Suckling still belongs to the function of nutrition, but passes beyond it, however, in that it is no longer the function of nutrition, but rhythmic activity, with pleasure and satisfaction as a goal, without the taking of nourishment.

In the period of the displaced rhythmic activity the hand appears still more clearly as an auxiliary organ; the gaining of pleasure leaves the mouth zone and turns to other regions. The possibilities are now many. As a rule, other openings of the body become the objects of the libido interest; then the skin, and special portions of that. The activity expressed in these parts, which can appear as rubbing, boring, picking, and so on, follows a certain rhythm and serves to produce pleasure. After longer or shorter tarryings of the libido at these stations, it passes onward until it reaches the sexual zone, and there, for the first time, can be occasion for the beginning of onanistic attempts. In its migration the libido takes more than a little of the function of nutrition with it into the sexual zone, which readily accounts for the numerous and innate correlations between the functions of nutrition and sexuality. If, after the occupation of the sexual zone, an obstacle arises against the present form of application of the libido, then there occurs, according to the well-known laws, a regression to the nearest station lying behind, to the two above-mentioned periods. It is now of special importance that the epoch of the displaced rhythmic activity coincides in a general way with the time of the development of the mind and of speech. I might designate the period from birth until the occupation of the sexual zone as the pre-
