This book contains six classic articles on the subject of structure in animal life, being a selection of essays exploring the relationship between natural history and the idea of God. Although old and largely scientifically out-dated, the information contained within these essays will be of considerable utility to those with an interest in the development of scientific thought, especially in relation to religion. Contents include: "Four Different Plans of Structure Among Animals", "Religion and Natural History", "Remote Antiquity of Animal Life as Shown in he Coral Reefs", "Physical History of the Earth.--Man the Ultimate Object", "Triple Coincidence in the Succession, Graduation, and Growth of Animals", and "Evidence of an Intelligent and Constantly Creative Mind in the Plans and Variations of Structure". Many vintage books such as this are increasingly scarce and expensive. We are republishing this volume now in an affordable, modern, high-quality edition complete with its original artwork and text. First published in 1882.
