Note 9 — Chapter III

I adopt this distinction from Dr. J. Hughlings Jackson. See his articles, "On Affections of Speech from Diseases of the Brain," in Brain, Nos. iii. and vii. The second stage might conveniently be named apperception, but for the special philosophical associations of the term: Problems of Life and Mind, third series, p. 107. This writer employs the word "preperception" to denote this effect of previous perception.
