Side 336 - I would refer those who may be anxious to know the last word on this much-debated question. The evidence of interglacial conditions within the Alpine lands continues to increase. These are represented by alluvial deposits of silt, sand, gravel, conglomerate, breccia, and lignites. Penck, Bohm, and Bruckner find evidence of two interglacial epochs, and maintain that there have been three distinct and separate epochs of glaciation in the Alps.
Side 417 - pro-mammalian " group, and not by any of the known forms of Sauropsida ; and there is other evidence which tends in the same direction. Thus, the Amphibia are the only air-breathing Vertebrata, which. like Mammals, have a dicondylian skull. It is only in them that the articular element of the mandibular arch remains cartilaginous; while the quadrate ossification is small, and the squamosal extends down over it to the osseous elements of the mandible ; thus affording an easy transition to the mammalian...
Side 45 - A large proportion of the stones had been drilled through and through hy the action of the current upon small pebbles lodged in hollows or between the joints of the stone ; and the author estimates that as a result of 43 years of erosion, six of the stones of the apron, which may be taken as a sample, had lost the following amounts respectively :— 45, 60, 48, 50, 37, and 58 per cent. 2.

Side 45 - River, running iu a north-easterly direction along a subsidiary anticline from near Jasper for a distance of sixty miles. From the base of the Cambrian beds, the whole Lower and Upper Palaeozoic formations succeed each other in apparently conformable sequence, except at the junction of the Upper and Lower Silurian series, where a probable discordance occurs. The prolonged period of subsidence and deposition at length gave way to elevation ; acting with the greatest effect along the Alleghanies. Under...
