Degree of left turning is indicated by concentric circles inside heavily inked one, and right turning by concentric circles outside of it. upon finding 6 of the 8 directional differences (NE, E, SE, S, SW, and NW) statistically significant. Influence of experimental magnetic-field changes on response: Since there was conspicuously a compass-directional relationship of the character of the response to the 2 volt/cm, change in electrostatic field it became of interest to learn whether this was directly dependent upon responsiveness of the worms to the magnetic field. Consequently, an additional experiment was conducted between February 17 and April 11, 1962. This comprised, until March 13, observing in the morning the effects upon mean paths of the electrostatic-field difference for North- and South- directed planarians and for North-directed ones under experimental conditions of an artificial magnetic field differing from the earth's only in that the natural 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. ).
