An apparent monthly fluctuation in response of Ditgesia to all four strengths of gamma sources (from X to 9 X background) presented on the right over the period from September 27 to November 5, 1962. B. A suggested semi-monthly fluctuation in response during three semi-monthly periods (October 20-December 4) with left-turning during four days before new and full moons, right-turning for two days afterwards, and high dispersion of responses for the remainder of the cycles. C.
