The commitee held its fourth meeting on the twelfth of June. Among the subjects, which were then brought forward, was that of the journey before mentioned. The propriety and indeed even the necessity of it was so apparent, that I was requested by all present to undertake it, and a minute for that purpose was entered upon our records. Of this journey, as gradually unfolding light on the subject, and as peculiarly connected with the promotion of our object, I shall now give an account; after which I shall return to the proceedings of the commitee. CHAPTER XIV. _Author arrives at Bristol--Introduction to Quaker families there--Objects of his inquiry--Ill usage of seamen on board the ship Brothers--Obtains a knowledge of several articles of African produce--Dr. Camplia--Dean Tucker--Mr. Henry Sulgar--Procures an authenticated account of the treacherous massacre at Calebar--Ill usage of the seaman of the ship Alfred--Painful feelings of the author on this occasion._ Having made preparations for my journey, I took my leave of the different individuals of the commitee. I called upon Mr. Wilberforce, also, with the same design. He was then very ill, and in bed. Sir Richard Hill and others were sitting by his bed-side. After conversing as much as he well could in his weak state, he held out his hand to me, and wished me success. When I left him, I felt much dejected. It appeared to me as if it would be in this case, as it is often in that of other earthly things, that we scarcely possess what we repute a treasure, when it is taken from us.
