at the start oa the Old Moor I should put it at 15 or 20 feet of 

 clay, but it thickens in a south-west direction, and at Cop Eound 

 I estimate it to be 60 to 80 feet thick, which thickness it maintains 

 up to the Moss Rake. After that it seems to thin out ; but just 

 above The Holmes and beneath the Eoman Camp it craps out 

 strongly again and is about 80 feet thick, if not more. From The 

 Holmes to Bushy Heath I could not ascertain the thickness. At 

 Cop Eound some blocks are concretionary, and I have not noticed 

 any columnar structure. The bed seems to decompose into clay 

 very freely where it is not thick. 



I wish to draw attention to this bed of Toadstone because I think 

 it will be of importance in the stratigraphy of the Toadstone beds 

 near Tideswell, Litton, and Wheston ; and further, in order that the 

 bed may not be overlooked in any future resurvey of the country : 

 it is not a prominent bed like the one immediately below it. 



With regard to this latter bed I may as well point out what 

 strikes me as an error on the part of the Geological Survey. On their 

 1" map 81 N.E. the bed is made to start at a point between Eldon 

 Hole (IX S.E.) and the summit of Eldon Hill, at 1,480 feet 

 altitude, where the limestone beds dip true E. 40° S., at an angle 

 of 6° ; it is then drawn to run down into Cunningsdale, round 

 Oxlow, across Oxlow Eake to Oxlow Dam, and on to The Cop 

 Farmhouse. In the length between Eldon Hill and Oxlow Dam 

 I cannot find any evidence of an outcrop of Toadstone, or even of 

 clay that might be decomposed Toadstone. As one traces the bed west- 

 ward from The Cop Farmhouse (IX S.E.) it appears to thin out, and, 

 vanish at a spring just outside the south-west corner of Starvehouse 

 Mine. Moreover, the line as drawn in its descent from Watts 

 Plantation (IX S.E.) to the bottom of Cunningsdale, and in its ascent 

 again to Oxlow Eake, does not follow the dip, but cuts across the 

 limestone beds in a manner not usual with the Toadstone in this 

 part of the country.

AGAIN it is our pleasant task to welcome the issue of another 

 volume (larger than usual) of this Society's admirable 

 publications, which has for its object the description and figuring 

 of all the known British fossils. 



When its heroic founders set out on this enterprising task, nearly 

 sixty years ago, they were doubtless as courageous as Jason and 

 his Argonauts when they set sail in the good ship Argo to fetch 

 the golden fleece ; but, like Jason and his Grecian heroes, they 

 must soon have found that they had undertaken a very arduous
