The Marquis of Lansdownpresented a Petition from the Magistrates and Town Council, and principal Merchants of the City of Glasgow, praying that precautionary measures might be adopted before the Legislature should determine to abolish Slavery in the Colonies. The noble Marquis said, that although the petition which he had the honour to present, was of a different prayer to most of those which had been laid before their Lordships, yet it would be unjust to term it a petition in favour of slavery. The petitioners stated that the inhabitants of Glasgow had, from their intercourse with the West-Indies, opportunities which few others possessed, of knowing the true condition of slaves in the colonies, and although they by no means advocated the perpetuation of negro slavery, they were convinced that great mischief would be occasioned by a rash and sudden abolition.—To lie on the Table.
