noble, moral faculties--Faith, Love, and Devotion--and, whenever temptation inordinately allures, the course of life is likely to be characterized by dishonorable, deceptive, and treacherous conduct. The pangs of hunger cause soldiers to act more like ravenous beasts, than rational beings. It is animal instinct which impels the soldier to seek first for the gratification of his appetite. Some persons, instigated by carnivorous desires, yearn for raw meat, and will not be satisfied unless their food is flavored with the flesh of animals. Their bodies increase and thrive, even to repletion. Contrast these individuals with pale, lean, anæmic people, who crave innutritious articles of diet, and eat soft stones, slate, chalk, blue clay, and soft coal. Such perversions of the appetite are manifested only when there is either a diminution in the volume of blood, deficient alimentation, defective assimilation, or a general depravity of the nutritive functions. Morbid conditions generate vitiating tendencies and destroy the natural appetite. While alcoholic stimulants affect the medulla oblongata principally, opium acts chiefly on the cerebrum, and excites reverie, dreamy ideality, optical delusions, and the creative powers of the imagination; some of these hallucinations are said to be grotesquely beautiful and enjoyable. The effects of this agent differ from those of alcoholic intoxication by not deadening the moral sensibilities, or arousing the animal propensities. Opium smokers are dreamy and abstracted, not quarrelsome or violent. Those who use ardent spirits lose their moral delicacy, their intellect becomes dull, the reason cloudy, and the judgment is overruled by appetite. It is conceded that the _trophic center_ is principally in the medulla oblongata; the cerebellum and lower cerebral ganglia, however, favorably influence the nutritive functions, and, when these organs are large and active, a plethoric condition is the natural consequence. Redundancy of blood in the body indicates preponderance of the basilar organs. These faculties being vehement in character, an excess of animal characteristics produces those conditions which result in acute and inflammatory diseases. We may express these conditions of the system as follows: The _Animal Faculties_ correspond to the lower instinctive manifestations. / ACQUISITIVENESS, The elements of character are { SELFISHNESS, \ COMBATIVENESS They tend to / TURBULENCE, \ CRIME. / ALIMENTATION, They relate especially to the { SECRETION, functions of \ NUTRITION, \ REPRODUCTION. / VITALITY, A large development of them { PLETHORA, indicates \ HYPERAEMIA (congestion).
