    the existence of the greater number of cells and commis- sural fibres which the extra sensory and derivative func- tions above referred to would probably entail.^ Having considered some of the questions of * cerebral localization ’ relating to the production of Aphemia, Agraphia, and Aphasia, something must now be said in regard to the seat of lesions productive of the very varied conditions comprised under the term Amnesia. Our knowledge on this point is at present rather vague and indefinite, since it is only quite recently that the necessity of not confounding such cases with Aphasia has been at all generally recognized. Moreover, no distinct attempt has hitherto been made to analyze and classify the various conditions comprised under this one term * Amnesia.’ Much more will doubtless soon be ascer- tained, in reference to this subject, by future workers,’ especially when the examination of cases is more thoroughly and systematically undertaken.! Still the knowledge we possess of Amnesic conditions, as well as of the distribution of ‘ ingoing ’ fibres in their passage from the base of the Brain to the Convolutions, already enables us to point roughly to the neighbourhood in which lesions or injuries would be likely to produce defects of Speech and Writing of this type. Lesions of the convolutions about the posterior extremity * See also pp. 399-404. f In all cases of Amnesia, or of mixed Aphasia and Amnesia, details should among other things always be given in reference to the following points:—(1) The patient’s ability to iinderstand spoken words (not being deaf); (2) to repeat sounds or words when requested; (3) to write from dictation; (4) to understand and therefore to point out printed letters and words (not being blind); (5) to copy written words, or printed words into written words; and (6) to name printed letters or objects, or read aloud.
