While this description of the lymphatic temperament is correct, when illustrated by the civilized races of men who are accustomed to luxury, ease, and an abundance of food, it does not apply with equal accuracy to the cerebral organization of the American Indian. His skull, though broad at its anterior base, and high and wide at the cheek bones, differs from the European in being broader and longer behind the ears. Fig. 83 is an excellent representation of a noted North American Indian. While a great breadth of the base of the brain indicates morbid susceptibilities, yet these, in the Indian, are opposed by a superior height of the posterior part of the skull. Consequently, he is restless, impulsive, excitable, passionate, a wanderer upon the earth. The basilar faculties, however, are large, and he is noted for instinctive intelligence. His habits alternate from laziness to heroic effort, from idleness and quiet to the fierce excitement of the chase, from vagabondism to war, sometimes indolent and at other times turbulent, but under all circumstances, irregular and unreliable. In this case, lacteal activity is greater than lymphatic, as his nomadic life indicates. Nevertheless, he manifests a morbid sensibility to epidemic diseases, especially those which engender nutritive disorders and corrupt the blood. Figs. 84 and 85 represent the brain of an American Indian, and that of a European, and show the remarkable difference in their anatomical configuration. Evidently it is a race-distinction. Observe the greater breadth of the brain of the Indian, which according to cerebral physiology indicates great alimentiveness, indolence, morbid sensibility, irritability, profligacy, but also note that it _differs materially in the proportion of all its parts_, from the European brain. Judging the character of the Indian from the aforesaid representation, we should say that he was cunning, excitable, treacherous, fitful, taciturn, or violently demonstrative. His constitution is very susceptible to diseases of the bowels and blood. His appetite is ungovernable, and his love of stimulants is strong. Syphilitic poison, small-pox, and strong drink will annihilate all these tribes sooner than gunpowder. Their physical traits of constitution are no less contradictory than their extremes of habit and character, for while there is evidence of _lymphatic elements_, yet it is contradicted by the color of the hair, eyes, and skin. This peculiar organization will not blend in healthful harmony with that of the European, and this demonstrates that the race-temperaments require separate and careful analytical consideration.
