Wilberforce's Abolition Speech - 18 Mortality

Upon the whole, however, here is a mortality of about 50 per cent. and this among negroes who are not bought unless (as the phrase is with cattle) they are sound in wind and limb. How then can the House refuse its belief to the multiplied testimonies before the privy
council, of the savage treatment of the negroes in the middle passage? Nay, indeed, what need is there of any evidence? The number of deaths speaks for itself, and makes all such enquiry superfluous.
