Most of the swelling is produced at low tensions of CCX, and it indi- cates some 25 per cent enlargement of the erythrocytes. The consid- erable swelling of the cells is of a much greater magnitude than the osmotic changes which are described in mammalian blood, and there seems to be no satisfactory explanation for this phenomenon. 100 r SO -. — BRACKISH WATER SALMON COZ pressure 1 mm or less FRESH WATER SALMON COj pressure I mm or less -°- BRACKSH WATER SALMON CO, pressure 13to|4 mm FIG. 3. The maximum effect of CO2 upon the degree of oxygen saturation at P O2 == 150 mm. THE COMBINATION OF CO., WITH BLOOD In Figure 5 is shown the curve describing the combination of CO., with the blood. This curve indicates that in contrast to the reduction in oxygen capacity which occurs in fresh water, there is no significant difference in CO2 combination. FREEZING POINT OF THE PLASMA The effect of the change of external environment upon the blood plasma is demonstrated in the change in the freezing point depression. In the plasma of brackish wrater fish freezing points varied from Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
