Lord Campbell (Lives of the Chief Justices, vol. ii. p. 418) says that Lord Mansfield first established the grand doctrine that the air of England is too pure to be breathed by a slave. The words attributed to Lord Mansfield, however, are not found in his judgment. They are in Hargraves argument, May 14, 1772, where he speaks of England as a soil whose air is deemed too pure for slaves to breathe in.Lofft: Reports, p. 2. [back]
