This work, of course, the author had to do, when he was lecturing to the ?Archaeology?" class. As some of his conclusions and points of view were thought by his friends to be interesting and worth placing before scholars, they were embodied in a course of five lectures which he delivered last cold season before the public in the University. It is these lectures that have been published in this volume, and he is glad they are now before scholars for their constructive and helpful criticism at the University of Calcutta in 1920-21. The lectures are lengthy and scholarly and discuss (i) the importance of the study of Numismatics (ii) Antiquity of coinage in India (iii) Karshapana coins and their antiquity (these are coins which are mentioned in the Jataka tales) (iv) Science of coinage in Ancient India, and finally (v) The history of coinage in ancient India. So, the subject matter of the book is good and based on Numismatics which generates lot of interest amongst the student of history and researchers.
