This certainly looks like stimulation, but on comparing it with other instances of abnormal reminiscence differently caused, we shall find reason for believing that it is nothing of the kind. There is no doubt that insanity may in the most general way be described as a species of cerebral paralysis, yet in many kinds of insanity there is an abnormal quickening of memory. Likewise in idiocy, which differs from insanity as being due to arrested development rather than to degradation of the cerebrum, the same phænomenon is sometimes witnessed. We remember seeing a child who, though generally considered quite "foolish," could, as we were assured, accurately repeat large portions of each Sunday's sermon. Dr. Anstie mentions a boy, absolutely idiotic, who nevertheless "had a perfect memory for the history of all the farm animals in the neighbourhood, and could tell with unerring precision that this was So-and-so's sheep or pig among any number of other animals of the same kind." Similar phænomena have been observed in epileptic delirium, and in the delirium of fevers. Every one has heard Coleridge's story of the sick servant-girl who repeated passages from Latin, Greek and Hebrew authors which she had years before heard recited by a clergyman in whose house she worked. A gentleman in India, after a sunstroke, utterly lost his command of the Hindustani language, recovering it only during the recurrent paroxysms of epileptic delirium to which he was afterward subject. Equally interesting is the case of the Countess de Laval, who in the ravings of puerperal delirium was heard by her Breton nurse talking baby-talk to herself in the Breton language,--a language which she had known in early infancy, but had since so entirely forgotten as not to distinguish it from gibberish when spoken before her.[6] A similar exaltation of memory not unfrequently precedes the coma produced by chloroform; and it has been known to occur in cases of acute poisoning by opium and haschisch. Finally it may be observed that drowning men are said to recall, as in a panoramic vision, all the events of their lives, even the most trivial. [6] For this and parallel cases see Hamilton, _Lectures on Metaphysics_, Lect. XVIII. We may conclude therefore that the extraordinary memory sometimes observed in drunken persons, however obscure the interpretation of it may at present be, is at all events a symptom, not of mental exaltation, but of mental disorganization consequent upon cerebral disease. We may search in vain among the phænomena of intoxication for any genuine evidences of that heightened mental activity which is said to be followed by a depressive recoil. There is no recoil; there is no stimulation; there is nothing but paralytic disorder from the moment that narcosis begins. From the outset the whole nervous system is lowered in tone, the even course of its nutrition disturbed, and the rhythmic discharge of its functions interfered with.
