Urine concentration changes and 48-hour blood values in winter Hcmigrapsus nrcgonensis, at 5° C., as a function of time in the experimental salinities. Each point represents the mean of the measurements of 10 animals for each time period. Urine values are indicated by closed circles (• ), blood values (Dehnel, 1962), by open circles (O). perimental conditions after the 3-hour and 24-hour samplings, and discarded after 48 hours. Measurement of the total osmotic concentration of urine samples was accomplished by the method of melting point determination described by Jones (1941) and modified by Gross (1954). The data were analyzed for salinity and temperature effects and seasonal dif- ferences by means of Student's "t" test. The same test was applied to the differ- ences between mean osmotic concentrations of blood (Dehnel, 1962) and urine.
