 * 1892, edited by F. Jeffrey Bell, Journal of the Royal Microscopical Society, Williams & Norgate; page #593:
 * When embryological condensation is carried very far it gives rise to progenesis, which still further complicates pœcliogony, as in the Axolotl or in Chun’s examples of Ctenophora.
 * 1919, Charles T. Bures, in The Biological Bulletin; Volume XXXVII, №. I, page #5:
 * Giard regards some cases of pœcilogony from the standpoint of their probable origin as seasonal pœcilogony, geographic pœcilogony or as ethological pœcilogony.
 * 1922, W. R. Thompson, in Proceedings of the Entomological Society of Washington; Volume 24, №. 4, page #90:
 * The question is, however, whether the phenomenon of pœcilogony really exists: or in other words whether it might really be impossible for the trained specialist, even when fully awake to the difficulties presented by a particular case, to discover definite characters for the separation of the races in the adult stage.
 * At first sight it would seem that such differences must of necessity exist : for if two individuals produce offspring morphologically different at birth it would seem to follow logically that the differences in these offspring must have their origin in differences in the adults which it ought to be possible for the trained eye of the specialist to detect. Viewed from this stand‐point—which I have found in practice to be that of a representative and reliable specialist—the phenomenon of pœcilogony appears to be an impossibility.
