The pressure at half saturation of the hemo- globin is 40 mm. of oxygen when the CO., tension is 13-14 mm. com- pared with the average of 23 mm. O2 tension with the CO2 tension of 1 mm. or less. The effect of CO2 upon the oxygen dissociation curve of freshwater salmon was not determined, but from the maximum effect of CO2 on the oxygen capacity in fresh and saltwater fish it seems likely 100 p 9O :8O
