Any intelligent physician will acknowledge the weight to be assigned to such names.

[P. 180.] Mothers' Marks.—See a very interesting article by Professor Wm. A. Hammond, in The Quarterly Journal of Psychological Medicine and Medical Jurisprudence, January, 1868, p. 1, in which he says, in regard to the influence of the maternal mind over the fœtus in utero: 'The chances of these instances, and others which I have mentioned, being due to coincidence, are infinitesimally small; and though I am careful not to reason upon the principle of post hoc ergo propter hoc, I cannot—nor do I think any other person can, no matter how logical may be his mind—reason fairly against the connection between cause and effect in such cases. The correctness of the facts only can be questioned: if these be accepted, the probabilities are thousands of millions to one, that the relation between the phenomena is correct.' See also Dr. J. Lewis Smith, Diseases of Infancy and Childhood, 1869, p. 21; Philadelphia Medical and Surgical Reporter, vol. xix. p. 359.
