100 Notes made during a Visit to the 



II. Section of the Strata at Rings Quarry from below the " Dirt- 

 bed" down to the " Whit-bed." 



In the subjoined strata, which exhibit few of the marks of violence so 

 striking in the beds above, vast clefts or chasms occasionally occur from 

 2 ft. to 4 ft. in width at the surface, which go down to a considerable 

 depth, gradually decreasing in size as you descend.

12. * Top cap ' At bottom of this a bed called * grizzle,' abound-

 mentioned, nor the skull-cap below, contain, 

 occasionally, but very irregularly, occurs. 

 Sometimes, however, it is entirely wanting, 

 and no organic remains are met with till we 

 reach the roach - - -40 



13. Second * dirt bed ' consists of the same black mould, with the 



same water-worn pebbles as the first ' dirt 

 bed.' It contains a great many round 

 masses of petrified wood, called by the 

 quarrymen * petrified crows' nests, ' 

 which, in shape and contour, they cer- 

 tainly somewhat resemble; but which 

 Dr. Buckland, with much greater proba- 

 bility, considers to be the fruit of the trees 

 aforementioned, which he has denomi- 

 nated Cycadoideae, and on which he has 

 published a long and interesting disserta- 

 tion in the 2d volume of the 2d series 

 of the Transactions of the Geological So- 

 ciety of London -

Nos. 11. and 12. " Top cap" and " rising cap," although 

 destitute of shells or other organic remains, are burnt for lime, 

 and are in high repute amongst the agriculturists of Dorset- 

 shire for that purpose. 



No. 16. The " roach " contains an immense quantity of 

 testaceous remains, being in some places a complete aggregate 

 of fossil marine shells ; it forms, however, — so at least the 

 quarrymen assured me, — a good building stone, very durable 

 and impervious to the rains and frost. None of the other beds, 

 save, as already stated, the " grizzle," occasionally found 

 under the " top cap," contain any organic remains.
