The Trustees of the British Museum have at last found
adequate space, in the fornier Waddesdon Room, for the exhibi- tion of select coins and medals from their magnificent collections. Mr. G. F. Hill, the Keeper of the Coins, has celebrated the occasion by preparing a third and revised edition of the Guide to the Department of Coins and Medals (British Museum, Is. 6d. net)—an excellent popular handbook, with eight plates and many illustrations in the text. One of the illustrations repro- duces the notorious medal struck by Pope Gregory Xlii to commemorate the Massacre of St. Bartholomew ; near it is that other production inspired by hatred and revenge, the German ` Lusita.nia ' medal.
