slate. 

 In the low ground between Wolstenholme and Whale 

 Sounds, the granitic rocks cease, and are covered by 

 deposits of fine red gritty sandstone, of a banded struc- 

 ture, and a remarkable coarse white conglomerate. 

 The boundary between these formations is also marked 

 by the development of masses of dolerite and clayey 

 basalt. 



6. Carey's Islands, 76° 40' N"., Greenland, lie to 

 the westward of Wolstenholme Sound, and are com- 

 posed of a remarkable gneissose mica schist, formed of 

 successive thin layers of quartz gi-anules, containing 

 scarcely any felspar, and layers of jet black mica, with
