Abstract
As regards the “red water” from a crater lake in Uganda, referred to in NATURE of April 4, p. 113, I would direct attention to a similar phenomenon which occurs at the great salt lake of Sambhar, in Rajputana. The lake brine contains sodium chloride, sulphate, and carbonate, and when it is quite saturated during the very hottest dry weather a red coloration appears of organic origin. It varies from a delicate roseate hue to a deep claret red, and there is a demand for salt which contains it, because the consumers are accustomed to the colour.
