“As soon as from abatement of the pestilence, I could safely go abroad, I met and renewed my acquaintance with several of the caravan, who remained in the city, expecting the return of others from Mecca. A French commercial house, on whom I had no letters of credit or other claim to confidence, than what arose from private friendship and esteem, having handsomely offered such advance of monies as I might require, I was enabled to prepare for my journey, and set out with this caravan, as soon as complete and ready for departure. All these designs were suddenly frustrated by the arrival of the French on the coast of Egypt. Those who formed the caravan at Cairo quickly dispersed; that from Mecca coming to join it was not yet arrived: myself and other Europeans were seized and confined in the castle, rather as a place of refuge from the indignation and fanaticism of the populace, than as a prison, and we remained there until the arrival of the French at Cairo. “Soon after their coming, I made acquaintance with two of their learned men, Berthollet and Monge, they liberated and presented me to the Commander in Chief, and he received me with every mark of attention and goodness. His regard for science, and esteem of learned men are too well known to render it necessary for me to expatiate on these high qualities. He promised me protection, he offered me money or whatever was requisite to my undertaking, and he directed the necessary passports to be prepared for me. “I lost no time in seeking out my friends, the merchants of Fezzan, and renewing my connections with them. Gradually as the public tranquillity became assured, they returned, one by one into the city, till the whole were again assembled; and fifteen days have now passed, since we have been making preparations for our final departure, actually fixed for the day after to-morrow. “Commonly those who engage in an extraordinary enterprise, consider means yet more extraordinary, as requisite to the success of the undertaking: my opinion, and therewith procedure will be founded on directly the contrary proposition. The plan which I have chalked out for my journey will be simple and easy to pursue. You shall have it in a single line, “it is to travel as a Mahommedan merchant of the caravan.” I am assured that under such character, I can travel with the same surety as the natives of the country. “Many of the caravan having been at Mecca, are aware that there are numbers of good Mussulmen from various countries who speak not Arabic, and who have different usages and customs; and thus simply attaining a knowledge of certain religious ceremonies and prayers, there is no difficulty in passing generally as a Mahommedan; for as to a certain less equivocal criterion of a personal nature, the delicacy of Mahommedan manners precludes any danger of inquiry.
