groups of dome-sliaped rocks or rocJies moutonnees, often crossing 

 stratification and cleavage, showing smoothly-ronnded and striated 

 ■up-stream, and jagged down-stream or lee sides, and occurring at 

 both low and high levels. In the boulder-clay of the plains the 

 intensely glaciated stones (more so than I have seen or heard of in 

 any other part of the British Isles) bear witness (as I have else- 

 where endeavoured to show) to the action of floating ice. There 

 are numerous and widespread indications of the transportation of 

 boulders across mountain-ranges and drainage-areas, and to distances 

 probably not paralleled in any other part of the British Islands. In 

 some of the upland cwms and valleys there are perhaps the best 

 defined sujpr a- glacial moraines to be met with anywhere else in the 

 kingdom." This is followed by a statement of the newest opinions 

 at which the author has arrived concerning the general sequence of 

 glacial and interglacial events.^

1. '' The Bone-caves of Creswell Crags." — Second paper. By the 

 Eev. J. Magens Mello, M.A., F.G.S. 



In this paper the author gives an account of the continuation of 

 his researches upon the contents of the caves in Creswell Crags, 

 Derbyshire. The further exploration of the Pin Hole Cave described 

 in his former paper ^ furnished a few bones of Eeindeer, Rhinoceros 

 ticJiorliinus, and other animals, but no more remains of the Arctic 

 Fox, which were particularly sought for. Operations in this cave 

 were stopped because the red sand in which the bones were found 

 towards the entrance became filled with limestone fragments, and 

 almost barren of organic remains. The author then commenced the 

 examination of a chambered cave called Eobin Hood's Cave, situated 

 a little lower down the ravine on the same side. The section of the 

 contents of this cave showed a small thickness of dark surface-soil, 

 containing fragments of Eoman and Medieeval pottery, a human 

 incisor, and bones of sheep and other recent animals ; over a con- 

 siderable portion a hard limestone breccia, varying in thickness 

 from a few inches to about three feet ; beneath this a deposit of light- 

 coloured cave-earth, varying in thickness inversely to the breccia, 

 overlying a dark-red sand about three feet thick, like that of the. Pin 

 Hole, but with patches of laminated red clay near the base, and 

 containing scattered nodules of black oxide of manganese, and some 

 quartzite and other pebbles, which rested upon a bed of lighter- 

 coloured sands containing blocks of limestone, probably forming 

 part of the original floor of the cavern. The hard stalagmitic
