Abstract
THE International Committee of Weights and Measures at Paris has just issued an account of its business and proceedings for the past year.1 It would appear from the report of the director of the International Bureau (at Sèvres, near Paris), made to the Committee at their session in October last, that the work of the Bureau has, under the directions of the Committee, included:—Research as to the mass of a cubic decimetre oil water (giving for the specific mass of water at 4° C. a value equal to 0.9999707); the study of dividing engines; investigations, as to the dilatation of metals, the precise measurement of temperature, &c. The ordinary verification work of the Bureau during the past year has included:—The re-verification of metric standards (nietres and kilogrammes) for the High Contracting States who have given adhesion to the Metric Convention, 1875; the verification of standards (particularly thermometers, and decimetres) for a large number of scientific and official authorities; and the installation of new bases for geodetic measurements. We are glad to see that the Committee has now been able to extend and repair its laboratories at the Pavilion de Breteuil and to perfect its arrangements for undertaking electrical measurements.
