Gynaecological Society in 1886, introduced by Fordyce Barker, various
eminent gynaecologists declared in favor of the doctrine, more or less
cautiously. (_Transactions of the American Gynaecological Society_, vol.
xi, 1886, pp. 152-196.) Gould and Pyle, bringing forward some of the data
on the question (_Anomalies and Curiosities of Medicine_, pp. 81, _et
seq._) state that the reality of the influence of maternal impressions
seems fully established. On the other side, see G.W. Cook, _American
Journal of Obstetrics_, September, 1889, and H.F. Lewis, ib., July, 1899.

authorities, from Soranus of Ephesus onward, consider, however, that
sexual relations should cease during pregnancy, and certainly during the
later months. Cf. Brenot, _De l'influence de la copulation pendant la

edition, p. 151) that during normal pregnancy diseases with excess of uric
acid in the blood (headaches, fits, mental depression, dyspepsia, asthma)
are absent, and considers that the common idea that women do not easily
