——— PERSONNEL PLACEMENT —— originate in Africa? BACKGROUND 10 EVOLUTION IN AFRICA Edited by W. W. Bishop and J. D. Clark Discoveries of the last decade are confirming Darwin’s famous speculation about the importance of the prehistory of Africa andits role in the origin of man, the developmentof animals and plants, and the changes in land areas. This book surveys the new evidence gathered in Africa by palaeontologists, geologists, archaeologists and other scholars — including Dr. L. S. B. Leakey who describes his much-discussed mammalian finds from Miocene and Pleistocene East Africa. A bilingual book, the English papers are preceded by French abstracts, and vice-versa. The editors are, respectively, lecturer in geology at Bedford College, University of London, and Professor of Anthropology at University of California in Berkeley. $27.50 ATLAS OF AFRICAN PREHISTORY Compiled by J. D. Clark The first atlas of its kind to represent the whole of any continent. Eminently usable — consists of twelve base maps of ecology and paleo-ecology, with 38 transparent overlay maps showing political boundaries and cities, cultural distributions, fossil fauna,sites of fossil man, and present-day discontinuous distribution of certain mammals and birds. Base maps, for the most part on a scale of 1:20 million, were drawn by Eve Kemnitzer. $32.50 Both these books are published with the aid of the WennerGren Foundation and under the auspices of the Pan-African Congress on Prehistory.
