Abstract
The CO2 dissociation curves of dogfish blood (Mustelus canis) are in most respects like those of other vertebrates, Log Pco2 plotted against Log [CO2] gives a straight line. The CO2 capacity is not affected by the degree of oxygenation of the hemoglobin. The oxygen capacities in different specimens varied from 2 to 7 v.p.c. The tension of CO2 is estimated, to vary, in arterial bloods from 2 to 6 mm. Hg; in venous bloods from 4 to 12 mm. Hg with the CO2 contents ranging from 6 to 12 v.p.c. The concentration of CO2 in the erythrocytes is usually greater than in the surrounding plasma. Reasons are given for supposing the "extra" CO2 in the red cells not to be carbhemoglobin. Two other possible explanations for the extra CO2 are discussed.
