Kiuhteen per cent cells. Temperature 24° C. Figure 3 shows a number of carbon dioxide absorption curves for the carp, frog. Ainphhtnia. turtle, and man, representative of four of the classes of vertebrates. All of the curves for the lower vertebrates resemble each other more than they do the mammalian curve. In these few examples the amphibia occupy an intermediate position with respect to carbon dioxide content between the teleostian carp and the reptilian turtle. The marked flatness of the turtle curve is attributed by South- worth and Redfield (1926) to the low corpuscular volume, the low lib of turtle blood. \Vastl (1928) gives the same sort of explanation for tli' 'tially parallel curve for carp blood. A similar explanation for the flatness of the Amphiuma curve is indicated just as it is lor the other lower vertebrates, since the blood of all of these animals shows a corpuscular volume only about one-half to one-third that of human 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. ).
