Mr.Powys read the account .-- He became, in consequence of it, convinced, as, indeed, he could not otherwise be, of the truth of what I had asserted, and he declared at the same time that, if this were true, there was nothing so horrible related of this trade, which might not immediately be believed.

Mr.Powys had been always friendly to this question, but now he took a part in the distribution of my books.
Among those, whom I visited, was Mr.Wilberforce.On my first interview with him, he stated frankly, that the subject had often employed his thoughts, and that it was near his heart.

He seemed earnest about it, and also very desirous of taking the trouble of inquiring further into it.
Having read my book, which I had delivered to him in person, he sent for me.

He expressed a wish that I would make him acquainted with some of my authorities for the assertions in it, which I did afterwards to his satisfaction.

He asked me if I could support it by any other evidence.
