apparatus in us, what a wealth of motive would be lost!"[148] It is on the basis of this tonic influence of fear that in some morbidly sensitive natures fear acts as a sexual stimulant. Cullerre has brought together a number of cases in both men and women, mostly neurasthenic, in which fits of extreme anxiety and dread, sometimes of a religious character and often in highly moral people, terminate in spontaneous orgasm or in masturbation.[149] Professor Gurlitt mentions that his first full sexual emission took place in class at school, when he was absorbed in writing out the life of Aristides and very anxious lest he should not be able to complete it within the set time.[150] Dread and anxiety not only excite sexual emotion, but in the more extreme morbid cases they may suppress and replace it. Terror, say Fliess, is transmuted coitus, and Freud believes that the neurosis of anxiety always has a sexual cause, while Ballet, Capgras, Löwenfeld, and others, though not regarding a sexual traumatism as the only cause, still regard it as frequent. It is worthy of note that not only fear, but even so depressing an emotion as grief, may act as a sexual stimulant, more especially in women. This fact is not sufficiently recognized, though probably everyone can recall instances from his personal knowledge, such cases being generally regarded as inexplicable. It is, however, not more surprising that grief should be transformed into sexual emotion than that (as in a case recorded by Stanley Hall) it should manifest itself as anger. In any case we have to bear in mind the frequency of this psychological transformation in the presence of cases which might otherwise seem to call for a cynical interpretation. The case has been recorded of an English lady of good social position who fell in love with an undertaker at her father's funeral and insisted on marrying him. It is known that some men have been so abnormally excited by the funeral trappings of death that only in such surroundings have they been able to effect coitus. A case has been recorded of a physician of unimpeachable morality who was unable to attend funerals, even of his own relatives, on account of the sexual excitement thus aroused. Funerals, tragedies at the theater, pictures of martyrdom, scenes of execution, and trials at the law-courts have been grouped together as arousing pleasure in many people, especially women. (C.F. von Schlichtegroll, _Sacher-Masoch und der Masochismus_, pp. 30-31.) Wakes and similar festivals may here find their psychological basis, and funerals are an unquestionable source of enjoyment among some people, especially of so-called "Celtic" race. The stimulating reaction after funerals is well known to many, and Leigh Hunt refers to this (in his _Autobiography_) as affecting the sincerely devoted friends who had just cremated Shelley.
