Sida 294 - These are the generations of the heavens and of the earth when they were created in the day that the LORD God made the earth and the heavens...
Sida 166 - ... now unknown upon the surface of the earth, presented to his senses almost in the beauty and vigour of their primeval life ; their scaly stems, and bending branches, with their delicate apparatus of foliage, are all spread forth before him, little impaired by the lapse of countless ages, and bearing faithful records of extinct systems of vegetation, which began and terminated in times of which these relics are the infallible historians.

Sida 166 - The effect is heightened by the contrast of the coal-black colour of these vegetables, with the light ground-work of the rock to which they are attached. The spectator feels himself transported, as if by enchantment, into the forests of another world ; he beholds Trees, of forms and characters now unknown upon the surface of the earth, presented to his senses almost in the beauty and vigour of their primeval life...
Sida i - geology, in the magnitude and sublimity of the objects of which it treats, undoubtedly ranks, in the scale of the sciences, next to astronomy...
Sida 36 - ... the quantity of heat discharged over the Atlantic from "the waters of the Gulf Stream in a winter's day would be sufficient to raise the whole column of atmosphere that rests upon France and the British Islands from the freezing point to summer heat.
