158 Rev. A. Sedgwick and Mr. Murchison on Deposits contained between 



for the most part, to be classed with the old red sandstone of England, — that 

 the new red sandstone, with a few limited exceptions, has no representative, — 

 and that the rocks of the carboniferous order either do not appear at all, or 

 conform to so new a type as to leave no hope for the discovery of those 

 beds of coal which characterize the formations of the same age in the south 

 part of the island. 



Table, in descending order, of the Secondary Formations in the North of 

 Scotland and the Western Isles. 



Formations. 



1. Chalk. Flints containing many fossils of this 



formation. (Geol. Trans. Second Series, 

 vol. ii. Part III. p. 365.) 



2. Blue clay and shale, containing fresh-water 



fossils of the Weald clay and Hastings sand. 

 (Geol. Trans. Second Series, vol. ii. Part 

 III. p. 366.) 



3. Grit of the Coral-rag (calcareous grit of 



England. (Geol. Trans. Second Series, 

 vol. ii. Part II. p. 318.) 



4. Shale beds, &c. with fossils of the Oxford 



clay. (Geol. Trans. Second Series, vol. ii. 

 Part. II. p. 319.) 



5. Upper beds of the Great Oolite, resembling 



Cornbrash and Forest marble, and with 

 characteristic fossils. (Geol. Trans. Second 

 Series, vol. ii. Part. II. p. 321. Part. III. 

 p. 367.) 



6. Great formation (occupying the place of the 



Great and Inferior Oolite) ; the upper part 

 composed of sand and sandstone ; the lower 

 part of carboniferous shales and sandstones, 

 with many organic remains. (Geol, Trans. 

 Second Series, vol. ii. Part II. p. 320, &c. 

 Part III. p. 360, &c.) 



7. Lias. The upper part composed of mica. 



ceous shales graduating into the superior 

 formation ; the lower part of blue lime- 

 stone. The whole group charged with 

 Gryphites, Belemnites, &c. &c. (Geol. 

 Trans, iit supra.), 



Localities. 

 Plains of Aberdeenshire west of Peterhead, 



Loch Staffin, Isle of Skye. 



Braambury Hill, Brora, &c. 



Dunrobin coast. Brora. 



East coast of Trotternish, Skye ; Beal, near 

 Portree, Skye; Scrapidale, Rasay. 



The sand and sandstone on the east coasts of 

 Trotternish and Rasay ; Carsaig, south coast 

 of Mull ; Strathsteven, Brora, &c. — The in- 

 ferior carboniferous shales and sandstones ; 

 Brora coal-pits; cliffs opposite Portree, Skye; 

 Holme water-fall, Skye ; South coast of Mull. 



Upper part; base of cliff. Holme, Skye ; Scalpa; 

 Pabba ; Carsaig and Tobermory, &c. Mull ; 

 Coast north and south of Cromarty Sutors ; 

 lower limestone ; Broadford, Skye, Apple- 

 cross ; coasts of Morven. — N.B. At Strath 

 in Skye the whole formation near the Syenite 

 is white and crystalline. (See MacCulloch, 

 West. Islands, vol. i. p. 352.)
