Invariably one end of the tentacle would pull out of one of the electrodes during contraction. Thus, it was not possible to measure the conduction velocity of stimulated TCP's. Overt behavior of tentacles was observed with a dissecting microscope and recorded manually using telegraph keys attached to two channels of a 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. ).
