The preparation of cotarnomethylurea by the action of ammonia on the chloride was not successful but with aniline reaction occurred smoothly in the cold with the formation of the anil. [...] The solutions being thus prepared were poured in the small cup of the refractometer and the readings for the refractive index of the yellow line were taken ; the apparatus had been previouly corrected for its zero error and a helium tube was excited by an induction coil to produce a continuous and prominent yellow ray for measuring the refractivities of the substances. [...] It appears from this behaviour of the cyanides that the variation of refractivity is connected also with the stable or unstable nature of the complex among other plausible factors on which the refractivity of the salts depends in general c.g. [...] The gradual increase of molecular refractivity on dilutions seems to be an abnormal behaviour of the complex molecules and this may be ascribed to the gradual decomposition of the complex ions into simpler ions whereby the electric field of the solution is intensified causing an increase in the molecular refractivity of the salts at a higher dilution. [...] In view of the above observations it may be further suggested that in the case of such complex salts as are comparatively less stable the changes of molecular refractivity on dilution may furnish a suitable method for determining the degree of stability of the complex ion of the salt.
