Mr. 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 British 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.

2.  That these slaves, according to the evidence on the table, consisted, first, of prisoners of war; secondly, of free persons sold for debt, or on account of real or imputed crimes, particularly adultery and witchcraft; in which cases they were frequently sold with their whole families, and sometimes for the profit of those by whom they were condemned; thirdly, of domestic slaves sold for the profit of their masters, in some places at the will of the masters, and in others, on being condemned by them for real or imputed crimes; fourthly, of persons made slaves by various acts of oppression, violence, or fraud, committed either by the princes and chiefs of those countries on their subjects, or by private individuals on each other; or, lastly, by Europeans engaged in this traffic.

3.  That the trade so carried on, had necessarily a tendency to occasion frequent and cruel wars among the natives; to produce unjust convictions and punishments for pretended or aggravated crimes; to encourage acts of oppression, violence, and fraud, and to obstruct the natural course of civilization and improvement in those countries!

4.  That Africa in its present state furnished several valuable 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 been carried thither in British vessels:  and, lastly, that such a commerce might reasonably be expected to increase, by the progress of civilization there.

5.  That the Slave Trade was peculiarly destructive to the seamen employed in it; and that the mortality there had been much greater than in any British vessels employed upon the same coast in any other service or trade.

6.  That the mode of transporting the slaves from Africa to the West Indies necessarily exposed them to many and grievous sufferings, for which no regulations could provide an adequate remedy; and that in consequence thereof a large proportion had annually perished during the voyage.

7.  That a large proportion had also perished in the harbours in the West Indies, from the diseases contracted in the voyage, and the treatment of the same, previously to their being sold; and that this loss amounted to four and a half percent of the imported slaves.
