their swearing is this: they set a sheep in the midst of them, and rub it over with butter, the heads of families who are the chief in the nation lay their hands upon the head of the sheep, and swear to observe their promise. This oath (which they never violate) they explain thus: the sheep is the mother of them who swear; the butter betokens the love between the mother and the children, and an oath taken on a mother's head is sacred. Upon the security of this oath, I made them acquainted with my intention, an intention, they told me, it was impossible to put in execution. From the moment I left them they said they could give me no assurance of either life or liberty, that they were perfectly informed both of the roads and inhabitants, that there were no fewer than nine nations between us and Abyssinia, who were always embroiled amongst themselves, or at war with the Abyssins, and enjoyed no security even in their own territories. We were now convinced that our enterprise was impracticable, and that to hazard ourselves amidst so many insurmountable difficulties would be to tempt Providence; despairing, therefore, that I should ever come this way to Abyssinia, I resolved to return back with my intelligence to my companion, whom I had left at Pate. I cannot, however, leave this country without giving an account of their manner of blood-letting, which I was led to the knowledge of by a violent fever, which threatened to put an end to my life and travels together. The distress I was in may easily be imagined, being entirely destitute of everything necessary. I had resolved to let myself blood, though I was altogether a stranger to the manner of doing it, and had no lancet, but my companions hearing of a surgeon of reputation in the place, went and brought him. I saw, with the utmost surprise, an old Moor enter my chamber, with a kind of small dagger, all over rusty, and a mallet in his hand, and three cups of horn about half a foot long. I started, and asked what he wanted. He told me to bleed me; and when I had given him leave, uncovering my side, applied one of his horn cups, which he stopped with chewed paper, and by that means made it stick fast; in the same manner he fixed on the other two, and fell to sharpening his instrument, assuring me that he would give me no pain. He then took off his cups, and gave in each place a stroke with his poignard, which was followed by a stream of blood. He applied his cups several times, and every time struck his lancet into the same place; having drawn away a large quantity of blood, he healed the orifices with three lumps of tallow. I know not whether to attribute my cure to bleeding or my fear, but I had from that time no return of my fever.
