    THIS monograph gives a detailed account of the element gallium, which is now available on the market. After a historical introduction, it specifies the sources of gallium and the methods of extracting the element from them. The physical and chemical properties of gallium and of its alloys and compounds, including organo-metallic compounds, and the analysis of gallium, are described with 450 references to literature and 15 patents. Since 1932 gallium has been separated from the by-products of the copper schist of Mansfeld by the Vereinigten Chemischen Fabriken at Leopoldshall, and the price is now about 10 marks per gram. The metal has a very low melting point, 29-78 °, and remains supercooled much below 0 °, and a high boiling point, so that its use in high-temperature thermometers in quartz has been the object of research. Gallium compounds have also found application in pharmacy. The book contains some original observations by the author and is a valuable survey of the present knowledge of gallium and its compounds.

    Das Gallium:

    eine kritische Würdigung der Erkenntnisse mit experimentellen Beiträgen. Von Dr. Erich Einecke. Pp. 155. (Leipzig: Leopold Voss, 1937.) 12 gold marks.
