A bstract Densities and refractive indices were measured on two parallel series of glasses, one containing TiO 2 and the other PbO. It was found that for equal mol per cent additions of TiO 2 and PbO the glasses have quite similar refractive indices. From the data given, the molecular refractivities were calculated, and a marked similarity was found in the effects produced by TiO 2 and PbO.
