These are the marks of an unusually warm heart: largeness of respiration, quickness and density of pulse, boldness and maniacal ferocity, the chest is covered with hair, particularly the breast, and usually the parts of the hypochondriac regions adjoining to it; and the whole body is hot, unless the liver powerfully antagonise. And capacity of chest is also a mark of heat, unless the brain in that case antagonise. But an unusually cold heart has the pulse smaller than moderate, and such persons are timid and spiritless, more especially if there be no hairs on the breast. Dryness of the heart renders the pulse hard, and the passions ungovernable, fierce, and difficult to quell; and, for the most part, the whole body is drier than usual, unless the parts about the liver antagonise. These are the marks of a more humid temperament: a soft pulse, a disposition easily roused to anger, and easily pacified, and the whole body more humid than common, unless antagonised by the parts about the liver. When the temperament is both hotter and drier, the pulse is large, hard, and quick and dense; and the respirations large, quick, and dense. And of all others such persons have the most hair upon the breast and præcordia; they are prone to action, given to anger, fierce and tyrannical in their dispositions; for they are both passionate and implacable. But, if humidity prevails with heat, such persons are less covered with hair than the afore-mentioned; they are prompt to action, their disposition is not fierce, but only prone to anger; their pulse is large, soft, quick, and dense. But when the temperament is more humid and cold than common, the pulse is soft, the disposition spiritless, timid and sluggish; they have no hair on the breast, and neither indulge in lasting resentment, nor are prone to anger. A cold and dry heart renders the pulse harder and small. Of all others, such persons are least given to anger, but when provoked they retain their resentment. They are also particularly distinguished by having no hair on the breast. * * * * *
