The primary mucus (that in which electricity originates life) was, and is still, generated in those very parts of the sea where the water is in contact with earth and air, and thus upon the shores. The first creation of the organic took place where the first mountain summits projected out of the water, — indeed, without doubt,...

The reasoning brain would have been wholly at fault in a scene of things in which it could neither foresee the exterminating calamity while yet distant, nor control it when it had come ; and so the reasoning brain was not produced until the scene had undergone a slow but thorough process of change, during which, at each progressive stage, it had furnished a platform for higher and still higher life.

Fishes and reptiles were the proper inhabitants of our planet during the ages of the earth-tempests ; and when, under the operation of the chemical laws, these had become less frequent and terrible, the higher mammals were introduced. That prolonged ages of these tempests did exist, and that they gradually settled down, until the state of things became at length comparatively fixed and stable, few geologists will be disposed to deny. The evidence which supports this special theory of the...

The necessity for a simpler cause is obvious, and it is found in the hypothesis of a spread of terrestrial vegetation from the sea into the lands adjacent. The community of forms in the various regions opposed to each other, merely indicates a distinct marine creation in each of the oceanic areas respectively interposed, and which would naturally advance into the lands nearest to it, as far as circumstances of soil and climate were found...

729 페이지 - What could man have done on the globe at a time when such outbursts were comparatively common occurrences ? What could he have done where Edinburgh now stands during that overflow of trap porphyry of which the Pentland range forms but a fragment, or that outburst of greenstone of which but a portion remains in the dark ponderous coping of Salisbury Craigs, or when the thick floor of rock on which the city stands was broken up, like the ice of an arctic sea during a tempest in spring, and laid on...
608 페이지 - It was also valuable as being a powerful absorbent, as it would absorb about 80 per cent, of water, and keep it for the benefit of the soil which might surround it, while it took up the greater portion of the obnoxious gases inherent in night-soil and sewage matter, and thereby did away with any bad effect which might result from them. It therefore was capable of being converted into a manure of the greatest value, the proportions being two-thirds of night-soil to onethird of charcoal. It was impossible...
