324 MACCULLOCH, GEOLOGY OF BAFFIN'S BAY. 



XL. — Geological Notes on Baffin's Bay. By J. Ross 

 and MacCulloch, 1819. 



From miscellaneous specimens brought home from Davis's 

 Strait and Baffin's Bay by Capt. John Ross, and determined by 

 Dr. J. MacCulloch (Ross's " Voyage of Discovery," &c., 2nd. 

 edit., 1819, 8vo., vol. ii., pp. 121-141), it appears that: — - 



(1.) At Waygatt Island (70° 36' N. lat., 54° 40' to 55° W. 

 long.) and at Four Island Point (70° 46' N. lat., 53° 3' W. long.) 

 there are granite, gneiss, schists, and igneous rocks, with lignite 

 at the former place. 



(2.) At the Three Islands of Baffin (74° 1' N. lat., 57° 25' W. 

 long.), gneiss abounding in garnets and containing molybdena. 



(3.) Cape Melville, granite and porphyry. 



(4.) Bushnan Isle (^36° 04' N. lat., 65° 66' W. long.), granite, 

 gneiss, and mica-schist ; claystoue and amygdaloidal claystone. 



(5.) Cape York, Esgicim., Inmallick (76° N. lat., 66° 46' W. 

 long.), porphyritic greenstone, used by the natives in cutting off 

 (heir iron from the masses. 



(6.) Between Cape York and Cape Dudley-Digges, including 

 the Crimson Cliffs (from 75° 45' to 76° 10' N. lat., and from 67° 

 to 68"* 40' W. long.), granite, gneiss, and mica-schist, and green- 

 stone. 



(7.) From Possession Bay and Cape Byam-Martin, on the west 

 side of Baffin's Bay (73° 33' N. lat., 77° 28' W. long.), granite, 

 gneiss (with pyrites, garnet, and green felspar), sandstones, shale, 

 limestone, jasper, siliceous schist, and igneous rocks and agates. 

 " The gneiss with green compact felspar appears to be of common 

 " occurrence on this coast . . . . ; it is exactly similar to that 

 " which occurs abundantly in the Western Isles, and more par- 

 " ticularly on the western coast of Ross-shire, prevailing particu- 

 " larly about Loch Ew and Loch Greinord [Laurentian]." " The 

 " jasper, siliceous schist, and chert resemble exactly those spe- 

 *' cimens Avhicli are found in the Island of Sky, among the beds 

 *' of shale, sandstone, and limestone [Jurassic], when these are 

 " immediately in contact with the larger masses of trap ; and 

 " probably they here also owe their origin to the same cause." 



(8.) From Agnes Monument (70° 37' N. lat., and 67° 30' W. 

 long.), granite, gneiss, and graywacke-schist. 



(9.) The Iron mentioned above, under " Cape York," is stated 

 by Capt. Ross to have been used by the " Arctic Highlanders " 

 of Prince-Regent's Bay (lat. 75° 54', long. 65° 53'), for the 

 edges of their knives, and to have been obtained by them from 

 the mountains near the coast, behind Bushnan Island. It was 

 said by the natives, as interpreted by Sacheuse, to occur in several 

 large masses or jjieces, of Avhich one in particular, harder than 

 the rest, was part of the mountain. The Iron was cut off with 

 a hard stone, and then beaten into small flat oval pieces. The 

 place where the metal was found was called "Sowallick," and
