Twelve negresses from Nubia brought a price

Which the West Indian market scarce could bring—

Though Wilberforce, at last, has made it twice

What 't was ere Abolition; and the thing

Need not seem very wonderful, for Vice

Is always much more splendid than a King:

The Virtues, even the most exalted, Charity,

Are saving—Vice spares nothing for a rarity.
