§ MR. BORTHWICKwished to explain some remarks he had made the other night. He had stated that 600 slaves had perished out of a cargo of 707, and that only 107 had reached their destination. 185 He had asserted that it was considered a safe and good speculation, if out of a cargo of 700 slaves 100 were safely landed; and the noble Lord in replying to him had said that "600 per cent" was not a proper expression, because 600 men could not die out of 100. He (Mr. Borthwick) maintained that the expression was a correct one, as expressing the comparative mortality which took place under the present system. Formerly the great complaint was, that ten per cent of the slaves shipped used to be lost before the vessel arrived at her destination; but it appeared that now only about 16 per cent were ever landed alive.
