Note 511 — PART II THE PLAYFUL EXERCISE OF IMPULSES OF THE SECOND OR SOCIONOMIC358 ORDER (continued 3)

Altum, one of the highest authorities on birds, confirms this view (Der Vogel und sein Leben, fifth edition, Münster, 1875, p. 137). I have to thank Baldwin, too, for the reference to Guyau, who considers that the innate modesty may be “nécessaire à la femme pour arriver, sans se donner, jusqu’au complet développement de son organisme.” [See also Havelock Ellis, Geschlechtstrieb und Schamgefühl, p. 10. This view was worked out in some detail, it seems, together with a view of sexual selection similar to Professor Groos’s, by Hirn, in a chapter on Animal Display in a Swedish work in 1896: it is now reproduced in that author’s Origins of Art (1900), chap. xiv; cf. also the preface to the same work.—J.
