Extract

In 1888 Tammann, applying a form of the gas current saturation method to the measurement of the dissociation pressures of salt hydrates, obtained results which were uniformly higher by from 2 to 5 per cent, than the results obtained by Frowein with the tensimeter. This anomalous behaviour was confirmed, in Nernst's laboratory, by Schottky, who reported that the initial dissociation pressures developed in tensimetric measurements were, in cited cases, higher than the equilibrium values. In 1911 Partington, re-studying certain of the facts, added further confirmation by the use of the gas current saturation method in a somewhat altered form.
