Note 88 — Chapter VII

See case No. 51, later; and compare Mr. Galton's observations in his lecture at the Royal Institution on "The Just Perceptible Difference" (reported in the Times, January 30th, 1893). Mr. Galton found that the ideal auditory impressions called up by reading the printed substance of a lecture enabled him to hear the lecturer's voice at a greater distance than when he had not the printed text before him; the ideal appears to have supplemented the real impression, as, in the case given in the text, the real reinforced the ideal.
