In a general account of the properties of torbernite given by the present author in this magazine in 1916 it was shown that the transition from torbernite to the first dehydrationproduct, known as meta-torbernite I (meta-kupferuranit), was dependent

The isomorphous replacement of one element by another, in a pair of crystalline salts, is usually accompanied by a substantial change in the molecular volume. This progression is exceptionally well illustrated in the 'eutropic' elements K, Rb, Cs, an

( Read, November, 1949). PROBLEMS OF THE SEDIMENTARY IRON ORES. BY A. F. HALLIMOND It is difficult to review the earlier phases of a subject without referring to much that has since become common ground. I hope I may be forgiven if in these few intro

Measurements with the petrological microscope may be divided into those made with the orthoscopic and those with the conoscopic arrangements. It was early realized that if the micrometer scale or compensator was inserted in the focal plane of the ocu

The Paper deals with the characteristic or volt-ampere curves given by various Point contacts when the voltage is slowly varied. The curves were plotted by means of a form of rocking mirror galvanometer, which projected the characteristic as the path

In the first part of this paper it was shown that the acid section of the mica group could be divided into two main series, the potash micas and the lithia micas. The molecular ratio of potash to silica was 1 : 6 and the micas were therefore represen

Although the methods of magnetic survey in the field are now well established, there have been relatively few direct determinations of the magnetic properties of the rocks concerned. Conclusive evidence has now been obtained that some of the natura

Considerable interest attaches to the estimation of the volume occupied by the several atoms in a crystalline compound. For the complete molecule a volume can at once be calculated from the density and the chemical composition, but the further subdiv

As one of the first excavations of a hillfort in the Scottish Borders, this excavation aimed to discover some of the culture and priorities of the Iron Age and Roman inhabitants. Four phases of habitation were identified, although not all of them cou
