The authors and publishers are grateful to the Director, Dr G F Claringbull, for permission to photograph the specimens. Many of our colleagues have helped us by reading and correcting the manuscript, and by making suggestions for its improvement. In particular we should like to thank Miss Valerie Jones, who has drawn most of the diagrams illustrating the sections on minerals and rocks. We are grateful to our editor, Ian Jackson, whose care and patience during the progress of the work made our task so much easier. AC Bishop, ARWoolley (minerals and rocks) and WR Hamilton (fossils) The size of the specimens shown In the photographs is indicated by a rule which is positioned, wherever possible, at the foot of each plate. The length of the rule varies from page to page, depending on the scale of the specimens on each plate (the longer the rule, the smaller the specimens), but it always represents 5cm and therefore allows quick comparison of the sizes of specimens from anywhere in the book. The photographs in this book were taken by Peter J Green/lmitor and the line drawings prepared by Valerie Jones and Oxford Illustrators Limited.
