How criminal then were they, who, knowing this, had neither publicly proposed, nor in their practice adopted, a remedy! The average loss of the slaves on board, which had been calculated by Mr.
Wilberforce at twelve and a half per cent., had been denied.

He believed this calculation, taking in all the circumstances connected with it, to be true; but that for years not less than one tenth had so perished, he would challenge those concerned in the traffic to disprove.

Much evidence had been produced on the subject; but the voyages had been generally selected.
There was only one, who had disclosed the whole account.

This was Mr.
Anderson of London, whose engagements in this trade had been very inconsiderable.

His loss had only amounted to three per cent.; but, unfortunately for the Slave-traders of Liverpool, his vessel had not taken above three fourths of that number in proportion to the tonnage which they had stated to be necessary to the very existence of their trade.
An honourable member (Mr.Grosvenor) had attributed the protraction of this business to those who had introduced it.
