Excerpt from On the Structure and Affinities of the Tabulate Corals of the Palaeozoic Period: With Critical DescriptionsThe material upon which this work is based is principally, though not exclusively, contained in the extensive collections of Corals which I have made from the Palaeozoic formations of Britain, the Continent of Europe, and North America; but I have also had the Opportunity of consulting the collections of the British Museum, the Museum of Practical Geology, and the Edinburgh Museum of Science and Art. The method of investigation which I have adopted has been largely that of microscopic sections, and the present work is, therefore, much more extensively occupied with detailed descriptions of minute structure than has been usual in treatises or memoirs dealing with the fossil Corals. For the same reason I have been more concerned to investigate the actual anatomy and systematic relations of even perfectly well known types, than to describe new forms or to discuss difficult and disputed points of specific determination. The necessary sections, with few exceptions, have been personally prepared by myself, and the illustrations of microscopic structure are from drawings made by the camera lucida. Unless otherwise explicitly acknowledged, all the illustrations, whether in the text or the plates, are from original drawings of my own; and I have to return my best thanks to my friend Mr Berjeau for the care and fidelity with which he has reproduced these on wood and stone.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
