This volume contains a Catalogue of the Roman Medallions in the British Museum. The metal of each specimen is given, and its size in inches and tenths. The weight of all examples in gold and silver is stated in English grains. Tables for converting grains into grammes, and inches into millimètres, as well as into the measures of Mionnet''s scale, are given at the end of the volume. A table of dates and titles also there given will enable the reader to find the year or period to which each medallion may be ascribed.
