Morte Slates and Associated Beds in North Devon. 521 



the base of the Spilsby Sandstone is stated to be very doubtful 

 and the fossils of the so-called ' pebbles ' are considered as probably 

 representing an original fauna, poorly preserved in nodules formed 

 during a temporary pause in the sedimentation. 



The ' Zone of Bel. lateralis ' (Serie Speetono-russe of Pavlow) is 

 shown to bridge over the space between undoubtedly Jurassic and 

 undoubtedly Lower Cretaceous strata ; but according to the recent 

 results of Prof. A. Pavlow, if the accepted classification of other 

 areas is to be upheld, the division between the two systems must be 

 placed high enough to include this zone in the Jurassic, in spite of 

 the local inconvenience of this arrangement.

The ' mid-Glacial ' sands of the cliffs between Yarmouth and 

 Lowestoft are overlain at Corton by Chalky Boulder Clay. But 

 farther north than Corton some masses of the same clay occur in 

 the interior of the cliffs, surrounded by the sands in undisturbed 

 stratification, but passing into them by strings and patches such as 

 suggest the melting off of enveloping ice. They have probably 

 been floated and dropped there. 



Again, gravels lying in a valley of Chalky Boulder Clay in West 

 Suffolk (Cockfield &c), and indicating considerable denudation of 

 the Clay, yet have some patches and sheets of that Clay overlying 

 them as if carried down or slipped down from higher ground. 



This may explain some anomalous positions of Boulder Clay 

 noted by writers. The Lowestoft observations suggest that Chalky 

 Boulder Clay was being manufactured in one locality simultaneously 

 with ' mid-Glacial ' sands in another.

1. ' On the Morte Slates and Associated Beds in North Devon and 

 West Somerset.— Part I.' By Henry Hicks, M.D., F.R.S., F.G.S. 



In a paper read before the Society in 1890 the author stated that 

 he had found the Morte Slates to be fossiliferous, and had come to 

 the conclusion that they were the oldest rocks in the North Devon 

 area and had been thrust over much newer rocks, producing a 

 deceptive appearance of conformity ; and that there was not a con- 

 tinuous upward succession in the rocks from the Bristol Channel to 

 the neighbourhood of Barnstaple. Since that paper was read, the
