386 APPENDIX. No. IV. 



where, from the general strike of the beds, we should 

 expect to find the Silurian limestone underlying the 

 coal-bearing sandstones, that this limestone does occur, 

 and contains a "fossil, T. aspera, eminently characteristic 

 of the Eifelian beds of Germany, which form, in that 

 country, the Upper Silurian strata. 



No. V. CAPE HAMILTON, Baring Island (Lat. 74° 15' N. ; Long. 



117^ 30' W.). 



1. Greyish-yellow sandstone, like tliat found in situ in Byam Martin's 



Island. 



2. Coal. — The coal found in the Arctic regions, excepting that 



brought from Disco Island, West Greenland, wliich is of tertiary 

 origin, presents eveiywhere the same characters, which are some- 

 what remarkable. It is of a brownish colour and lignaceous 

 texture, in fine layers of brown coal and jet-black glossy coal 

 interstratified in delicate bands not thicker than paper. It has 

 a woody ruig under the hammer, recalling the peculiar clink of 

 some of the valuable gas coals of Scotland. It burns with a 

 dense smoke and brilliant flame, and would make an excellent 

 gas coal ; and, in fact, it resembles in many respects some 

 varieties of the coal which has acquired such celebrity in the 

 Scotch and Prussian law-courts, under the title of the Torbane 

 Hill mineral. 



No. VI. CAPE DUNDAS, Melville Island (Lat. 74° 30' N. ; Long 



1130 45' W.). 

 Fine specimens of coal. 



No. VII. CAPE SIK JAMES EOSS, Melville Island (Lat. 74° 45' N. ; 

 Long. 114° 30' W.). 

 Sandstone passing into blue quartzite. 



No. VIII. CAPE PKOVIDENCE, MelviUe Island (Lat. 74° 20' N. 

 Long. 112° 30' W.). 



A specimen of crinoidal limestone, apparently similar to that oc- 

 curring in Griifith's Island, from which, however, it could not 

 have been brought by the present drift of the floating ice, as the 

 set of the currents is constant from the west. If brought to its 

 present position by ice, it must have been under circumstances 

 differing considerably from those now prevailing in Barrow's 

 Strait. 



Yellowish-grey sandstone. 



Clay ironstone passing into pisolitic hematite. 



No. IX. WINTEE HAEBOUE, Melville Island (Lat. 74° 35' N. ; 

 Long. 110° 45' W.). 

 Fine yeUow and grey sandstone.
