Let others write of the other Americans to whom and what they choose: I shall not contradict them. Of the Paraguayrians I confidently affirm that the equestrian nations greatly excel the pedestrians in beauty of form, loftiness of stature, strength, health, and longevity. The bodies of the Abipones are muscular, robust, agile, and extremely tolerant of the inclemencies of the sky. You scarcely ever see a fat or pot-bellied person amongst them. Daily exercise in riding, hunting, and in sportive and serious contests prevents them almost always from growing fat, for like apes they are always in motion. They consequently enjoy such an excellent habit of body, and such sound health as most Europeans might envy. Many diseases which afflict and exhaust Europeans are not even known by name amongst them. Gout, dropsy, epilepsy, jaundice, stone, &c. are words foreign and monstrous to their ears. They expose their bare heads for whole days to the heat of the sun, and yet you never hear one of them complain of head-ache. You would swear they were devoid of feeling, or made of brass or marble; yet even these grow hot when acted on by the rays of the sun. After having been long parched with thirst in dry deserts, they drink large draughts of marshy, salt, muddy, stinking, bitter water, without injury. They greedily swallow quantities of hard, half-roasted beef, venison, tiger's and emu's flesh, and the eggs of the latter, without experiencing any consequent languor of the stomach, or difficulty of digestion. They often swim across vast rivers in cold rainy weather without contracting any ill affection of the bowels or bladder, which was often troublesome to the Europeans in swimming, and, if succeeded by strangury, dangerous. They ride seated on saddles made of hard leather during journeys of many weeks, and yet such long sitting does not injure the external skin even. They are unprovided with stirrups, and often use trotting horses, yet after many hours of uninterrupted riding you can perceive no signs of fatigue or exhaustion in any of them. Stretched on a cold turf, should a sudden shower descend, they pass the night swimming in water, yet never know what the colic or the gout is. The Spaniards run the risk of both after being long drenched with rain water, which, when it touches the skin, affects the body most terribly in America, often producing syncope, and sometimes pustules and ulcers. I have frequently seen Spanish soldiers faint in the church from having been wetted with rain on their way thither. The Abipones pass many days and nights amid constant rain uninjured, because their feet are bare; for the moisture contracted from rain hurts the feet when they are wrapt up more than when they are uncovered; as, finding no vent when it exhales, it creeps inwards, penetrates the bones and nerves, and affects the rest of the body in a terrible manner. But I can give you further proof of the strength of the Abipones.
