(2) good memory for facts and figures, 9 cases ; (3) good memory for form, 6 cases ; (4) good memory for names in natural history, 4 cases ; (5) good memory, no details, 5 cases ; (6) fitful and peculiar memory, 6 cases ; (7) bad memory, 7 cases. Total number of noteworthy cases, 43.

2. "After reading over a lecture or speech of an hour's duration, three times, can recollect nearly the words as written for 8 or 10 days."
