Sulphur and sulphur derivatives

TLDR: Auden as mentioned in this paper gives a very readable and accurate account of the manufacture and uses of sulphur and its derivatives, especially sulphuric acid, and his book should prove useful to students and general readers.

Abstract: DR. AUDEN gives a very readable and accurate account of the manufacture and uses of sulphur and its derivatives, especially sulphuric acid, and his book should prove useful to students and general readers. Although two illustrations of the Gill furnace are given, its mode of operation (which cannot be seen from the illustrations) is not mentioned. The changes observed on heating sulphur aie not quite correctly described (p. 5). Moreover, the statement (p. 29) that “almost the whole supply of ammonium sulphate is at present derived from the distillation of coal” refers only to English practice; in more progressive countries very large quantities are produced from atmospheric nitrogen. Although the earlier history of the contact process is given, the real commercial process (p. 61) is not ascribed to any particular inventor—the work of the Badische Co. would seem worthy of mention, and diagrams of the apparatus would also be useful.Sulphur and Sulphur Derivatives.By Dr. H.
