P. 70. INTERMARRIAGE OF RELATIVES.--The view we advocate on this point, we know, is neither the received nor the popular one. In the middle ages it was forbidden to intermarry within the seventh degree of consanguinity; but this and all other regulations were based on theological and political, not physiological, grounds. Among others, Dr. Nathan Allen has insisted on the danger of consanguineous marriages (_Journal of Psychological Medicine_, Volume ii). But other very careful and recent students adopt the view of our text: for instance, Dr. F. J. Behrend, _Journal für Kinderkrankheiten_, December, 1868, p. 316; Dr. A. Voisin, in the reports of the _Paris Académie de Médecin_,1864, 1865, and 1868; and Dr. H. Gaillard, in the last edition (1868) of the _Dictionnaire de Médecine et de Chirurgie Pratique_. All the statements in the text are supported with incontrovertible evidence by these writers. If we are asked how to meet the seemingly alarming array of allegations by Dr. Bemiss, the Kentucky physician referred to in the _Transactions of the American Medical Association_ for 1859, we would refer to Dr. Behrend's articles, where the researches of Bemiss are severely criticised. For Dr. Edward Smith's assertion, see his _Essay on Consumption_, p. 244 (Philadelphia, 1865). P. 80. COMMUNICATION OF VENEREAL DISEASES.--Many instances are recorded where a drinking-glass, a spoon, a fork, or a handkerchief has infected innocent persons with these terrible diseases (see Cullerier, _Atlas of Venereal Diseases_, p. 43). They are communicated from the male to the female, or from the female to the male, with equal facility, and either parent can transmit them to the children. The physician referred to is Dr. Sigmund, in the _Humboldt Medical Archives_, 1868. P. 83. SYMBOLISM.--See Dr. Carus, _Symbolik der Menschlichen Gestalt_, the most scientific work ever written on physiognomy, phrenology, and allied subjects. Pp. 90, 91.--See Raciborski, _De la Puberté et de l'Age Critique chez la Femme_, p. 133; Tilt, _Uterine Therapeutics_, p. 315.
