An Introduction to Geology

Originally published in 1905, this book provides an introductory guide to the 'scope and methods' of geology. Marr uses simple language to describe geological phenomena such as earthquakes and the erosive effects of the wind, sea, glaciers and rivers. The text is illustrated with diagrams and photographs demonstrating many of the topics discussed, including fossils and geological strata. This book will be of value to anyone with an interest in the history of science education in Britain.
