104 페이지 - ... and human objects, was agglutinated to the roof by the infiltration of water holding lime in solution ; that subsequently, and within the human period, such a great amount of change took place in the physical configuration of the district as to have caused the cave to be washed out and emptied of its contents, excepting the floor breccia, and the patches of material cemented to the roof and since coated with additional stalagmite.
197 페이지 - River. The coal is a soft black lignite, of a dull earthy fracture, interspersed with small lenticular bands of bright crystalline coal, and resembles some of the duller varieties of coal produced in the South Derbyshire and other central coalfields in England.
459 페이지 - The proofs that this is the true mode of the generation of the asphalt repose not only on the partial manner in which it is distributed in the strata, but also on numerous specimens of the vegetable matter in process of transformation, and with the organic structure more or less obliterated. After the removal by solution of the bituminous material under the microscope, a remarkable alteration and corrosion of the vegetable cells becomes apparent, which is not presented in any other form of the mineralization...
103 페이지 - The wreck of these ejecta was visible in the patches of ' ceneri impastati,' containing fossil bones, below the mouth of the cavern. That a long period must have operated in the extinction of the hysona, cave-lion, and other fossil species, is certain, but no index remains for its measurement. The author would call the careful attention of cautious geologists to the inferences — that the Maccagnone Cave was filled up to the roof within the human period, so that a thick layer of bone -splinters,...

His conclusion is thus stated by himself : — " If, therefore, the presence of worked flints in the diluvial banks of the Somme, long since brought to light by M.

479 페이지 - ER Wood, FGS, the latter of whom has carefully explored at his own charge, since 1848, some of the caves previously known, as well as several discovered by himself. The known bone-caves of Gower (of which Paviland, Spritsail Tor, and Bacon Hole have already supplied Dr. Buckland and others to some extent with materials for the history of the Cave-period) are in the Carboniferous Limestone ; and, with the exception of that of Spritsail Tor, which is on the west coast of the peninsula, they all occur...
188 페이지 - It was found lying at the depth of sixteen feet from the upper surface, and about eighteen inches from the face or outer surface of the quarry, to which extent the gravel had been removed by me before I found- it. The bed of gravel in question forms the capping or summit of a slight elevation of the chalk. A section of this pit, which Mr. Prestwich lately exhibited to the Royal Society*, showed that the gravel presents here a thickness of about ten feet. Above this occurs a thin bed of coarse, white,...
