innorainatum, left femur, tibia, fibula, calcaneum, cuboid, iv meta- 

 tarsal, right fibula, calcaneum, cuboid, iv metatarsal, astragalus, 

 left luuare and scaphoid, and portions of ribs of a Hippopotamus, 

 also part of the breast-bone of an Elephas, and part of the tibia of 

 a Rhinoceros. The Hippopotamus-hones were well preserved, and 

 probably belonged to one animal. The body was most likely 

 stranded in an old channel of the Biver Derwent, and quickly 

 covered up with sand and clay, but not before the bones were some- 

 what disturbed. They were found in a dark-coloured sand above 

 the river-gravel, at a depth of 9 feet 8 inches below the surface. 



Mr. Clement Eeid found some twenty or more species of plant- 

 remains in the sand. These plants "indicate a moist meadow or 

 swampy ground, and a temperate climate. The species are all 

 widely distributed." 



Part II. By E. M. Deeley, Esq., F.G.S. 



The deposits in which the bones were found occupy a wide trench 

 which occurs on the inside edge of a gravel-terrace stretching for 

 several miles south of Derby, at a height of 15 or 20 feet above 

 the modern alluvial plain. The gravels are of later age than the 

 Great Chalky Boulder-clay, and were formed at a time when the 

 rivers were removing from their pre-Glacial valleys the older 

 Boulder-clays, with which they had been partially filled. Gravels 

 of two ages are recognized : (a) recent gravels well stratified, 

 undisturbed, and covered in many places by a thick layer of brick- 

 earth ; and (6) high-level gravels showing " trail " and contorted 

 bedding. It is in these latter gravels that the trench containing 

 the mammalian remains occurs. The deposits occupying this old 

 waterway and the contorted high-level gravels are placed together 

 in the same period ; and the author gives reasons for supposing that 

 they are both of Interglacial age. the contortions and surface- 

 disturbances having been produced during a recent cold period, 

 most probably by a lobe of ice which passed down the Trent Valley. 

 Several peculiar physical features of the valleys, such as the flowing 

 surface-outlines of the higher gravel-terraces, and the occurrence of 

 lacustrine deposits in the low-level area occupied by Sinfin Moor, 

 are instanced as supporting this view.

 the Chair. The following communications were read : — 



1. " An Account of a Head or Gateway driven into the Eastern 

 Boundary-fault of the South Staffordshire Coal-field." By William 

 Farnworth, Esq., F.G.S. 



The author describes certain peculiarities observed during the 

 driving of a head towards the fault separating the Coal-measures 

 and Permian rocks, from a pit situated four miles east of Walsall, 

 at the southern extremity of the Cannock Chase Coal-field. 



2. " Dundry Hill : its Upper Portion, or the Beds marked as 

 Inferior Oolite (G 5) in the Maps of the Geological Survey." By
