The ear, it is well known, is very sensitive to vasomotor changes, slight changes serving to affect the circulation visibly; so that in pale, nervous people a trifling emotion will cause the ears to blush. Galton tells us of a schoolmistress who judges of the fatigue of her pupils by the condition of their ears. If the ears are white, flabby, and pendent, she concludes that the children are very fatigued; if they are relaxed but red, that they are suffering, not from overwork, but from a struggle with their nervous systems, rarely under control at the age of fourteen or fifteen. If this kind of sensitiveness is not common among criminals, a few of neurotic temperament, as well as some lunatics, possess the power, rare among normal persons, of moving the ear. Frigerio notes movements of the superior and posterior muscles, especially when touched; in apes the transverse muscle also acts. Frigerio connects this power of movement with perpetual fear, always on the look-out; many of the criminals with this peculiarity were recidivists, and three of the lunatics had delusions of persecution. The interest of these investigations, now so actively carried on, into the malformations of the pinna among criminals is obvious. A few ingenious persons have sought to explain some of them by the influence of the headgear, pulling of the ears, etc.; but on the whole it is generally recognised that they are congenital. The study of them, therefore, is of distinct value in enabling us to fix the natural relationships of the criminal man. There is still need for careful series of observations on criminals, the insane, epileptics, and idiots, and every such series should be controlled by a similar series of observations, by the same observer, on ordinary subjects. The criminal nose has been measured and studied with great care and enthusiasm by Ottolenghi.[25] He finds that the criminal nose in general is rectilinear, more rarely undulating, with horizontal base, of medium length, rather large and frequently deviating to one side, and he describes several varieties. Thus the typical thief’s nose is rectilinear, often incurved, short, large, and often twisted, with lifted base. The sexual offender presents the most rectilinear nose, though he shows the undulating profile of nose more frequently than any other group of criminals, of medium length and rather large. Ottolenghi believes that his observations help to show, both in the skeleton and in life, an anatomical relationship between criminals against the person and epileptics and monomaniacs; also a relationship between thieves and sexual offenders and cretins. His observations are full and interesting, but the matter needs further investigation; the anthropological importance of the nose has scarcely yet been fully realised.
