viii PREFACE TO THE EIGHTH EDITION
Yorston of the Department of Otolaryngology in Dundee. Some n$w radio-
graphs have been supplied by Professor Eric Samuel and his colleagues, and
some of the contributors have included original illustrations. In order to
save production costs the colour illustrations have been printed together,
and both authors and publishers realize the frustration that this imposes on
the readers and hope for their tolerance.
It is a very real pleasure to record once again our appreciation of the
courtesy and co-operation which we have received from the publishers.
