Hygienic management of the lymphatic and sanguine temperaments consists in the vigorous toning of the former, while restraint of the latter will greatly exempt it from the anxieties, contentions, and vexations which excite the mind, disturb the bodily functions, and end in chronic disease. People of the latter organization love mental and physical stimulants, are easily inflamed by passion, and their excitability degenerates into irritability, succeeded by serious functional derangements, which prematurely break down the individual with inveterate, deep-seated disorder. Serenity, hope, faith, as well as firmness, are natural hygienic elements. It is a duty we owe ourselves to promptly relinquish a business which corrodes with its cares, and depresses with its increasing troubles. Constant solicitude, and the apprehension of financial disaster, frustrate the bodily functions, disconcert the organic processes, and lead to mental aberration as well as physical degeneracy. Melancholy is chronic, while despair is acute mania, whose impulses drive the victim desperately toward self-destruction. The chronic derangement of these organs exerts with less force the same morbid tendency. Hence the necessity for exercising those hygienic and countervailing influences born of resolution, assurance, and confident trust, and the belief which strengthens all of the vital operations. Doubtless, this temperament is the source of the reproductive powers. It is the corner-stone essential to the foundation of all other temperaments. It has been supposed by some that the cerebellum is the seat of sexual instinct. The fact appears that an ample development of the posterior base of the cerebrum and the cerebellum indicates nutritive activity, which is certainly a condition most favorable to the display of amativeness. In a double sense, then, this temperament is a vital one; both by nutritive repletion, and by reproduction. It is the blood-manufacturing, tissue-generating, and body-constructing temperament, causing growth to exceed waste, and promptly repairing the wear which follows continual labor. While the sleazy structures of the lymphatic temperament are favorable to the functions of transudation, exhalation, and mutual diffusion of liquids, the sanguine, as its name indicates, is adapted to promote the circulation of the blood, to favor nutrition and reproduction. The former temperament does not move the world by its energies, or impress it vividly with its wisdom, and the latter is more enthusiastic, enjoyable, and quickening. Each temperament, however, possesses salient qualities and advantages. THE LIFE LINE.
