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 289 - Shall it any longer then be said, that a science, which unfolds such abundant evidence of the Being and Attributes of God, can reasonably be viewed in any other light than as the efficient Auxiliary and Handmaid of Religion ? Some few there still may be, whom timidity or prejudice or want of opportunity allow not to examine its evidence ; who are alarmed by the novelty, or surprised by the extent and magnitude of the views which Geology forces on their attention, and who would rather have kept closed...
Sida 221 - ... the Phlegraean fields of Italy or Sicily which displays in greater perfection the peculiar features of a country desolated by volcanic phenomena. It is true that the cones thrown up around are partially wooded and in general covered with herbage ; but the sides of some are still naked ; and the interior of their broken craters rugged, black, and scorified, as well as the rocky floods of lava with which they have loaded the plain, have a freshness of aspect such as the products of fire alone could...
Sida 165 - The most elaborate imitations of living foliage on the painted ceilings of Italian palaces bear no comparison with the beauteous profusion of extinct vegetable forms with which the galleries of these instructive coal mines are overhung. The roof is covered as with a canopy of gorgeous tapestry, enriched with festoons of most graceful foliage flung in wild irregular profusion over every portion of its surface.
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.
