The water content of fresh-water medusae collected in Yokohama was determined both in 1949 and 1950. The mean value of water content was 98.29±0.27 per cent, in the experiment of 1949, and 98.13±0.55 per cent, in the experiment of 1950. From these determinations it may be concluded that fresh-water medusae contain water as much as from 97.5 per cent to 98.7 per cent of the body weight.
