"When a part of the English troops," he continued, "marched from India, to co-operate with our army in Egypt, I eagerly seized the opportunity thus offered of visiting in safety several interesting countries, which I might never again have the means of seeing. I easily obtained permission to accompany the army, and set out as upon a party of pleasure; but before our landing, I was seized with a violent fever; and all that my friend Colonel M---- could do for me, was to leave me in charge of a respectable Arab, at Cossier, while the army pursued its march towards the Nile. I need not repeat all that has been said upon Arab hospitality; it is a well known fact, that the highest degree of that virtue is to be found amongst a people, the business of whose life is rapine and plunder. But my host was of a very superior description: and having broken bread and eaten salt together, I was, as he expressed himself, his brother, and truly as a brother, did he treat me. He was a merchant, carrying on a considerable trade in gums and spices, and every year he made a journey into Egypt, where the luxury of the Mamelukes offered a ready mart for his merchandize. It wanted but a short time to his annual expedition, and when I had recovered from my illness, I was glad enough to wait a few weeks, till such time as I could cross the desert under the protection of his escort. When the time for our departure arrived, we sat out, guarded by a tribe of the Arabs of the desert, whom my friend and his companions hired as a protection to their caravan. On our journey, as there was not water wherewith to perform the ablutions prescribed by the Mahommedan religion, the dry sand of the desert was used as a substitute; and observing my host, or, as I may call him, my protector, for such indeed he was on every occasion, I remarked, that with particular prayers, he took care to bare his arms, and rub the sand from the tip of his little finger to the joint of the elbow; but what most attracted my curiosity, was the appearance of a leathern thong, serving to bind upon his arm a small leaden tablet thickly engraved with a peculiar character, which I immediately perceived to be neither Arabic nor Persian.
