Spring, W. Archives Neerlandaises des Sciences Exactes et Naturelles (1901), 6(ii), 257-61; SciFinder (Chemical Abstracts Service: Columbus, OH); https://scifinder.cas.org (accessed July 8, 2010). No combination took place on subjecting an intimate mixture of 2 mols. of cupric oxide and 3 mols. of sulphur to a pressure of 10,000 atmospheres. Combination took place violently when the pressure on a mixture of 2 mols. of cuprous oxide and 3 mols. of sulphur rose to 8000 atmospheres; the pressure was increased gradually so that no heating by compression took place. Sulphur dioxide was formed and the residue consisted only of cuprous sulphide (2Cu2O + 3S = 2Cu2S + SO2). The ignition temperature of this mixture at the ordinary pressure is about 126°, and pressure to the extent of 8000 atmospheres has the effect of lowering this by more than 100°. The ignition temperature of the mixture of cupric oxide and sulphur could not be determined for the sulphur inflamed at 250°, but it must be higher than this. It would appear that the point of inflammation is a function of the pressure, and the experiments are being continued to ascertain if this is quite general.

Spring, W. Recueil des Travaux Chimiques des Pays-Bas (1901), 20, 79-80 ; SciFinder (Chemical Abstracts Service: Columbus, OH); https://scifinder.cas.org (accessed July 8, 2010). The sp.gr. of dry cuprousiodide is 5.653° at 15°, not 4.41° as stated by Schiff (Annalen, 1858, 108, 24); the molecular volume is thus 33.61, and is less than the sum of the atomic volumes of the elements (34.73), showing that, as usual, a contraction has occured in combination.

Spring, W. Zeitschrift fuer Anorganische Chemie (1901), 27, 308; SciFinder (Chemical Abstracts Service: Columbus, OH); https://scifinder.cas.org (accessed July 8, 2010). Schiff obtained a value of 4.41 for the specific gravity of cuprous iodide, while a redetermination by the author gives 5.631. The importance of this lies in the fact that cuprous iodide is now seen to be formed from the elements with contraction, whereas Schiff's figure called for twenty-four percent expansion.
