Commissioned by Longman's Magazine and originally published as an article entitled «The Anatomy of Acting» (January, February and March 1888),  the essay seeks to investigate the theories expressed by Diderot in  the Paradoxe sur le comédien (see) (translated in English in 1883 (see)). The appendix contains a survey in English and French - Questions on the Art of Acting, Formulated on Behalf of the Editor of 'Longmans' Magazine,' by William Archer - the answers to which were supplied by the "leading actors and actresses of the day" and which form the basis of the text.
