ville, south of 75° 50' ; Baring (or Banks) Land, 12\°— 741° N.,

" (5.) Jurassic rocks : over a small peninsula on the eastern 

 side of Prince Patrick Land ; also at islets Exmouth and Talbe, 

 north of Grinnell Land ; in long. 95° W.,lat. 77° 10' N. 



u Viewing the range or direction of the whole, the line between 

 the " Carboniferous limestone" and the " coal-bearing sandstones," 

 according to the map, is nearly straight between E. 5° N. and W. 

 5° S. In the coal-bearing sandstone region, two parallel outcrops 

 of coal are marked as existing on Bathurst Land and southeastern 

 Melville Island, and on the intervening island of Byam Martin, the 

 distance between the two lines eight or ten miles ; also a third out- 

 crop in Melville Island, and along the same line in Baring Land 

 to the southwest. The strike is represented as uniform between 

 E.N.E. and W.S.W., and is deduced from the observed occurrence 

 of coal at Cape Hamilton on Baring Island, Cape Dundas on Mel- 

 ville Island, also Bridport Inlet and Skene Bay on Melville Island ; 

 on Byam Martin Id. ; and at Schomberg Point and Graham Moore 

 Bay on Bathurst Island." 



In addition to this series there are interesting tertiary deposits 

 containing lignite, described in the following extract from Dr. Arm- 

 strong's voyage of the Investigator. The wood is probably like 

 that of the present arctic sea, drift trunks. 



" On ascending one of these hills, about a quarter of a mile from 

 the beach on its side, about 300 feet high from the sea-level, we 

 discovered the wood of which we were in search. The ends of 

 trunks and branches of trees were seen protruding through the 

 rich loamy soil in which they were embedded. On excavating to 

 some extent, we found the eutire hill a ligneous formation, being 

 composed of the trunks and branches of trees ; some of them dark 

 and softened, in a state of semi-carbonization. Others were quite 

 fresh, the woody structure perfect, but hard and dense. In a few 

 situations, the wood, from its flatness and the pressure to which it 

 had for ages been exposed, presented a laminated structure, with 

 traces of coal. The trunk of one tree, the end of which protruded, 

 was 26 inches in diameter by 16 inches ; that of another, a portion 

 of which was brought on board, was 7 feet in length, and 3 feet in 

 circumference: and dense in structure,although pronounced then to 

 be pine.* Other pieces, although still preserving the woody .struc-

 Royal Dublin Society, Dublin. To the obliging kindness of its able
