The author prepared "milk of sulphur" by treating KnS with dil. HCl, and also by passing H2S into FeCl3 solution. The S from the K2Sn was completely sol. in CS2 and had a density of 2.0555, which is approximately the same as that of rhombic S. That from H2S was soluble CS2 to the extent of 96.8% only, and the density of the soluble portion was 2.0658, while that of the insoluble was 1.8686. The greater part of the sulphur from the K2Sn was therefore identical with that from H2S. This conclusion was confirmed by measuring their specific heats
