It is clear, from this letter, that Bello understood what was proposed and accepted, but, with regard to the geographical position of his two sea-ports, he was evidently most grossly ignorant; for, admitting the ambiguity of the Arabic word _bahr_, which signifies any great collection of water, whether sea, lake, or river, merchant ships could not get up to Raka, which is an inland town, not situated on any coast or river. Be this as it may, an expedition, as already stated, was planned without loss of time, at the head of which Clapperton was placed. He was allowed to take with him, as a companion, a fellow-countryman of the name of Dickson, who had been brought up as a surgeon, in which capacity he had served in the West Indies, but had recently been studying the law. This person considered himself to be inured to a tropical climate, and was supposed to have a sufficient knowledge of medicine to take care of himself and the rest of the party. In an enterprise of this novel and hazardous nature, it was deemed advisable to unite two other gentlemen to those above-mentioned; in order that, when once at Soccatoo, two of them might be spared to set out from thence, and explore the country of Soudan in various directions. For this purpose, Captain Pearce of the navy, and Dr. Morrison, a naval surgeon, were selected; the former an active and accomplished officer, and a most excellent draughtsman; the latter well versed in various branches of natural history. Unhappily, it was not their good fortune to live long enough to put their respective talents in practice for the benefit of the public, or the gratification of their friends; having each of them, on the same day, fallen a sacrifice to the pestilential climate, at a very early period of their journey in Africa.
