It is a notable fact in evidence of the close and seemingly normal association with the sexual impulse of the scatalogic processes, that an interest in them, arising naturally and spontaneously, is one of the most frequent channels by which the sexual impulse first manifests itself in young boys and girls. Stanley Hall, who has made special inquiries into the matter, remarks that in childhood the products of excretion by bladder and bowels are often objects of interest hardly less intense for a time than eating and drinking. ("Early Sense of Self," _American Journal of Psychology_, April, 1898, p. 361.) "Micturitional obscenities," the same writer observes again, "which our returns show to be so common before adolescence, culminate at 10 or 12, and seem to retreat into the background as sex phenomena appear." They are, he remarks, of two classes: "Fouling persons or things, secretly from adults, but openly with each other," and less often "ceremonial acts connected with the act or the product that almost suggest the scatalogical rites of savages, unfit for description here, but of great interest and importance." (G. Stanley Hall, _Adolescence_, vol. i, p. 116.) The nature of such scatalogical phenomena in childhood--which are often clearly the instinctive manifestations of an erotic symbolism--and their wide prevalence among both boys and girls, are very well illustrated in a narrative which I include in Appendix B, History II.
