See Bourke, Scatologic Rites of all Nations, 1891, pp. 217-219, 250 and 254; Ploss and Max Bartels, Das Weib, vol. i; H. L. Strack, Der Blutaberglaube in der Menschheit, fourth edition, 1892, pp. 14-18. The last mentioned refers to the efficacy frequently attributed to menstrual blood in the Middle Ages in curing leprosy, and gives instances, occurring even in Germany to-day, of girls who have administered drops of menstrual blood in coffee to their sweethearts, to make sure of retaining their affections.
See, e.g., Dufour, Histoire de la Prostitution, vol. iii, p. 115.
Dr. L. Laurent gives these instances, "De Quelques Phenomènes Mécaniques produits au moment de la Menstruation," Annales des Sciences Psychiques, September and October, 1897.
Journal Anthropological Society of Bombay, 1890, p. 403. Even the glance of a menstruating woman is widely believed to have serious results. See Tuchmann, "La Fascination," Mélasine, 1888, pp. 347 et seq.
