[The Royal Asiatic Society are indebted to Major F. W. Stubbs, R.A., for the illustrative materials of the following paper. The facsimile of the inscription has been executed in so perfect a form as to be freely legible to ordinarily practised eyes. As Professor Dowson had already distinguished himself in the decipherment of Bactrian Pali writing in his previous articles in this Journal, the explanation of this inscription was, as a matter of course, confided to him. The result appears below. The facsimile of the inscription itself has been reserved for publication, in association with the Mathura series alluded to by Professor Dowson.
