Comparative BHCO3 : pH curves for reduced blood (except for turtle) • Curve 1 is for turtle blood at 25° C.; curve 2 for frog blood at 15° C.; curve 3 for hu- man blood at 15° C.; curve 4 for carp blood at 18° C.; curve 5 for mackerel blood at 20° C.; and curve 6 for toadfish blood at 20° C. data. The curves show that the blood of fishes is characterized by a relatively weak, those of the frog and turtle by a relatively strong, and that of the human by a more or less intermediate carbon dioxide- combining power. Human blood yields the steepest carbon dioxide- absorption, which means that it is buffered the best. These curves have been plotted at as near the same temperature in all cases as pos- sible, since it has been shown by Warburg (1922), Stadie and Martin (1924), and Cullen, Keeler, and Robinson (1925) that temperature af- fects the carbon dioxide-combining power of blood. In order that the buffering ability of several vertebrate bloods might be compared Figs. 16 and 17 were constructed. Data other than the author's have been taken from the previously mentioned sources and the pH or cH calculated on a basis comparable to the calculations made for marine fish blood. In Fig. 16 the BHCO3 : pH relationships are. Please note that these im
