Sea water of different oxygen tensions was procured by boiling and subsequent mixing with normal sea water. In this manner sea water of any desired oxygen tension could be 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. ).
