This is the second Geologists’ Association guide by Professor John Cope. The other is the second edition of his excellent Dorset guide. And, on the grounds that “if it ain’t broken, don’t mend it”, this guide to the south Devon coast follows the highly successful basic plan of that other guide, including the extensive use of colour photos and diagrams.

The Geologists’ Association have extended their excellent series of geological guides by producing what some people (including me) would think at first was a slightly self-indulgent couple of volumes on ‘Devonshire Marbles’. However, for my part, I soon realised that this view is entirely wrong.
