The impairment of the sense of right and wrong becomes quite marked; the patient loses the sense of property and ownership. In no other disease could the reported case occur of a man, to outward appearance well, going up to a policeman and asking his assistance in rolling off a barrel {191} of liquor which belonged to some one else, and which he meant to appropriate. For this reason what seem to be thefts are very common, and although by that time there is striking mental impairment, it may not be obvious to every-day people. Almost every other moral obliquity occurs, particularly a tendency to drunkenness and every possible violation of the proprieties and laws regarding property and the sexual function. It is all done, too, in such a foolish way that the insanity would be apparent to almost any intelligent person before whom the facts might be fully and clearly placed. There may be a curious consciousness in the patient of the fact that something is the matter with him, and a most extraordinary unconsciousness of what an inordinate fool he is acting. If he can be made to see what folly he is committing, perhaps a few moments later he is saying that he was n-ever b-better in his life. The emotions change most rapidly, and an adroit examiner will have his patient crying over some trifle one moment, and another moment laughing over something equally inconsequent. The prevailing mental state changes as rapidly as the emotions. Violent anger, outbursts of passion, penitence, amusement do not succeed each other more rapidly than indifference, melancholy, and exaltation. The suicidal idea is common in general paralytics before they become very demented; the suicidal impulse is rarely strong enough to result in anything more than futile attempts at self-destruction. Suicide by deliberation is also rare, for even when it is meditated the weakened, indecisive mind usually fails to prepare adequate plans for its successful issue. Homicidal attempts are not to be expected as a rule, except in the delirium of the states of maniacal excitement or in an outburst of anger for a fancied wrong or deliberately for some trifling reason. Even from suicide and homicide a practised physician or attendant will easily turn the general paralytic who is not maniacal to some amusing or silly thought. He has become credulous, simple-minded, and easily moulded to an expert's wishes, so far as his general conduct is concerned, and yet at any moment he is capable of a furious mania or a violent storm of passion, which after cerebral congestive attacks may be long and severe. Sometimes these symptoms just described may be very pronounced at night and not especially troublesome during the daytime. I have had patients who were dangerous, violent, noisy, deluded at night, and entirely quiet by day, for several months.
