Relation between intensity of pseudoflash in air of smeared photogenic tissue of P. pyralis, and degree of hypoxia. Tissue exposed to each oxygen concentration for two minutes, then flushed with air. Intensity plotted on ordinate in per cent of glow intensity in air. In some instances, however, it was observed that both spontaneous flashes and vari- ous types of induced luminescence involved only one of the segments, or only parts of one or both. Furthermore, the type of luminescence displayed sometimes differed in different regions of a single organ or even changed in the course of an 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. ).
