And they resolved lastly, that the interval, in which the Slave-trade should be permitted to continue, afforded a prospect of redoubled cruelties and ravages on the coast of Africa; and that it imposed therefore an additional obligation on every friend to the cause to use all constitutional means to obtain its immediate abolition.
At a subsequent meeting they voted their thanks to the right honourable Lord Muncaster, for the able support he had given to the great object of their institution by his Historical Sketches of the Slave-trade, and of its Effects in Africa, addressed to the People of Great Britain; and they elected the Reverend Richard Gifford and the Reverend Thomas Gisborne honorary and corresponding members; the first on account of his excellent sermon before mentioned and other services, and the latter on account of his truly Christian and seasonable pamphlet, entitled Remarks on the late Decision of the House of Commons respecting the Abolition of the Slave-trade.
On the twenty-third of April, the House of Commons resolved itself into a committee of the whole House, to consider the subject again; and Mr.
Beaufoy was put into the chair.
Mr.Dundas, upon whom the task of introducing a bill for the gradual abolition of the Slave-trade now devolved, rose to offer the outlines of a plan for that purpose.

He intended, he said, immediately to abolish that part of the trade, by which we supplied foreigners with slaves.

The other part of it was to be continued seven years from the first of January next.
He grounded the necessity of its continuance till this time upon the documents of the Negro-population in the different islands.

In many of these, slaves were imported, but they were re-exported nearly in equal numbers.

Now all these he considered to be in a state to go on without future supplies from Africa.
