ANALYSIS OF WEATHERED GLASS FROM YORK MINSTER

Non-destructive analyses are reported of a twelfth century stained glass panel from York Minster. The main conclusion from the results is that the observed differences in severity of corrosion between various glasses may be explained by variations in the proportions of potassium and calcium.     

Population relationships of later Pleistocene hominids: A multivariate study of available crania

The Neanderthal populations of the Upper Pleistocene have been regarded by a number of anthropologists as direct ancestors to modern man. Results of multivariate analyses conducted in this study suggest that early Neanderthal crania were morphologically more like modern Homo sapiens than were the later Neanderthals. The implications of these results are discussed in the light of archaeological evidence and comparative studies of Pleistocene crania from outside Europe.
