360 people reported more than 1,700 cases. With few exceptions those who reported had had experience in teaching. 355 gave accounts of their own childish love affairs. The other five stated that they did not recall any such experience in their own lives. The 1,700 cases include the confessions. Added to the 800 cases of my own collection there are in all more than 2,500 cases that form the basis of this study. It will be seen that the syllabus calls for data of three kinds, viz., concerning (1) observed love between children of opposite sex about the same in age, (2) observed love between persons of opposite sex with disparity in ages, (3) personal confessions. The first two kinds of data were obtained by the objective method, while the last is obtained through retrospection. Having both observations and confessions many errors that could not otherwise be detected are eliminated since the two classes of material act, to a degree, as mutual controls. Each kind of data according to the first named classification has its particular virtue. The confessions (1) exhibit the continuity in the development of the emotion during the life-span of the individual as he sees it himself (enough cases (355) were given to make a reasonable allowance for individual variations); (2) they indicate the general prevalence of the emotion during childhood; (3) they reinforce observation in the same way that introspection always reinforces the objective method of study. In estimating the value of these confessions one must be mindful of the common defect of most auto-biographical statements, viz., that they are influenced by the almost irresistible tendency to write about one's self in a literary way and so touch plain facts as to make them less prosaic. The observations help us in eliminating this element of error. The data concerning the love that children have for adults of the opposite sex throw valuable light upon the nature of jealousy in children as it is much accentuated in these cases. They also show the effect of forcing the development of an emotion by a stimulus that is chronologically prior to the normal period of development. In the cases showing the love of the adult for a child are revealed facts bearing upon some forms of sexual perversion. In these cases the child is used as a means of escape for suppressed love. Love that normally should go out to an adult, is through some real or supposed necessity suppressed until it finally seeks quiescence through discharge upon a child or pet animal. This is not infrequent among women whose relatively passive role decreed by nature in love affairs has been exaggerated by society. The observations concerning love between children of opposite sex and about the same age aid us in determining the phase of the emotion's development that normally belongs to any given period of life; _i. e._, there are many observations upon children who are five years old, or six, seven,
