Casanova, Mémoires, vol. viii, pp. 74-76. Goncourt in his Journal, under date of April, 1862 (vol. ii, p. 27), tells a story of an Englishman who engaged a room overlooking a scaffold where a murderer was to be hanged, proposing to take a woman with him and to avail himself of the excitement aroused by the scene. This scheme was frustrated by the remission of the death penalty.
Alienist and Neurologist, May, 1907, p. 204.
This spectacle of the spider and the fly seems indeed to be specially apt to exert a sexual influence. I have heard of a precisely similar case in a man of intellectual distinction, and another in a lady who acknowledged to a feeling of "exquisite pleasure," on one occasion, at the mere sound of the death agony of a fly in a spider's web.
