The conclusion of the adventure of Bemoy, was extremely tragical.  A quarrel having arisen between him and the commander of the expedition, the latter stabbed the African prince on board his own vessel.  Whether this violent deed was prompted by the heat of passion, or by well-grounded suspicions of the prince’s fidelity, was never fully investigated, but the king learned the event with great regret, and in consequence, gave up his design of building a fort on the Senegal.  Embassies were, however, sent to the most powerful of the neighbouring states, nor was any pause made in the indefatigable efforts to trace the abode of Prester John.  Amongst the great personages, to whom an embassy was sent, are mentioned the kings of Tongubutue, (Timbuctoo,) and Tucurol, a Mandingo chief named Mandimansa, and a king of the Foulhas, with all of whom a friendly intercourse was established.  All endeavours were, however, vain as to the primary object, but the Portuguese thereby gained a more complete knowledge of this part of interior Africa than was afterwards attained in Europe till a very recent period.

There is, however, one circumstance attending these discoveries of the Portuguese, and the embassies, which they in consequence sent to the native princes, which deserves particular attention.  There is very little doubt existing, but that the Portuguese were acquainted with the town and territory of Timbuctoo; and the question then presents itself, by what means did the Portuguese succeed in penetrating to a kingdom, which, for centuries afterwards, baffled all the efforts of the most enterprising travellers to arrive within some hundred miles of it.  The city of Timbuctoo, for instance, was, for a considerable length of time, the point to which all the European travellers had directed their attention; but so vague and indefinite were the accounts of it, that the existence of Timbuctoo as a town, began to be questioned altogether, or at least, that the extraordinary accounts, which had been given of it, had little or no foundation in truth.  From the time of Park to the present period, we have information of only three Europeans reached Timbuctoo, and considerable doubt still exists in regard to the truth of the narrative of one of them.  It is true that the intelligence of the Portuguese embassies, as respecting the particulars of them, and the manner in which they were conducted, has either perished, or still remains locked up in the archives of the Lusitanian monarchy.  But when we look into the expeditions, which have been projected of late years into the interior of Africa, we cannot refrain from drawing the conclusion, that the character of the African people must have undergone a change considerably for the worse, or that our expeditions are not regulated on those principles so as to command success.
