Fossil Man in China. In view of the Fifth Pacific Science Congress and the Fifteenth Geological Congress this summer at Vancouver and Washington respectively, the Cenozoic Research Laboratory of the Geological Survey of China has summarised existing knowledge relating to Peking man and the Cenozoic history of China in a single volume ("Fossil Man in China”, Geological Memoirs, Series A, No. 11). Although contributions from members of the Laboratory have appeared in various publications, which cover practically the same ground, not only is it a matter of convenience to have the material collected in one volume, but there is also the added advantage of the perspective given by the editorship of Prof. Davidson Black, the director of the Laboratory, after discussion of various points with members of the staff, who have been responsible for work in the field. P. Teilhard de Chardin is the author of the first chapter, which deals with the Choukoutien deposits and the late Cenozoic of China; Prof. Davidson Black discusses the Sinanthropus skeletal remains and other north China fossil hominids; and P. Teilhard de Chardin deals with the Sinanthropus cultural remains and summarises the evidence of other ancient cultures in north China. Prof. Black emphasises the fact that although each section is based on the individual work of the authors, the conclusions represent their unanimous opinion as a group. As thus presented in new form, and especially as representing the considered conclusions of P. Teilhard de Chardin, the material will be found to repay careful examination. It is pointed out, for example, that the faunistic evidence of Choukoutien points to an interchange with the south, but that the situation provides no sound argument for a southern derivation of Sinanthropus, since Pithecanthropus was provided with a dentition much too highly specialised to have been ancestral to Sinanthropus. On the other hand, certain difficulties remain, such as those which have led Prof. M. Boule for one to question the attribution of the development of a lithic industry relatively so advanced and the use of fire to a being of a generalised type such as Sinanthropus, differing essentially on one hand from modern, Neanderthal and Rhodesian man, and on the other from the anthropoids.
