A grinning expression and the protrusion of the lips appear sometimes to go together. A close observer says that he has seen many instances of intense hatred (which can hardly be distinguished from rage, more or less suppressed) in Orientals, and once in an elderly English woman. In all these cases there “was a grin, not a scowl—the lips lengthening, the cheeks settling downwards, the eyes half-closed, whilst the brow remained perfectly calm.”[1011] This retraction of the lips and uncovering of the teeth during paroxysms of rage, as if to bite the offender, is so remarkable, considering how seldom the teeth are used by men in fighting, that I inquired from Dr. J. Crichton Browne whether the habit was common in the insane whose passions are unbridled. He informs me that he has repeatedly observed it both with the insane and idiotic, and has given me the following illustrations:— Shortly before receiving my letter, he witnessed an uncontrollable outbreak of anger and delusive jealousy in an insane lady. At first she vituperated her husband, and whilst doing so foamed at the mouth. Next she approached close to him with compressed lips, and a virulent set frown. Then she drew back her lips, especially the corners of the upper lip, and showed her teeth, at the same time aiming a vicious blow at him. A second case is that of an old soldier, who, when he is requested to conform to the rules of the establishment, gives way to discontent, terminating in fury. He commonly begins by asking Dr. Browne whether he is not ashamed to treat him in such a manner. He then swears and blasphemes, paces tip and down, tosses his arms wildly about, and menaces any one near him. At last, as his exasperation culminates, he rushes up towards Dr. Browne with a peculiar sidelong movement, shaking his doubled fist, and threatening destruction. Then his upper lip may be seen to be raised, especially at the corners, so that his huge canine teeth are exhibited. He hisses forth his curses through his set teeth, and his whole expression assumes the character of extreme ferocity. A similar description is applicable to another man, excepting that he generally foams at the mouth and spits, dancing and jumping about in a strange rapid manner, shrieking out his maledictions in a shrill falsetto voice.
