Tristram Pugin has asked us to point out that Part I of his article ‘Through the Spectrum: The New Intimacy in French Music’ contained three avoidable errors. The composer Alain Bancquart's name is consistently misspelled as Banquart. Villiers de l'Isle-Adam's novel l'Eve future is mis-titled La nouvelle Eve. Pierre Bayle is not a composer of electro-acoustic music but an 18th-century philosopher: the composer is François Bayle. Although Tristram Pugin accepts ultimate responsibility for these errors, we consider he had had some right to expect they would be detected in editing; as they were not, the responsibility is also ours.
