Much has been written, much has been said in various places, and amongst them in this Society, about Buddha, and the religious system which bears his name, yet it may be suspected that the notions which have been entertained and propagated, in many particulars relating to both the history and the doctrines, have been adopted upon insufficient information and somewhat prematurely disseminated. Very copious additions, and those of a highly authentic character, have been, but very recently, made to the stock of materials which we heretofore possessed, and there has scarcely yet been sufficient time for their deliberate examination. Copious also and authentic as they are, they are still incomplete, and much remains for Oriental scholars to accomplish before it can be said that the materials for such a history of Buddha as shall command the assent of all who study the subject, have been conclusively provided. I have, therefore, no purpose of proposing to you in the views I am about to take, that you should consider them as final; my only intention is to bring the subject before you as it stands at present, with some of that additional elucidation which is derivable from the many valuable publications that have recently appeared, and particularly from the learned and authentic investigations of the late Eugene Burnouf, the only scholar as yet who has combined a knowledge of Sanscrit with that of Pali and Tibetan, and has been equally familiar with the Buddhist authorities of the north and south of India: unfortunately he has been lost to us before he had gone through the wide circuit of research which he had contemplated, and which he only was competent to have traversed; and although he has accomplished more than any other scholar, more than it would seem possible for any human ability and industry to have achieved, it is to be deeply and for ever regretted that his life was not spared to have effected all he had intended, and for which he was collecting, and had collected, many valuable and abundant materials.
