II. The latent heat of evaporation of water

Abstract

Although the enquiry described in the paper, of which this communication is an abstract, has engaged my attention for the last two years, the actual experiments on which the conclusions are based were not performed until the months of September and October, 1894. Many difficulties in the construction of the apparatus had to be overcome, also the necessary standardisation of the instruments occupied my leisure time for some months. The apparatus was designed so as to enable me to perform experiments at temperatures from 10° to 60° C., and I hoped to carry out my investigations over that range.
