Those who spoke in favour of it were; Mr.
Pitt, Fox, William Smith, Whitbread, Francis, Burdon, Vaughan, Barham, and Serjeants Watson and Adair.
While the foreign Slave-bill was thus passing its stages in the Commons, Dr.Horsley, bishop of Rochester, who saw no end to the examinations, while the witnesses were to be examined at the bar of the House of Lords, moved, that they should be taken in future before a committee above-stairs.

Dr.
Porteus, bishop of London, and the Lords Guildford, Stanhope, and Grenville, supported this motion.

But the Lord Chancellor Thurlow, aided by the Duke of Clarence, and by the Lords Mansfield, Hay, Abingdon, and others, negatived it by a majority of twenty-eight.
At length the bill itself was ushered into the House of Lords.

On reading it a second time, it was opposed by the Duke of Clarence, Lord Abingdon, and others.

Lord Grenville and the Bishop of Rochester declined supporting it.
