Dr Lyons’s admirable study of the downfall of Parnell, recently published, has raised once again the question of the relations between Joseph Chamberlain and the Irish leader and more particularly of the part alleged to have been played by Chamberlain in bringing about the latter’s ruin. Like the late Henry Harrison, who devoted so many eloquent pages to this subject, Dr Lyons had to write without access to Chamberlain’s own papers, which, however, do not contain, so far as I am aware, anything that is at variance with his main conclusions. Nevertheless, they do containcertain letters, which are not mentioned in J.L. Garvin’s Life of Joseph Chamberlain and which supplement Dr Lyons’s account.
