I had long had the honour of the friendship of Mr. Bennet Langton, and I determined to carry him one of my books, and to interest his feelings in it, with a view of procuring his assistance in the cause. Mr. Langton was a gentleman of an ancient family and respectable fortune in Lincolnshire, but resided then in Queen Square, Westminster. He was known as the friend of Dr. Johnson, Jonas Hanway, Edmund Burke, Sir Joshua Reynolds, and others. Among his acquaintance, indeed, were most of the literary, and eminent professional, and public-spirited men of the times. At court, also, he was well known, and had the esteem of his majesty (George III.), with whom he frequently conversed. His friends were numerous also, in both houses of the legislature. As to himself, he was much noted for his learning, but most of all for the great example he gave, with respect to the usefulness and integrity of his life. By introducing my work to the sanction of a friend of such high character and extensive connexions, I thought I should be doing great things. And so the event proved. For when I went to him after he had read it, I found that it had made a deep impression upon his mind. As a friend to humanity, he lamented over the miseries of the oppressed Africans; and over the crimes of their tyrants, as a friend to morality and religion. He cautioned me, however, against being too sanguine in my expectations, as so many thousands were interested in continuing the trade. Justice, however, which he said weighed with him beyond all private or political interest, demanded a public inquiry, and he would assist me to the utmost of his power in my attempts towards it. From this time he became a zealous and active coadjutor in the cause, and continued so to the end of his valuable life.
