The strength of the sol was obtained by the coagulation of a known volume of the sol. [...] The foregoing results show that in every one of the 42 cases of the nineteen sols examined ik the refractive index of the colloid is increased sensibly as a result of thermo-ageing '. This suggests the production of a common change so as to vary p. in the same sense in all the cases. [...] This would depend upon the refractive index of the colloid material that of the continuous medium the size (presumably the shape) the electrical charge of the particles and their ionic atmophere. [...] An increased dispersion of the colloid that is a diminution of the particle-size for example would increase the proportion of the colloid matter in the optical path ; it would therefore bring p. nearer to that characteristic of the dispersed phase that is increase it since the refractive index of any of the suspended materials is greater than that of the dispersion medium (A. [...] Of the various methods available for the synthesis of hydroxanthraquinones the condensation of nitrophthalic anhydrides with phenols and phenol ethers and the subsequent conversion of the resulting nitrobenzoylbenzoic acids into aminand hydroxybenzoybenzoic acids followed by ring-closing is one of the most fruitful.
