 Ulverscroft Mill, Markfield, Bardon, and High Towers, a second ; 

 the coarse ash-beds of Benscliff, Chitterinan Hill, Timberwood Hill, 

 and the Monastery, a third ; and the quartzose rocks of Charley- 

 Wood, Charley, the Old Keservoir, and Blackbrook, a fourth. 



Hence they showed that the beds are considerably dislocated near 

 the Syenites, which removes the main objection which previous 

 writers have urged against these being intrusive ; and they described 

 the evidence they have obtained as to this being their real nature. 

 This evidence included the description of actual contacts of igneous 

 and sedimentary rock seen at two points in the wood south of 

 Bradgate House, and at a third in Bradgate Park. 



They propose, in a continuation of the paper, to touch upon the 

 Faults, and to describe in greater detail the microscopic structure of 

 the rocks.

THE NOEPOLK FOEEST BED. 



Sir, — At your request, I gladly furnish you with all the informa- 

 tion I can respecting the stools of trees being found, in situ, where 

 they grew in the Forest-bed on the eastern coast. I have repeatedly 

 seen them at Happisburgh, and once in the company of Professor 

 Sedgwick and of Professor Harry Seeley, who, at a meeting of the 

 Geological Society in 1876, gave a vivid description of the appear- 

 ance of the stools of trees, and of the gratification which Professor 

 Sedgwick expressed on seeing them. 



1 have also seen them, in situ, at Bacton, on a recent excursion of 

 several of the members of the Norwich Geological Society, by whom 

 one stool in particular, which grew out of the blue clay of the soil 

 of the forest, was examined, and ascertained to be rooted in its 

 native soil. 



On the excursion to Cromer of the members of the British Asso- 

 ciation in 1868, the company assembled on the beach at Overstrand, 

 at the spot where the stool of a tree stood on the soil of the forest. 

 Being invited, I endeavoured to explain that the trees grew on the 

 estuarine soil, in which the bones of the Eleplias meridionalis were 

 associated with Cetacean remains, after it was raised, above the 

 surface; and that then the growth of the forest commenced, of which 

 the Eleplias antiquus was the typical mammal. This stool was dug 

 up by the direction of Lady Buxton, who placed it, where it now is, 

 in the Norwich Museum. Mr. Eeeve, the Curator, says that one of 

 the roots was about four feet long, and he was obliged to have it 

 shortened to get it into its case. 



The above mentioned are the principal places where remnants of 

 the Forest-bed have survived its general destruction and denudation 

 from Kessin gland in Suffolk to Runton in Norfolk beyond Cromer. 

 The trees were torn up, and together with fossil remains were re- 

 deposited in the laminated beds above; and hence it is, no doubt, 

 that so few of the trees, or rather of the roots and stumps, are to be 

 seen at present in situ, in proportion to the debris. The evidence,
