[236] “The sun,” says Grillparzer in his “Diary,” “is hostile to voluptuousness. But the artificial sun of our nocturnal illumination in our large town, has the opposite effect.”
[237] The old proverb says: “From the two V’s, Vinum (wine) and Venus (woman), there arises a big W, Weh (woe or pain).”
[238] Cf., in addition to the great works on the subject of alcohol, the special monograph by B. Laquer, “A Lecture on Alcohol and Sexual Hygiene,” published in the “Reports of the German Society for the Suppression of Venereal Diseases,” 1904, vol. ii., Nos. 3 and 4, pp. 56-63; W.

[239] It has been established by Bonhoeffer, Hoppe, A. H. Hübner, and others, that chronic alcoholism constitutes an important cause of prostitution in the case of the so-called “late prostitutes”—that is to say, in those women who do not commence a life of professional prostitution at puberty, but usually after the age of twenty-five years. Cf. Artur Hermann Hübner, “Prostitutes in Relation to Criminal Jurisdiction,” published in Monatsschr. für Kriminalpsychologie, edited by G. Aschaffenburg, 1907, p. 5.
[240] At the great public dinner which, in 1890, the town of Berlin gave in the Rathaus to the members of the International Medical Congress, and at which 4,000 persons consumed 15,382 bottles of wine, 22 hectolitres (484 gallons) of beer, and 300 bottles of brandy, there were witnessed in and outside the Rathaus the most disgusting scenes of drunkenness. “As the blowflies gather round a piece of carrion, so in the street in front of the Rathaus there had gathered a swarm of prostitutes, who found a rich booty among the drunken, staggering guests” (cf. Rosenfeld, op. cit., p. 325).—A striking example of the manner in which alcohol sometimes completely annihilates every æsthetic perception is reported by E. Kraepelin (“The Psychiatric Duties of the State,” p. 6; Jena, 1900): “A number of students were infected by a prostitute, who from early youth had been weak-minded, and who was suffering from both lupus of the nose and recent syphilis.”
