Book excerpt: The Geological Society has much to be proud of in its two hundred years of history. Not only is it the oldest society of its kind in the world, but it has also seen many of the important developments in the science played out within its premises. Gordon Herries Davies has expertly and entertainingly laid out this narrative for us, steering a skilful course between the necessary facts and the anecdotes that bring these facts alive. Institutional histories can be dull affairs - a litany of minutes and memoranda - but this history suffers from no such problem. This book will appeal to the historian of science, geoscientists in all branches of the subject and anyone with an interest in the development of scientific ideas in the nineteenth and twentieth centuries.
