South and East African Stone Age Typology

Abstract

IN my letter in NATURE of September 21, p. 475, in the fifth paragraph, I said that the oscillation which marks Bed III at Oldoway and the Intrapluvial in Pluvial II, in Uganda, ” may be equated with that between the Kamasian and Gamblian” of Kenya. That was wrong, for it has recently become clear that following the Uganda Pluvial If oscillation, and separated from it by a considerable thickness of sediments, there were two less marked breaks. Study of the implements from these two non-pluvial beds reveals the fact that the last actually represents the break equivalent to that between the Kenya Kamasian and Gamblian pluvials, since in it were some tools (Late Acheulean) comparable to the Nanyukian. The latter stage was found by Dr. J. D. Solomon on the slopes of Mount Kenya in a rubble which was regarded as marking the Kamasian-Gamblian Interpluvial.
