An Introduction to Geology, and its Associate Sciences [antikvár]

THE EDITOR'S PREFACE. The distinctive character of this popular work consists in the condensed view which it gives of Mineralogy, Fossil Botany, and Palaeontology, considered in their relation to the Natural History of the Earth. Keeping the Author's original object in view, the Editor has endeavoured to render the text still more concise by excluding all irrelevant matter; and has thus gained space for considerable additions, especially to the chapters on the Tertiary, Cretaceous, Wealden, Oolitic, Liasic, Devonian and Silurian groups.The article, Palaeontology, has been entirely re-written, and the best authors on the subject carefully consulted. In this the Editor has been especially indebted to the admirable Traite Element aire de Paléontologie of Professor Pictet, Cuvier's Osseinents Eossiles, Yogt's LehrbucTi der Geologie und PetrefaetenTcunde, Groldfüss's Petrefacta Germanice, D'Orbigny's Cours Element aire de PaUontologie, and the works of our distinguished countrymen, Professors Owen and Grant, Sir C. Lyell, Sir R. Murchison, Sir H. De la Beche, Dr. Mantell, and Professor Sedgwick.A considerable number of woodcuts have been added, especially to the Palaeontology and special geology; as good figures are of great importance in imparting clear ideas on these branches of Natural Science.May, 1851.
