The monatomicity of neon, krypton, and xenon has been taken for granted on somewhat insufficient evidence. When the memoir on Argon and its companions was written it was stated that no experiments with the pure gases had been carried out on the ratio between the specific heat at constant volume and constant pressure, but that measurements made with impure samples indicated the ratio 1.67; and it was remarked that such a ratio could not have been found had any considerable portion of the mixture consisted of a polyatomic gas. Having now at my disposal relatively large quantities of pure neon, which had served Mr. Watson, and of pure krypton and pure xenon, which had served Prof. Moore, for determining the densities of these gases, it appeared advisable to fill the gaps in our knowledge of their specific heat ratios.
