"secondary
homosexuality."

[130] See, for instance, Hirschfeld's reasonable discussion of the matter,
_Die Homosexualitaet_, ch. xvii.

[131] Alfred Fuchs, who edited Krafft-Ebing's _Psychopathia Sexualis_
after the latter's death, distinguishes between congenital homosexuality,
manifesting itself from the first without external stimulation, and
homosexuality on a basis of inborn disposition needing special external
influences to arouse it (_Jahrbuch fuer sexuelle Zwischenstufen_, Bd. iv,
1902, p. 181).

[132] Krafft-Ebing, "Ueber tardive Homosexualitaet," _Jahrbuch fuer
sexuelle Zwischenstufen_, Bd. iii, 1901, p. 7; Naecke, "Probleme auf
den Gebiete der Homosexualitaet," _Allgemeine Zeitschrift fuer
Psychiatrie_, 1902, p. 805; ib., "Ueber tardive Homosexualitaet,"
_Sexual-Probleme_, September, 1911. Numa Praetorius (_Jahrbuch fuer
sexuelle Zwischenstufen_, January, 1913, p. 228) considers that
retarded cases should not be regarded as bisexual, but as genuine
inverts who had acquired a pseudoheterosexuality which at last falls
away; at the most, he believes such cases merely represent a
prolongation of the youthful undifferentiated period.

[135] This was the term used in the earlier editions of the present
_Study_. I willingly reject it in favor of the simpler and fairly clear
term now more generally employed. It is true that by bisexuality it is
possible to understand not only the double direction of the sexual
instinct, but also the presence of both sexes in the same individual,
which in French is more accurately distinguished as "bisexuation."

[136] J. Van Biervliet, "L'Homme Droit et l'Homme Gauche," _Revue
Philosophique_, October, 1901. It is here shown that in the constitution
of their nervous system the ambidextrous are demonstrably left-sided
persons; their optic, acoustic, olfactory, and muscular sensitivity is
preponderant on the left side.
