Excerpt from Proceedings of the Cambridge Philosophical Society, Vol. 8: October 31, 1892 May 27, 1895 The retiring President, Prof. G. H. Darwin, addressed the Society upon the History of the Society during his tenure of office. Sir Robert Stawell Ball, Lowndean Professor of Astronomy and Geometry, and Mr R. A. Sampson, M.A., St John's College, were elected Fellows of the Society. The following communications were made to the Society: (1) Note on the Determination of Low Temperatures by Platinum-Thermometers. By E. H. Griffiths, M.A, Assistant Lecturer at Sidney College, and G. M. Clark, B.A., Sidney College. In connexion with Profs. Dewar and Fleming's recent work on the resistance of certain metals and alloys at very low temperatures, and the suggestion that they have made - viz. that the resistance of certain pure metals (amongst which is platinum) vanishes at absolute zero, - the following facts may be of interest. The following table gives the constants and results: The actual numbers used in these calculations are those taken from the papers referred to in column 2. All the other thermometers mentioned by Griffiths (Phil. Trans. A. 1891, pp. 43-72)were made with single electrodes for rapid observations; and thus every observation includes their stem-resistance, which evidently cannot become zero, so that the above investigation with their constants would be of no use.
