¹ Sum-pa mkhan-po is said in the introduction, pp. 4-5, to have lived from 1704 to 1787, which is inconsistent with the statement there that he died at the age of 84. With that would accord Vostrikov's, A. I. 1704–88 (Tibetskaja istorićeskaja literatura, Moscow, 1962)Google Scholar. The dates are given variously elsewhere. Thus, Stein, R. A., Recherches sur Vépopée et le barde au Tibet, Paris, 1959, 113Google Scholar, 1707–88; Kuznecov, B. I., Tibetskaja letopis' ‘Svetloe zercalo carskix rodoslovnyx’, Leningrad, 1961 114Google Scholar, 1702–75; Snellgrove, D. and Richardson, H., A cultural history of Tibet, London, give 1709–86 on p. 290Google Scholar but 1704–86 on p. 245, It would accordingly have been useful to discuss the evidence in a book such as this.
