many j but to the south its extent is veiy small, for as the oolites 

 thicken towards Lincolnshire, the sandstone and shale are attenuated. 



" Having thus noticed, in general terms," Mr. Phillips observes, 

 " the characters of the carboniferous and oolitic formation, it remains 

 to state, that of this whole series, which measures, in some places, not 

 less than seven hundred feet in thickness, no part whatever is conti- 

 nued across the H umber, except the calcareous strata. Indeed, I am 

 in doubt whether any portion of the sandstones, shales, and coal, is 

 prolonged to the south so far as the river Derwent." 



" If we were to put out of consideration the shelly beds of lime- 

 stone, which alternate with them, we should find in these carbonife- 

 rous rocks much resemblance to that more ancient deposit of coal, 

 and sandstone, and shale, which has been expressly called the coal 

 formation. But still we are furnished with the most satisfactory 

 means of discrimination, in the plants which accompany the coal: for 

 though, perhaps, one hundred species of fossil plants have been dis- 

 covered in the west-riding coal-field, and not less than fifty in the 

 sandstones and shales of the north-eastern coast j it is not too bold 

 an assertion to affirm, that no one species has yet been found which 

 is common to both situations. 



"The Tabular Oolitic Hills. 



" These hills meet the sea-coast between Filey and Scarborough 

 on the east. They rise toward the north from under the vale of 

 Pickering, and terminate in a remarkable line of escarpments at 

 Silpho Brow, Blakehoe Topping, Saltergate, Lestingham, Easterside, 

 and Black Hambleton. From the vale of Pickering the ascent to 

 them is long and gradual, but from the northern moors it is very short 

 and abrupt. The altitude of the hills increases westward. Thus, 

 Gristhorpe cliffs are about two hundred and seventy feet high ; Oli- 

 ver's mount, four hundred and ninety feet ; the heights above Trout- 

 beck, six hundred and fifty feet ; above Rievaulx Abbey, eight hun- 

 dred feet; and at Hambleton, twelve hundred and forty-six feet. 

 Even at considerable distances, the plane summits and abrupt termi- 

 nations of these oolitic hills are very remarkable."

The upper calcareous grit was first noticed and described by Mr. 

 Phillips in his paper in the Phil. Mag. and Annals for April 1828.
