But these characteristics are not confined to the nutritive system: they extend to the thinking one. The attention is not continuous; the perceptions succeed with some difficulty; the memory is not to be trusted; the imagination is weak; and the propensities, the appetites, and the passions, are so languid, as to be scarcely capable of troubling the quietude and the indolence which depend on such a constitution.
These characteristics of the phlegmatic temperament, present to us forms more rounded and less expressive, a general softness, a feeble color of the skin, a sort of etiolation, a pale countenance, a light and abundant hair, and, generally, an insurmountable inclination to sloth, averse alike to labors of the mind and body.
It has been observed, that the sanguine temperament, so generally met with among northern nations, is the necessary consequence of the continual and very energetic reaction of the powers of circulation, against the effects of external cold; that it is only by the constant activity of the heart and vessels that calorification can be effected with the necessary vigor: and that the effects of this redoubled action are the same to the organs of circulation as to the muscles, under the influence of volition; exertion in both increasing the power of the organs exerted.
In the sanguine temperament, the lymphatic, circulating, and secreting systems appear to be in a sort of equilibrium; the chest is larger, and the lungs more voluminous; the circulation is more rapid, the arterial predominance is obvious; the pulse is sharp, frequent, and regular; the complexion is ruddy; all the vital actions are extremely easy; and the health is rarely altered.
The mental functions correspond. The conception is quick; the memory is prompt; the imagination is lively; the judgment has more readiness than depth and extent; the mind, easily affected by the impressions of outward objects, passes rapidly from one idea to another; the tastes, propensities, appetites, passions, are equally ephemeral; and there is much activity, but the strength is soon exhausted.
In persons of this temperament, the countenance is animated; the hair is fair, and inclining to chestnut; the shape is good; the form is softened, though distinct; and the muscles are of tolerable consistence, and moderate development. The whole appearance is generally so amiable, that this temperament may be called that of health, beauty, and happiness.
In the women who present the attributes of their sex with the greatest unity, we distinguish, especially during youth and adult age, the traits of the sanguine temperament, which may be regarded as the most suitable to the organization of woman.
