Freud lays special stress upon infantile sexuality as it is manifested in the suckling and in the child. The infant brings with it into the world the germ of sexuality, which is, however, extremely difficult of comprehension since at this stage the sexual feelings are not directed towards other persons but are gratified on the child's own body in a manner which Havelock Ellis has termed "autoerotic." This autoerotic gratification is gained through erogenous zones, that is, certain areas of the body which are peculiarly sensitized to sexual excitations. Among these erogenous zones may be mentioned the mouth, lips, tongue, anal region, the neck of the bladder as well as various skin areas and sense organs. Already in 1879, Lindner, a Hungarian pediatrist, devoted a penetrating study to the sucking or pleasure-sucking of the child. Freud emphasizes that the suckling enjoys sexual pleasure, in the taking of nourishment, which it ever after seeks to procure by sucking independent of taking food. To many it may occasion surprise to learn that sucking is exhibited independently of its relation to the hunger instinct. It is, however, plain that the mouth is at first concerned only with the gratifying of the hunger instinct; later the desire for a repetition of pleasurable experience gained in this way is separated from the need of taking nourishment, thereby transforming this mucous surface into an erogenous zone. It is likewise difficult to conceive by the inexperienced in psychoanalysis, that the child derives pleasurable sensations from the anal zone. Because of the important rôle which anal eroticism plays in our case we might speak more fully of this form of autoeroticism. One not infrequently observes in little children that they refuse to empty the bowels when they are placed on the closet because they obtain pleasure from defecation, when the retained stool by its accumulation excites strong irritation of the mucosa. The importance which scatological rites and ceremonials, that is, certain peculiar niceties practiced in connection with the emptying of the bowels, play in the evolution of the race have been extensively discussed in literature. Havelock Ellis[7] says in this connection--"The most usual erotic symbolisms in childhood are those of the scatologic group, the significance of which has often been emphasized by Freud and his school. The channels of urination and defecation are so close to the sexual centers that the intimate connection between the two groups is easily understood. There is undoubtedly a connection between nocturnal enuresis and sexual activities, sometimes masturbation. Children not infrequently believe that the sexual acts of their elders have some connection with urination and defecation, and the mystery with which the excretory acts are surrounded, helps to support this theory. Up to puberty scatologic interests may be regarded as normal; at this age the child has still
