Note 34 — Chapter III · PLEASURE.

Dr. G. Dumas has made experiments on the condition of the circulation in states of joy and of sadness. He has attempted an experimental verification of Lange’s theory by showing that a definite condition of the circulation always accompanies various agreeable and painful emotions, and that “joy and sadness may thus be regarded as the mental reverberation of these circulatory conditions and their organic consequences.” See “Recherches expérimentales sur la Joie et la Tristesse,” Revue Philosophique, June-August 1896.—Ed.
