In 1902 there were published the results of an extended series of measurements of the capacity for heat of water at different temperatures between 0° and 100°C. The continuous method of calorimetry was employed in the work, the details of which were developed by Prof. H. L. Callendar and myself. A steady electric current was used to heat a steady flow of water through a fine bore tube, bringing about steady temperature conditions in the calorimeter. The energy given in joules per calorie was expressed in terms of the international electric units, and was consequently dependent on the values of the standards used in the measurements. The very greatest possible care was exercised in selecting the standards employed and in making sure that they represented the values assumed for the international electrical units. Previous to the commencement of the investigation of the capacity for heat of water, several years were devoted to a thorough study of the Clark cell as a standard of electromotive force and to the determination of the temperature coefficient of the Clark cell. From a large number of cells suitable examples were selected which were as perfect as could then be obtained. Additional cells were also made at different times and with different materials, in order that those actually used in the investigation could be expressed in terms of the mean of as large a number as possible. In addition, a further investigation of the Weston cell was made, and the mean of all the Clark cells was compared with the mean of all the Weston cells. The value of this ratio was found to be Clark at 15°C. / Weston at 20°C. = 1·40666, which is practically coincident with the value of the ratio found by Jaeger and Lindeck for the cells prepared at that time at the Reichsänstalt. They found Clark at 15°C. / Weston at 20°C. = 1·40665.
