The most rapid rate of decomposition was found with mixed plankton, a slower rate with diatoms, and a still slower one with plant protoplasm foreign to sea water (yeast cells). To study this relation further we undertook to compare the decomposition of diatoms (Nitzschia) with that of a protozoan (Tetrahymena gelei) grown in bacteria-free culture. For this purpose, two decomposition series of Nitzschia wrere started, No. 54 (Figure 2) in harbor water, and No. 55 (Figure 3) in deep-sea water collected from below 1000 meters 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. ).
