He combated, from his own personal knowledge, the argument, that self-interest was always sufficient to insure good usage, and maintained that there was only one way of securing it, which was the entire abolition of the Slave Trade.

This letter of the Dean of Middleham, which was a little Essay of itself, was deemed of so much importance by the committee, but particularly as it was the result of local knowledge, that they not only passed a resolution of thanks to him for it, but desired his permission to print it.
The committee sat again on the 13th and 22nd of November.

At the second, the Dean of Middleham's answer was received.
