Publisher's Synopsis
Excerpt from Transactions of the American Microscopical Society, 1911, Vol. 30: Published Quarterly by the Society
If my informant was correct in his dates, the third appearance would occur at high tide. It is possible that the first appearance of the season, involving a release of gametes, is stimulated by low tide or by the coincidence of low tide and approaching dark; that the time necessary for renewal of reproductive bodies has been established at approximately the lunar month by a series of circum stances, internal and external; and that the release of the sexual products occurs on the first approach of dark after their maturity irrespective of the height of the tide at the time.
Parallel instances of periodicity in the formation and release of sexual bodies are numerous, in, which both tide and light appear to play a part.
