large cylindrical bones resembling those of Megalosaurus, but too 

 imperfect to be identified with certainty." 



The pink clays contain a great quantity of lignite, and good specimens 

 of the stems of ferns may be obtained from them. 



The junction of the Hastings sands and Purbeck beds is not visible at 

 Swanage. The line runs along the foot of the hill upon which the town 

 is built, by the church to Court farm, passing, at Herston, through a 

 small copse which is situated in the middle of a meadow, to the keeper's 

 house at the back of Leeson farm, immediately beyond which, in the 

 lane leading to Wilkeswood, the thin upper beds of the marble are 

 exposed. It follows this lane, which skirts two woods, and continues 

 along the stream to Wilkeswood farm, where the Hastings sand forms a 

 steep bank to Quarry farm, and the line of marble is marked in the valley 

 by hillocks formed of the refuse from the ancient quarries, as far as the 

 worked marble quarry at Woody Hyde ; then the line continues and 

 crosses the tunipike road at the foot of Kingston Hill. 



At the Woody Hyde Quarry, which is situated about half a mile east of 

 Kingston Hill, the beds of marble appear in the following succession, in 

 descending order : — 



feet, inches. 



1. Rag 3 



2. Paving Beds, each 6 in 1 



3. Clay 3 



4. Ceiling Bed 7 



5. Blue Marl 3 



6. Marble 1 7 



7. Blue Marl. Depth unknown below 4 feet 



The marble slabs which are noticeable in many of our churches and 

 cathedrals, frequently of a pinkish hue, and yielding to the weather, were 

 quarried from the upper beds. That which is now obtained from the 

 bed numbered 6 in the above list, is of very superior quality. Specimens 

 of the pink marble can only now be obtained lirom the old walls in the 

 valley, whence also may frequently be collected good specimens of Unio 

 from the same beds, with, occasionally, teeth and palates. Above Woody 

 Hyde, and immediately below Afflington Barn, a waggon track passes 

 over, and exposes the edges of the Purbeck beds as they run out on the 

 side of the hill. At this spot they show evidence of great disturbance. 

 This may be connected with and caused by the great fault which is ex- 

 posed in the centre of Durdleston Bay, and which runs through the Island. 

 But it will be found also that a line drawn from this spot to Peveral 

 Point, will cross Primrose Hill — where the marble appears broken and 

 forced up — and the lane at a few paces below Leeson Gate, where the 

 Corbula beds are similarly disturbed. At the Point, the comminuted 

 shell limestone, or mjarble rag, has been broken across, and turned up so as 

 to form with that portion which continues in its natural position, what is 

 geologically tunned a synclinal^ or inverted saddle, breaking up the 

 marble beds, and throwing their remains into the thus formed hollow. As 

 a proof how much the island has been disturbed, I would mention the 

 frequent occurrence of what the quarriers call jumps in the strata. As 

 they work on the vein, of a sudden the vein ends, and is found again either 

 above or below its proper level ; but after quarrying some distance further, 

 the second JMWj3 is arrived at, and then the vein continues in its proper
