PREFACE TO VOL. II.
The first seven sections of this volume have been carefully revised,
but required no serious alteration. The eighth section required very
extensive changes and additions, due to the great progress of Tropical
Medicine in the last fourteen years. The Society is much indebted to Dr.
Andrew Balfour, C.B., C.M.G., Director-in-Chief of the Wellcome Bureau of
Scientific Research, who has very kindly revised and extended the Medical
Hints in the light of his wide experience in the Sudan and in the East
during the War.
In the instructions for the use of drugs the word “tablet” has been
used to denote products compressed in the form usually described by a
proprietary word that belongs in law only to the products of a particular
firm.
