of Northern India from the beginning of the historical period to the Mohammedan conquest, with one important exception, that of the Kushan, or Indo-Scythian, period, the date of which is still open to discussion. The system of Kushan chronology adopted in this volume has much to recommend it, and is sufficiently supported to serve as a good working hypothesis. If it should ultimately commend itself to general acceptance, the whole scheme of North Indian chronology may be considered as settled, although many details will remain to be filled in.
Much progress has been made in the determination of the chronology of the southern dynasties, and the dates of the Pallavas, a dynasty the very existence of which was unknown until 1840, have been worked out with special success.
