I WISH to thank the Librarian and staff of the National
Library of Scotland, of Edinburgh University Library,
and of Edinburgh Central Library (especially its Reference
Division).

I must also express my gratitude to Professor Bonnie S.
McDougall for her invaluable judgement and information
respecting Chinese pottery as discussed in ' The Illustrious
Client', to Professor David Whitteridge, FRS, FRSE, for
very helpful biographical detail on the career of William
Rutherford which threw some light on the antecedents of
' The Creeping Man', to Professor Rosalind Mitchison, and
to Professor Christopher Ricks.

My debt to Hugh Robson for his pains in preparing this
work for the press is very difficult to express with a suffi-
ciency of thanks. My debt to Anne Robson can never
receive sufficient acknowledgement.

WWR
