67. 18 feet : shales and brownish sandstone with 1 inch seams 

 of shale. 



68. 20 feet : soft shales. 



69. 12 feet: hard grey sandstone. 



70. 5 feet : laminated shales. 



71. 10 feet: hard greyish sandstone. 



72. 3 feet : shales and sandstones ; and 6 feet : sandstone. 



73. 8 feet : laminated shales and sandstones. 



74. 8 feet : hard grey sandstone. 



75. 80 feet : irregular shales, sandstones, &c., so high up as to 

 be indistinct ; and below covered by debris. 



76. Coal, 1 foot. 



77. White sandstone, 2 feet. 



78. Splintery shales, 4 feet. 



79. Hard greyish sandstone, 20 feet. A narrow spur from trap 

 dyke (C) runs perpendicularly through this. 



80. Irregular seams of sandstone, shale, &c., about 25 feet. 



81. Hard grey sandstone, mostly washed by the torrent. 

 Between this and 82 a trap dyke (Cj runs. Its course is N. 



Mag., rising in the direction of the Atanekerdluk basaltic headland, 

 intersecting the beds at an acute angle, and about at right angles 

 to "A"and*^B"dykes. 



82. Irregular beds of sandstone shales, to about 45 feet. 



83. Grey sandstone, 8 feet. 



84. Brownish, hard sandstone, 4 feet. 



85. Black shaly coal (?), 6 feet. 



86. White gritty sandstone, with perhaps a layer of shale 

 intervening, 60 feet. 



Leaving the ravine. Dr. Brown crossed to a ravine, which 

 unites with the main valley at dyke " C," and thence he continued 

 the section : — 



87. Here were exposed, from the bed of the stream to near the 

 pinnacled summit of the hill, about 80 feet of brown sandstone 

 shales, clayey iron-stone, or siderite (in which the fossil impres- 

 sions are chiefly found), coal, &c. In ascending order they were 

 as follows : — 



a. Splintery shales, 12 feet ; h. Bed of coal, 2 feet ; c. Hard 

 shales intermixed with gritty sandstone, much obscured by debris ; 

 d. White gritty sandstone; e. 2 feet of the sideritic shale — the 

 same as the fossil leaves are found in ; out of reach ; f. Irregular 

 shales, 10 feet ; g. About 20 feet of irregular shales with irregu- 

 lar layers of coal ; and h. Shales, &c., with small bits of lignitic 

 coal, irregularly scattered throughout, about 10 feet. 



88. Many thin beds of sandstones and shales, thus : — 



1. A few inches of sandstone ; 2. Thin layer of shale ; 3. Thin 

 sandstone, same as 1 ; 4. 1 inch of sideritic shale, same as the 

 fossil impressions are in ; 5. Sandstone, as before, 1 inch ; 

 6. Shale, 1 inch ; 7. Sandstone, 2 inches ; 8. Shale, with pieces of 

 coal ; 9. Sandstone, thin ; 10. Thin clay ironstone, same as fossils 

 are contained in ; 11. Thin shale; 12. Sandstone, thin ; 13. Thin 

 shale ; 14. Thin seam of coal ; 15. Sandstone, 1 foot thick ; 

 16. Shales, 6 inches, with 17. A broken thin layer of coal in the
