In the first, the recollections detached from memory are arbitrarily and even capriciously chosen: they may be certain words, certain figures, or often all the words of an acquired language. In the second, the disappearance of the words is governed by a methodical and grammatical order, that which is indicated by Ribot's law: proper names go first, then common nouns, and lastly verbs.[1] Such are the external differences. Now this, I believe, is the internal difference. In the amnesias of the first type, which are nearly always the result of a violent shock, I incline to think that the memories which are apparently destroyed are really present, and not only present but acting. To take an example frequently borrowed from Forbes Winslow,[2] that of a patient who had forgotten the letter F, and the letter F only, I wonder how it is possible to subtract a given letter wherever met with,—to detach it, that is, from the spoken or written words in which it occurs,—if it were not first implicitly recognized.
