Graph compiled from the data presented in Tables III. and IV. showing the results of long exposures of worms to NaOH solution, pH Per cent, of increase or decrease, normal respiration being taken as 100, on the ordinate and number of days on the abscissa. Heavy line represents experiment in ordinary water and broken line experiment in boiled well water. The drop on the last day in each experiment shows the drop in respiration from NaOH solution to 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 La
