Upon looking at this worm, on its first appearance, a small black head is extremely visible, with a hooked beak of a whitish colour. Its body is seemingly of a white silky texture, very like a small tendon bared and perfectly cleaned. After its appearance the natives of these countries, who are used to it, seize it gently by the head, and wrap it round a thin piece of silk or small bird’s feather. Every day, or several times a-day, they try to wind it up upon the quill as far as it comes readily; and, upon the smallest resistance, they give over for fear of breaking it. I have seen five feet, or something more of this extraordinary animal, winded out with invincible patience in the course of three weeks. No inflammation then remained, and scarcely any redness round the edges of the aperture, only a small quantity of lymph appeared in the hole or puncture, which scarcely issued out upon pressing. In three days it was commonly well, and left no scar or dimple implying loss of substance. I myself experienced this complaint. I was reading upon a sofa at Cairo, a few days after my return from Upper Egypt, when I felt in the fore part of my leg, upon the bone, about seven inches below the center of my knee-pan, an itching resembling what follows the bite of a muscheto. Upon scratching, a small tumour appeared very like a muscheto bite. The itching returned in about an hour afterwards; and, being more intent upon my reading than my leg, I scratched it till the blood came. I soon after observed something like a black spot, which had already risen considerably above the surface of the skin. All medicine proved useless; and the disease not being known at Cairo, there was nothing for it but to have recourse to the only received manner of treating it in this country. About three inches of the worm was winded out upon a piece of raw silk in the first week, without pain or fever: but it was broken afterwards through the carelessness and rashness of the surgeon when changing a poultice on board the ship in which I returned to France: a violent inflammation followed; the leg swelled so as to scarce leave appearance of knee or ancle; the skin, red and distended, seemed glazed like a mirror. The wound was now healed, and discharged nothing; and there was every appearance of mortification coming on. The great care and attention procured me in the lazaretto at Marseilles, by a nation always foremost in the acts of humanity to strangers, and the attention and skill of the surgeon, recovered me from this troublesome complaint.
