The anatomic architecture of the latter thymo-centric personality is fairly typical. The reversion in type of the reproductive organs, the slender waist, the gracefully formed body, the rounded limbs, the long chest and the feminine pelvis strike one at the first glance. The texture of the skin is smooth as a baby's, and sometimes velvety to the touch. Its color may be an opaque white, or faintly creamy, or there may be an effect of a filmy sheen over a florid complexion. Little or no hair on the face contributes to the general feminine aspect in the more extreme types. They are often double jointed somewhere, flat footed, knock-kneed. In women, the external manifestations of a thymo-centric personality may be limited to thinness and delicacy of the skin, narrow waist, rather poorly developed breasts, arched thighs and scanty hair, with scanty and delayed menstruation. Or there may be obesity, with juvenility, if there is a repression of the pituitary secretion for one reason or other. In their reactions to the problems, physical and psychic, of everyday life, the thymo-centrics are distinctly at a disadvantage. In the first place, muscular strain, stress or shock is dangerous to them because they have a small heart, and remarkably fragile blood vessels, which renders their circulation incapable of responding to an emergency, or at least definitely handicapped. In infancy, they may die suddenly because of this, either for no ascertainable cause at all, or because of some slight excitement like that attending some slight operation, a fall, or a mild illness. During the run-about epoch they are unable to cope with the necessities of an active child's existence in playing with other children. Puberty and adolescence are specially perilous to them for they may endeavour to compensate for an inner feeling of physical inferiority by going in strenuously for athletics and sports, and so risking a sudden hemorrhage in the brain, producible by the tearing of a blood vessel, as if constructed of defective rubber. Reports published in the newspapers from time to time of children or young men instantly killed by a tap on the jaw in a boxing contest, or some other trivial injuries are doubtless samples of such reactions in thymo-centric people. As an illustration of the conduct aberrations of the thymo-centric personality during adult life, the following extracts from a newspaper report of a suicide are worth quoting. "An autopsy made yesterday by Dr. Benjamin Schwartz, first assistant to Dr. Charles Norris, Chief Medical Examiner, removed any mystery that surrounded the death on Saturday night by pistol bullets of Dr. José A. Arenas and the wounding of 'Miss Ruth Jackson' and Ignatio Marti. "Dr. Schwartz said that his post-mortem examination had convinced him beyond doubt that the dead physician-dentist had killed himself after he had tried to take the life of the young woman with whom he had lived and of the youth who was his successful rival.
