[540] We owe to Näcke the recognition of the importance of sexual dreams in the diagnosis of homosexuality and heterosexuality. Cf. his essay, “The Forensic Significance of Dreams,” published in the Archives for Criminal Anthropology, 1889, vol. iii.; also P. Näcke, “The Dream as the Most Delicate Reagent for the Detection of the Mode of Sexual Sensibility,” published in the Annual Review of Criminal Psychology, 1905.

[542] The description of this interesting scene, with other details regarding the organization of the homosexuals of Paris, is found in the work of Pisanus Fraxi (Henry Spencer Ashbee). “Centuria Librorum Absconditorum,” pp. 406-416 (London, 1879) (based upon personal reports by Paul Lacroix).

[544] There are also numerous places of public resort which are indeed largely attended by urnings, but are also frequented by heterosexuals.
