"It has always appeared to me, that some latent truth will ever be found in opinions, which are held by all nations. There are hidden chains of reasoning perfectly undefinable, which go on in the minds of all men, and convince them of particular facts, with a certainty beyond demonstration which no argument can overthrow, and no sophistry can materially shake. Of this nature is man's persuasion of his own existence, and of the existence of a material world. But there are also other convictions, which, though not so perfectly established, and equally incapable of proof, may be considered almost certainties by the general conclusion of all nations to that effect.
"I have just said, that in all the countries in which it has been my fate to reside, I have ever found a conviction prevail of the existence of a class of beings, (if I may use the expression), just beyond the limits of clay; in fact, our next link in the chain of existence. This belief was of course expressed under the form of a thousand superstitions, but still the foundation was the same; and as I always make it a point of sparing even prejudices, when I cannot remove them, instead of jesting at the tales which I have at different times heard upon the subject, I have always listened with attention, and given way to the feelings of those who recited them. So often has this occurred to me, and so great a wanderer have I been, that I have at present by me sufficient notes of the various vague forms which this belief takes in different countries, to compile an epitome of the superstitions of almost all nations.
"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.
