Among the Indian men, it is deemed a mark of heroism to bear the most exquisite pain without complaining; upon this account they early inure themselves to burning part of their bodies with fire, or cutting them with sharp instruments. No young man can be admitted to the honours of manhood or war, who has not acquitted himself well in these trials of patience and fortitude. It is easy to conceive how much this contributes to give a tone to the nervous system, which renders it less subject to the occasional causes of diseases.
IV. We come now to speak of those customs which are common to both sexes: these are PAINTING, and the use of the COLD BATH. The practice of anointing the body with oil is common to the savages of all countries; in warm climates it is said to promote longevity, by checking excessive perspiration. The Indians generally use bear's grease mixed with a clay, which bears the greatest resemblance to the colour of their skins. This pigment serves to lessen the sensibility of the extremities of the nerves; it moreover fortifies them against the action of those exhalations, which we shall mention hereafter, as a considerable source of their diseases. The COLD BATH likewise fortifies the body, and renders it less subject to those diseases which arise from the extremes and vicissitudes of heat and cold. We shall speak hereafter of the Indian manner of using it.
It is a practice among the Indians never to drink before dinner, when they work or travel. Experience teaches, that filling the stomach with cold water in the forenoon, weakens the appetite, and makes the system more sensible of heat and fatigue.
The state of society among the Indians excludes the influence of most of those passions which disorder the body. The turbulent effects of anger are concealed in deep and lasting resentments. Envy and ambition are excluded by their equality of power and property. Nor is it necessary that the perfections of the whole sex should be ascribed to one, to induce them to marry. “The weakness of love (says Dr. Adam Smith) which is so much indulged in ages of humanity and politeness, is regarded among savages as the most unpardonable effeminacy. A young man would think himself disgraced for ever, if he showed the least preference of one woman above another, or did not express the most complete indifference, both about the time when, and the person to whom, he was to be married[5].” Thus are they exempted from those violent or lasting diseases, which accompany the several stages of such passions in both sexes among civilized nations.
It is remarkable that there are no deformed Indians. Some have suspected, from this circumstance, that they put their deformed children to death; but nature here acts the part of an unnatural mother. The severity of the Indian manners destroy them[6].
From a review of the customs of the Indians, we need not be surprised at the stateliness, regularity of features, and dignity of aspect by which they are characterized. Where we observe these among ourselves, there is always a presumption of their being accompanied with health, and a strong constitution. The circulation of the blood is more languid in the Indians, than in persons who are in the constant exercise of the habits of civilized life. Out of eight Indian men whose pulses I once examined at the wrists, I did not meet with one in whom the artery beat more than sixty strokes in a minute.
The marks of old age appear more early among Indian, than among civilized nations.
Having finished our inquiry into the physical customs of the Indians, we shall now proceed to inquire into their diseases.
A celebrated professor of anatomy has asserted, that we could not tell, by reasoning à priori, that the body was mortal, so intimately woven with its texture are the principles of life. Lord Bacon declares, that the only cause of death which is natural to man, is that from old age; and complains of the imperfection of physic, in not being able to guard the principle of life, until the whole of the oil that feeds it is consumed. We cannot as yet admit this proposition of our noble philosopher. In the inventory of the grave in every country, we find more of the spoils of youth and manhood than of age. This must be attributed to moral as well as physical causes.
