[68]. Lange’s book On the Emotions first appeared in Danish, and has been translated into German (1887) by Dr. Kurella, and into French (1895) by Dr. G. Dumas. W. James first explained his theory in an article in Mind (1884), and subsequently in his Principles of Psychology (1890), vol. ii. chap. xxv.

Since the publication of James’s book, Dr. Berkeley has reported, in Brain (iv. 1892), two cases of general anæsthesia, cutaneous and sensory: the subjects are apathetic, but the presence of shame, sorrow, surprise, fear, and repulsion (the last-named as a substitute for anger) has been observed. Dr. Sollier, in an article in the Revue Philosophique (March, 1894), has reported some experiments made on subjects in a profoundly hypnotic state, in whom the peripheral and visceral sensibility had been abolished by suggestion. He comes to the same conclusions as James and Lange.
