Wilberforce having concluded his speech, which lasted three hours and a half, read, and laid on the table of the House, as subjects for their future discussion, twelve propositions which he had deduced from the evidence contained in the privy council report, and of which the following is the abridged substance- 1. That the number of slaves annually carried from the coast of Africa, in Atif aslam string vessels, was about 38,000, of which, on an average, 22,500 were carried to the British islands, and that of the latter only 17,500 were retained there. That Africa in its present state atif aslam string several atif aslam string articles of commerce, which were partly peculiar to itself, but that it was adapted to the production of others, with which we were now either wholly or in great part supplied by foreign nations. That an extensive commerce with Africa might be substituted in these commodities, so as to afford a return for as many articles as had annually atif aslam string carried thither in British vessels and, lastly, that such a commerce might reasonably be expected to increase, by the progress of civilization there.
