Ward, J. C. The Origin of some Lake Basins of Cumberland. Quart. 

 Journ. Geol. Soc. vol. xxx. pp. 96-102, plates (map and sections). 



Details of the soundings of the lakes are given ; and when the re- 

 sults are drawn to scale it is seen that the lakes lie in rock-basins 

 of quite insignificant size as compared with the surrounding ground. 

 The valleys of the district are of ancient date, carved out by the 

 weather and running water. The lake-hoUows are of recent date ; and 

 various arguments are given to prove that they must have been exca- 

 vated by glaciers. The lakes have been excavated in the comparatively 

 soft Skiddaw Slates ; they correspond in direction with that of the ice- 

 markings in the neighbourhood ; the deepest parts of the lakes are at 

 the confluence of old ice-streams. W. T.

Whitaker, W. On the occurrence of Thanet Beds and of Crag at 

 Sudbury, Suffolk. Quart. Journ. Geol. Soc. vol. xxx. pp. 401-405 

 (woodcut section). 



The chief section described is in a Chalk-pit at Balingdon, which 

 showed (beneath London Clay) 9 feet of Reading Beds and 14 feet of 

 Thanet Sand. The age of the beds is inferred from their similarity to 

 the Thanet Sand of S. Essex. 



The Crag is seen in pits close to the town ; it resembles the Crag of 

 other places, and is unlike any drift-bed of the district. It contains 

 phosphatic nodules, phospliatized bones, and ironstone-nodules. Four- 

 teen fossil forms have been discovered ; but the species of these cannot 

 often be determined. The Crag here seems at a higher level than else- 

 where ; it belongs to the Red Crag. W. T,
