If the efforts which children make for liberty, when confined in the swaddling-clothes, are hurtful, the inaction in which they are held by it, is perhaps still more so. Want of exercise naturally retards the growth of their limbs, and diminishes the strength of their bodies; and of consequence such children as enjoy the liberty of moving at pleasure, must be the most vigorous. It was for this reason that the ancient Peruvians gave their infants the full freedom of their arms in a swathing-bag; afterwards, as their children grew, they put them up to the middle in a hole dug in the earth, and lined with linen; by this method they had their arms free, and could move their heads and bend their bodies, without falling or hurting themselves. So soon as they were able to step, they were presented with the breast, at a little distance, as an incentive for them to walk. The children of Negroes are often exposed to much greater fatigues, in order to come at the nipple, they cling round one of their mother's haunches with their legs, and support themselves without any assistance from her; seizing the breast they continue to suck in perfect safety, notwithstanding she is all the while in motion, or at work. These children begin to walk, or rather creep on their knees and hands, in the second month; and this exercise qualities them for running afterwards in this manner, almost as nimble as they do upon their feet. _END OF THE THIRD VOLUME._ T.
