We had scarcely been a day at Mesurata before the report of our having a tibeeb (or doctor) in our party soon brought us a multitude of visiters; and the demand for medicine became so extensive, that the contents of twenty medicine-chests, such as that which we had with us, would not have satisfied one-half of the applicants. By far the greater number of those who presented themselves had nothing whatever the matter with them; but there were still many cases of real distress which required and obtained assistance. The most prevalent diseases were those of the eye, and there were many very alarming cases of dysentery; but Mr. Campbell’s attention and medical skill soon began to produce very favourable symptoms, and as much of the medicine as could possibly be spared was administered to and distributed amongst those who required it. As is usual, however, in barbarous countries, there were many simple beings whom it was impossible to convince that the powers of medicine are limited, and they were so fully persuaded of Mr. Campbell’s omnipotence, that he soon found it useless to deny it. To meet this emergency he found it better to make up some little harmless ingredients for their use, and to tell them that the rest was in the hands of the prophet, who had alone (under Allah) the power to cure them completely. With this declaration, and the medicine together, without which they would by no means have been satisfied, the petitioners used to retire well pleased with their physician, and convinced that the draught or the powders which they had received would infallibly remove their infirmity, however incurable it might be. A young woman, in the mean time, who resided near the tents, was attacked, after eating a quantity of bazeen[10], with a violent headache and pain in the stomach; and a celebrated Marábūt, who had lately arrived at Mesurata, was called in to administer his assistance. The holy man did not refuse to comply with the summons; and when he made his appearance at the door of her tent, Mr. Campbell, and such of our party who were near, were led by curiosity to the same place; and taking up, unperceived, an advantageous position, were able to understand, with the assistance of the interpreter, the whole of the conversation which ensued.
