Page 23 - Irish elks, roe deer, wild oxen, and bisons roamed over the plains ; wild boars, three kinds of rhinoceros, two kinds of elephant, brown bears and grizzly bears, haunted the forests. The rivers were tenanted by the hippopotamus, beaver, otter, waterrat ; while among the carnivora were wolves, foxes, wild cats, hyaenas, and lions. Many of these animals must have moved in herds across the plains, over which the North Sea now rolls. Their bones have been dredged up in hundreds by the fishermen from...
Page 242 - At times when the wind is from some Easterly point, the Helm forms over this district ; the chief features of the phenomenon being the following. A heavy bank of cloud rests along the Cross Fell range...
Page 27 - Ireland number 970 — about twothirds of the British flora. Such facts as these are not explicable by any difference of climate rendering Ireland less fit for the reception of more varied vegetation and animal life ; for the climate of Ireland is really more equable and genial than that of the regions lying to the east of it. They receive a natural and consistent interpretation on the assumption of the gradual separation of the British Islands during a continuous north-westward migration of the...
Page 25 - Britain can have had a more powerful influence on its human history than the separation of the country as a group of islands cut off by a considerable channel from direct communication with the mainland of Europe. Let us consider for a moment how the disconnection was probably brought about. There can be no doubt that at the time when Britain became an island, the general contour of the country was, on the whole, what it is still. The same groups of mountains rose above the same plains and valleys,...
Page 192 - The THIRD division — forming only inferior elevations — commences with a bed of dark-blue or blackish transition limestone, containing here and there a few shells and madrepores, and alternating with a slaty rock of the same colour; the different layers of each being in some places several feet, in others only a few inches in thickness. This limestone crosses the river Duddon near Broughton; passing Broughton Mills it runs in a north-east direction through Torver, by the foot of the Old Man mountain,...
Page 23 - Its glaciers, frozen rivers and lakes, and floating icebergs, had converted most of Britain, and the whole of Northern Europe, into a waste of ice and snow, such as North Greenland still is; but the height of the cold was past, and there now came intervals of milder seasons, when the wintry mantle was withdrawn northward, so as to allow the vegetation and the roaming animals of more temperate latitudes to spread westward into Britain. From time to time a renewal of the cold once more sent down the...
Page 67 - For a while, till it sleeps In its own little lake. And thence at departing, Awakening and starting, It runs through the reeds, And away it proceeds, Through meadow and glade, In sun and in shade, And through the wood-shelter, Among crags in its flurry, Helter-skelter, Hurry-skurry.
Page 159 - ... modified on the eastern side, by the elevation of a long and wide range of high ground, extending from what is now the vale of the Tyne, to the sources of the Aire and the Ribble; and the sea which had flowed without interruption around, was bounded by the lofty isthmus of Howgill Fell and Wildboar Fell ; and rejected, far to the south, by a general rising on the whole of the south-eastern margin of the district. 2. The relative elevations of land in and around the Lake district, which we behold...
Page 26 - ... march in that direction was arrested, and before the subsequent advancing bands had come as far as Britain, it too had been separated by a sea channel which finally barred their progress. Comparing the total land mammals of the west of Europe, we find that while Germany has ninety species, Britain has forty, and Ireland only twenty-two. The reptiles and amphibia of Germany number twenty-two, those of Britain thirteen, and those of Ireland four. Again, even among the winged tribes, where the capacity...
Page 324 - ... that each specific disease is due to the influence of a distinct morbid substance on some part or parts at which the characteristic signs of the disease can be and are manifested. Two conditions must coincide in each : the one general or diffused in morbid material in the blood ; the other local, in some part with which this material produces disease.
