2. ' Discovery of Mammalian Eemains in the Old River-gravels 

 of the Derwent near Derby.' — Part I. By H. H, Arnold-Bemrose, 

 Esq., M.A., F.G.S. 



A few mammalian bones were found in sinking a well at Allenton. 

 On April 8th, 1895, the Authors commenced further excavations, 

 and were successful in finding the lower jaw, 26 vertebrte, the os 

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

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

 left lunare and scaphoid, and portions of ribs of a Bijypopotamus, 

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

 a Rhinoceros. The Hi^ppopotamus-hones. were well-preserved, and 

 probably belonged to one animal. The body was most likely 

 stranded in an old channel of the lliver 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 Reid found some twenty or more species of plant- 

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

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

 widely distributed.' 



Part II. By R. 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 preglacial 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.
