[Pp. 57], [58.] Single Life in Its Relation To Sanity And Mortality.—The extraordinary statements in the text are vouched for by Dr. Casper, Medicinische Statistik, vol. ii. p. 164, and Dr. Reich, Geschichte, Natur, und Gesundheitslehre des Ehelichen Lebens, pp. 510, 511. We have compared the reports of a number of asylums for the insane, and find the proportions very nearly as great as stated by these authorities.
[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.
[P. 94.] Contagion of Phthisis.—See Dr. William A. Hammond's Treatise on Hygiene, p. 438, for air-space required by a healthy person. The contagion of phthisis is maintained by many authorities—among others, Dr. W. W. Gerbard (see Pennsylvanian Hospital Reports for 1868, p. 266). Professor Castan has recently collected, in the Montpelier Médicale, a variety of facts, which seem to show that tuberculosis may be communicated from a diseased to a healthy person by transpiration, breathed air, and living together (Press and Circular, March 10, 1869). In regard to the inoculation of tubercle, we have reference to the well-known experiments of M. Villemin, of the Hôpital Val-de-Grace, Paris. In this connection we may record an instance of recent medical heroism. M. Lespiaud, attached to the surgical department of the Val-de-Grace, in presence of several of his colleagues, extracted granular matter from the body of a phthisical subject, and introduced it under his own integument. This zealous investigator into the etiology of tuberculosis has thus exposed himself in a courageous way for the benefit of science, to the effects of a most dangerous and merciless disease.
[P. 96.] The Dignity and Propriety of the Sexual Instinct.—Dr. Edward John Tilt is the medical writer referred to (see Uterine Therapeutics, pp. 95, 313). See also Bosquet, Noveau Tableau de l'Amour Conjugal, vol. ii. p. 2, etc.; Rousel, Système Physique et Moral de la Femme, p. 211; Menville, Histoire Médicale et Philosophique de la Femme, vol. i. p. 36 et seq.; Raciborski, De la Puberté, etc., p. 45.
[P. 99.] On the Indulgence and Restraint of Sexual Desire.—Menville, vol. ii. p. 91; Bosquet, vol. ii. p. 280; Economy of Life—or, Food, Repose, and Love, by George Miles. Dr. Edward Smith, in his valuable work on Cyclical Changes in Health and Disease, has collected extensive statistics showing the effect of the time of conception on the viability of the fœtus. The quotation is from Carpenter's Human Physiology, p. 753.
[P 103.] See Lancet for March 6, 1869, p. 337, for report of discussion in the Pathological Society of London upon the physical degeneracy resulting from procreation during intoxication. Authorities could be cited at length upon this subject, but it is not necessary. See Huleland's Art of Prolonging Life, p. 207.
[Pp. 106-114.] Sterility.—For statistics referred to, see Dr. Matthews Duncan, Fecundity, Fertility, and Sterility (Edinburgh, 1866), p. 181 et seq.; Dr. Tilt, Uterine Therapeutics, p. 291; Dr. Edward Reich, Gesundheitslehre des Ehelichen Lebens, Th. ii.
