Coffin, a very intelligent, pleasing, active lad, but of course illiterate, remained in Abyssinia until the year 1827, when he surprised his brother, who is now valet to Lord ----, and who had long supposed him to be dead, by suddenly calling upon him in London. From a conversation which we have just had with Coffin, we understand that he is about to return to Abyssinia; the present government having refused to give him anything for the king of that country beyond a trifling complimentary present. As, excepting Lord Valentia, Salt, Pierce, and Coffin, no European travellers have visited Abyssinia since the days of Bruce, we have conceived it to be absolutely necessary, in order that the reader may be enabled to form a correct judgment, to explain the connexion which exists between Lord Valentia, his secretary, his valet, and Nathaniel Pierce the English sailor, who, after deserting from his majesty's brig the Antelope, was patronised by Lord Valentia: for, as the two former, men of education and distinction, have already most violently attacked Bruce, and as the two latter are, we believe, about to follow (naturally enough) the opinions of their masters (we even understand that Pierce's life has been actually prepared for publication by one or more of Mr. Salt's friends), we feel it to be a duty which we owe to science, to truth, and to Bruce's memory, to show that these four individuals, without any improper intention, support rather than corroborate each other; and, having made this explanation, we no less unwillingly proceed to notice a few of the observations which have been made against Bruce by Lord Valentia and Mr. Salt.
