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.
