Regression lines drawn through average melting points of blood at average melting points of water of —, —, , — and —° C. Key to lines on figure. at ° C. the slope of the line has changed markedly (b == .613), the low values are nearly the same as those at 48 hours but values in the upper salinities have raised. The slope of the line indicates a trend toward isotonicity. At the same time the controls in room temperature, ° C., have returned essentially to the same point at which they started (b = .323). Analyses of covariance of data for initial experimental and control animals paired with 48-hour controls, 96-hour controls and experimental animals at ° C. show no significant difference in slope or elevation (P -- ), but the line for animals in ° C. water differs significantly in slope. In larger astecus (Fig. 3), essentially the same circumstances prevail though in accented form. The animals hypotonic to the sea water from which they were taken show a quick response to lowered salinities at room temperature (b = .427). At 48 hours with temperature lowered to ° C. the slope of the line is approximately the same as in the beginning but the concentration of all bloods has been lowered (b -- .385). At 96 hours the approach of the slope of blood salinities to the line.
