in the Vicinity of Lyme Regis, Dorset, and Beer, Devon. 115 



Having thus described the chalk and the sands beneath it, as they occur 

 between Lyme Regis and Axmouth, I shall now proceed to notice the same 

 rocks as they are exhibited in the vicinity of Beer, Devon. Ample opportu- 

 nities are afforded for studying the developement of the chalky &c. at the latter 

 place, in the cliffs on both sides the village. In order, however, to understand 

 the changes which the various portions undergo, it will be necessary to com- 

 mence with the section afforded by White Cliff, between Beer and Seaton. 

 (PI. XVI. fig. 2.) 



Chalk of White Cliff, Beer. 



This rock is developed much in the same way as in the vicinity of Lyme 

 Regis, with the exception that the lowest part of the Chalk without jlints does 

 not become studded with quartz-grains, though the compact bed, abounding 

 in organic remains^ is still seen beneath it. The latter is from its hardness 

 very conspicuous, and may be seen at low water, forming a ledge of rocks that 

 extend into the sea to the eastward of the village, making a basin-shaped 

 curve, and again rising towards the line of cliffs that extend to Beer Head. 

 Near the village this bed is not so thick as in the vicinity of Lyme Regis. 



Sands and Sandstones beneath the Chalk at White Cliff. 



A glance at the sections (PI. XVI, fig. Sand 3.) will show, that though the 

 general mode of occurrence of these rocks is the same as that in the vicinity 

 of Lyme Regis, yet there are parts which at other places are more or less 

 developed. Commencing immediately beneath the compact and siliceous bed 

 above noticed, we have the upper portion of the sandstone with chert-seams 

 much thicker than at Pinhay, Whitelands, &c. At the latter place it was of 

 no great importance ; but here it has swollen out, and forms a much more 

 conspicuous part of the section, containing at the same time more green-earth. 

 The following is a section (PI. XVI. fig. 2, 3.) of this rock and of the yellow- 

 ish-brown sandstone with chert-seams, into which it passes. 



1. Yellowish-white sandstone. 



2. Nodules of compact light-coloured sandstone, connected together by 



sandstone containing green-earth. 



3. Yellowish-brown sandstone containing chert-seams. 



4. Yellowish sandstone with some green-earth, and numerous quartz- 



grains. 



5. Nodules of chert in yellowish-brown sandstone.
