So fixed was his intention of executing some one of these plans, that near three years of suffering were unable to abate his resolution; and the pain he endured at being ultimately compelled to relinquish them, had induced him to neglect the only opportunity that was likely to offer of personal deliverance, till the destitution of the means of living roused him from his lethargy; and the ridicule of his Mohammedan friends, who, fatalists as they are, yield to circumstances, instructed him that to despair was weakness and not fortitude; and that the frail offspring of hope, nursed by credulity, and not by prudence, marks the morbid temperament of the mind that conceived it. The following papers would perhaps have been something less imperfect, if what was originally committed to writing had been altogether within the reach of the writer, when he began to prepare them for publication. Two accidents, however, both equally unforeseen, rendered abortive his hope of compensating in some measure for the general failure in his design, by greater exactness and detail as to the particulars of what he had actually seen. The losses he had sustained in Soudân, were not very important, comprising only some specimens of minerals, vegetables, and other cumbrous materials, which he designed to have brought with him. On his arrival in Kahira, he thought it would be an impediment, in his journey through Syria, to transport all he possessed thither, and therefore caused the greater part of his baggage to be sent to Alexandria; among which were copies of such papers as he thought least unfit for the use of a third person. In the number he regrets a register of the caravans which had arrived in Kahira from Fûr since the year of Hejira 1150, containing an account of their numbers, and many other curious particulars; copied from a book belonging to the shech of the slave-market in Kahira. A kind of general itinerary, in the hand-writing of a Jelab of his acquaintance, containing the roads of Eastern Africa. A vocabulary of the Fûrian language, compiled by himself. Some remarks on natural history. List of names of places both in Egypt and Fûr, written by an Arab. The detail of particulars relating to the time and manner of his observations in Astronomy, with other remarks tending to illustrate the geography of his route. To return to a few considerations on the present intercourse between Egypt and Abyssinia.
