ACKNOWLEDGEMENTS

The completion of this book would not have been possible without the support of all the members of our respective families, including Richard, Polly, Charlie. William, Nico. Evelyn. Ken. Sebastian, Elizabeth and Rodolfo, who put up with starvation and neglect, obsession with hitting deadlines, and our grumpiness!

We would also like to thank the many colleagues who have lent us material, in particular Neil Forbes. Greg Simpson and Mike Daly for the loan of some very useful books. Finally, we are grateful to Mary Seager and Barbara Cooper for their faith that we could write this book and to Catharine Steers and Gail Wright at Elsevier, who are always willing to sympathise and rearrange dates when life interferes with the grand plan.
