Sea water samples, still hot from volcanic emanations were taken in a bay of Nishinoshima-Shinto Island just after volcanic activity had ceased and were analysed for borate-B, fluoride-F and bromide-Br. The hot water is considered to be formed by the conservative mixing of volcanic emanations with sea water, and the emanations contained <I>Cl</I>, <I>B</I>, <I>F</I>and<I>Br</I>in the ratio of 1: 1.84×10<SUP>-3</SUP>: 0.474×10<SUP>-3</SUP>: 6.47×10<SUP>-3</SUP> by weight.<BR>Ratios<I>B/Cl</I>and<I>F/Cl</I>can be used as effective measures of the contribution of volcanic emanations to sea water.
