My share in this book has been the writing of the brief introductory
Memoir, with the exception of the pages relating to Regent Square and
Willesden. These have been contributed by Mr. A. N. Macnicoll, who has
also given me the benefit of his advice throughout. I have also to
acknowledge the kindness of Principal Dykes, who has read the proofs,
and of the friends who have, amid pressing engagements, enriched the
volume with their reminiscences. The many correspondents who sent help
of various kinds are warmly thanked. There was abundant material for a
larger biography, and some of it will be utilised in another way. But it
was thought desirable that the memorial volume should be issued at a
moderate price, and that it should, so far as possible, consist of
Professor Elmslie's own work.
