Chemistry of Sulphur and Selenium

Abstract

IT is more difficult to write an adequate review of the tenth volume of Mellor's “Comprehensive Treatise” than it was to review the earlier volumes, since the author's methods of presentation have long since become standardised and are now quite well known. Indeed, an intelligent reader might hope to predict the general characteristics of the volume on sulphur and selenium by studying those on the related elements, in the same way that Mendeleff predicted the properties of eka- and dwi-manganese from those of contiguous elements in his Periodic Classification. From this point of view, the new volume is ‘true to type’ and presents no marked contrasts with those which have preceded it. An. inspection of the paragraphs dealing with subjects with which the reviewer is most familiar compels him, however, to pay a tribute of admiration to the almost uncanny way in which even the most obscure researches have been included in the author's survey.

A Comprehensive Treatise on Inorganic and Theoretical Chemistry.
