PREFACE TO THE SEVENTH
EDITION
The steady advance of clinical neurology has again
necessitated a thorough revision of this book.
Numerous additions and alterations have been made
—
some chapters partly re-written. A number of new
illustrations have been introduced, chiefly in the chapter
on ventriculography and encephalography, in accordance
with the increasing importance of these diagnostic
methods. (At present it needs emphasizing, however,
that these methods should be regarded as supplementary
methods only.) A short description of angiography
has been included. A brief outline of the examination
of unconscious patients has also been added. The
additional X-ray pictures have all been reproduced from
the negative films. As the older X-ray pictures,
reproduced from the positives, have been retained, this
entails a lack of uniformity, which, however, may be
useful to the beginner, who should become familiar both
with the positive and negative films. In deciding
what to include and what to omit I have been guided
by the experience gained in the daily work in my clinic*
With three exceptions all the photos reproduced in
this book are from cases observed in my clinic, and all
the X-ray photos are taken by the X-ray department of
the hospital. I take the opportunity of thanking that
department, and its leader Professor Dale, for valuable
assistance at all times. I am also indebted to my senior
assistant, Dr. Torkildsen, for valuable help and for permission to reproduce two of his diagrams illustrating
ventriculographic interpretation. Dr. Torkildsen has
also, during the last years, done all the neurosurgery
of my clinic. I also wish to thank Dr. A.
Gurney Yates, of Sheffield, for permission to use two
excellent photos, which appear as Figs. 31 and 32 (the
only photos in this book not taken from my own
collection). I am indebted to Professor J. C. McKinley
for permission to reproduce his Motor Function Chart.
Further, my thanks are due to Dr. Forsberg (in charge
of the clinic's O.P. department) for assistance rendered;
and, finally, I wish to thank my former senior assistant,
Dr. Lossius, for his kind help in correcting the proofs for
this as well as for the previous editions.
An increase in size has been unavoidable. But it
has been my aim to keep the book within reasonable
limits. For this reason also the Foreword by my
friend and former teacher, Dr. T. Grainger Stewart,
has been left out in the present edition. I take this
opportunity to thank him both for his kindness in
writing that generous introduction, which as Foreword
has accompanied all previous editions, and also for all
his kindness to me during that remote time when, as a
budding neurologist, I served my first apprenticeship at
the National Hospital of Queen Square.
Last but not least I want to express my appreciation
of the unfailing helpfulness of the publishers.
