v! PEEFACE fourth great Buddhist Council, the Council which gave con- sistency and official sanction to the doctrines of Northern Buddhism. As regards the philological importance of the Indo-Greek coins, it must not be forgotten that they provided the key to the Kharosthi script. Many documents written in the Kharosthi character have been discovered recently by Sir Aurel Stein in Khotan. A further interest lies in the shape of these coins, many of them, being square or oblong, and in the characteristic designs of gods and animals as conceived by the oriental Greek artist. I have modelled this Catalogue on Professor Gardner's The Coins of the Greek and ScytMc Kings of Bactria and India in the British Museum, which, though published in 1886, is still the best guide to the student. I have derived much assistance from the first volume of the Indian Museum Coin Catalogue, by Mr. Vincent A. Smith, This was published at the Clarendon Press in 1906. In the Introduction I have used material from my paper *Ihe Place of Coins in Indian History5 (Journal of the Panjab Historical Society). I have been unable to arrange for a Kharosthi fount for the inscrip- tions in this language. The system of transliteration is that used by G. Biihler in his well-known palaeographical tables published in the Grundriss der Indo-Arischen Philologie. It is hoped that the information contained in the Text will be found accurate and up to date. Points worthy of attention have been noticed in the body of the Catalogue. I have done my best to exclude forgeries. The one or two doubtful coins which have been included, are marked with an asterisk. The Catalogue contains lists of coins unrepre- sented in the Museum, which lists I have made as complete as possible. Supplementary Plates at the end of each Section contain reproductions of important and interesting coins which are absent from this Collection. Owing to the comparatively small scope of this work,
