considerable extent and of rather tolerable quality. The specific 

 gravity of the coal is 1-3848, and the following analysis of its 

 proximate ingredients,- made by Dr. Fyfe, Professor of Chemistry, 

 King's College, Aberdeen, upon a specimen obtained from the same 

 source as that now in the Museum of this Society, enables us to 

 judge of its value and purity : —

I have not myself visited the beds of this mineral, but from the 

 recent elaborate researches of Dr. H. Rink, the enterprising Dan- 

 ish traveller, it appears that sandstone is associated with this coal. 



At Cape Cranstounc, situate on the north side of North-east 

 Bay (Omenak Fiord), and immediately adjacent to the above two 

 localities, the trap-rocks again occur, and thence extend northward, 

 apparently in one unbroken series, as far as Proven, in hit. 72° 20'. 

 Northward of this to Cape York, lat. 76°, with one or two slight 

 exceptions, in lat. 73° 20' and lat. 74°, the numerous islands and 

 every part of the coast that protrudes from beneath the glacier are 

 composed of gneiss and granite. 



. Capes York and Atlioll. — At Cape York, lat. 76°, and on to 

 Cape Atholl, thirty to forty miles further north, although differing 

 in outline, owing to the glacial accumulation, from Disco Island 

 and other well-known parts of the coast to the southward, the rocks 

 can be referred with certainty to the same trappean formation. 

 Specimens of greenstone-porphyry were taken from the cliffs at 

 Petowak, near Cape Atholl. 



Wolstenholme Sound to Cajje Hatherton. — Northward of Cape 

 Atholl we find, in the entrance of Wolstenholme Sound, a flat 

 island (Saunders Island), which from its distinctly stratified ap- 

 pearance suggests the commencement of a different series of rocks. 

 And eastward of the same cape, on the south shore of this Sound, the 

 strata are seen cropping out with a dip to the south-west. This is 

 at variance with what we observe in Saunders Island, about twelve 

 miles N.N.W., for there the strata are perfectly horizontal. At 

 North Omenak a sandstone, or slaty quartzose grit, with a dip of 

 about 15° to W.S.W., occurs inters tratified with greenstone- 

 porphyry ; and it is very probable that Mount Dundas, a tabular 

 hill with a talus, is also composed of igneous rock. At the top 

 of Wolstenholme Sound, in the same bluff, the strata, dipping 

 about south-west, vary in their inclination from 10° to 25° or 30°. 



In Granville Bay, about twenty miles farther north, the strata 

 are at one place but little out of the horizontal, and at another the 

 dip is about 45° to the north-west, and at another we have strata 

 somewhat curved. In the entrance of Granville Bay several small 

 islands occur which are probably formed of trap-rock. In Booth 

 Sound, lat 77°, near Cape Parry, there is a very remarkable bell- 

 shaped rock (Fitzclarence Rock), of a dark colour and rising in an 

 isolated form to a height of probably 500 or 600 feet, as if from 

 out of a comparatively level spit of ground this also appears to
