The effect of cyanide at various concentrations on the oxygen consumption of normal house fly pupae. Solid circles represent normal oxygen consumption. Open circles, crosses and triangles represent oxygen consumption in presence of, respectively: 3X 1CM M, 4 X 10-3 M, and 5 X Kh2 M, cyanide. thus evident that oxygen consumption must decrease rapidly at this critical period. This interpretation is in agreement with measurements of oxygen consumption in Drosophila pseudoobscura by Dobzhansky and Poulson (1935), and with the un- published data of Bodenstein and Sacktor on larval and pupal cytochrome oxidase in D. virilis, and of Levenbook (1950) on respiration in 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. ).
