When marine animals such as Mesiciotefl ^^ and Carciniis'^''- ^^'* are transferred to dilute sea water, reverse reactions occur, and the blood constituents are diluted in different proportions. These changes occur rapidly during the first few hours and then more slowly, equilibrium usually being reached in 2 to 7 days. A relatively constant body weight is maintained. The net result is that the ratios among the different ions change. Fig. 24. Concentrations of sodium, potassium, calcium, and of total protein (PR) in the blood of Carcinus as a function of the concentration of the medium (dilute sea water) in freezing point (Ao). From ; with a change in total tonicity. Blood proteins decline with increase in blood salts (Fig. 24). Changes in blood chloride have been followed m numerous species. In dilute sea water the blood chloride concentration decreases, but some regula- tion occurs, and below a certain concentration the blood chloride remains nearly constant (Mesidotea, Fig. 23). In Gamviarns, correspondence of blood chloride to chloride in the medium occurs in higher concentrations, and regu- lation to a constant blood chloride occurs in very dilute media (Fig. 25)..
