We have again to acknowledge very gratefully the indispensable help given to our enterprise by Dr. Bartholomew with his unfailing knowledge and skill. Also to thank Miss Edwardes for her working gazetteer which makes reference easy, and Mr. G. C. Brooke of the Department of Coins and Medals at the British Museum for his notes on the coinage, and for his arrangements of the specimens which serve so vividly to illustrate the historical side of the atlas.
