Notes
For the valuable assistance given me in procuring the necessary literary works I wish to express my sincere gratitude to the officials of the Nordiska Museet library. For most useful information I am also indebted to Professor P. Schebesta (Wien), Professor M. Schulien (Rom) and Dr. J. Söderström (Stockholm). Particularly helpful were Dr. J. Hornell (St. Leonards‐on‐Sea) and Dr. W. Schilde (Plauen) which have given me notes from works that have been inaccessible.
