Absolutely pristine example of Wilberforce's dying accomplishment. The Bill was read three days before his death and was voted upon shortly after he breathed his last. It was the nail in the coffin of slavery; the 1807 Act was a huge start, but it didn't prevent British plantation owners from concentrating their wealth in the colonies where they could still freely use slave labor, etc., 

No examples on the market we are able to trace, nor one at auction. 

A Bill Intituled an Act for the Abolition of Slavery throughout the British Colonies, for Promoting the Industry of Manumitting Slaves and for Compensating the Persons Hitherto Entitled to the Services of such Slaves. 1833. 

Pristine, crisp condition.
