boy will often take out twenty or more worms, and when your fingers and nails are almost all filled with holes, and the soles of your feet so lacerated as to prevent you from walking a step without difficulty, you will yourself deplore your neglect and procrastination. I have known many persons confined to their beds for weeks, and others entirely deprived of the use of their feet on this account. Though these worms chiefly attack the feet, yet they sometimes, with still greater danger, creep to the other parts of the body, and make their nest in the arm or knee. Dogs, from their always lying on the ground, are most troubled with these insects; but they dexterously remove them from their flesh with their tongues, and heal the wound by licking it. Sows, tame monkeys, cats, goats, and sheep, are dreadfully tormented by them; but horses, asses, mules, and oxen, are protected against the common enemy by the hardness of their hoofs. The Americans should take care to fill up the hollow left by the bladder with tobacco-powder, ashes, or soap, otherwise the wound made by the needle, and infected with the poison of the insect, will become ulcerous, conceive matter, and, on occasion of inflammation, or violent motion of the feet, will end in a gangrene, or St. Anthony's fire. Hen's fat and a cabbage leaf applied to the feet, to allay the inflammation, have often been found of service. They write that the Brazilians, to keep off these worms, anoint their feet with an oil expressed from the unripe acorns of the acaju. Sailors daub themselves with pitch for the same purpose. All of us, in the fear of these and other insects, wore sheepskin leggings, but we found them weak and inefficient defences.
