Reading edition
After this chapter was first published (in the Centralblatt für Nervenheilkunde, February, 1896), Féré also compared congenital inversion to color-blindness and similar anomalies (Féré, "La Descendance d'un Inverti," Revue Générale de Clinique et Thérapeutique, 1896), while Ribot referred to the analogy with color-hearing (Psychology of the Emotions, part ii, ch. vii).
