Nollaig Drake, the reviewer of The Inner World and Joan Riviere, in the last issue of Psychoanalytic Psychotherapy (Volume 7 No. 3, p. 283), has asked us to point out that a slip was made in a reference to the ‘third seminal paper’ in that volume, the title of which should have been quoted as ‘Analysis of the Negative Therapeutic Reaction’ , and not ‘A Contribution to the Psychogenesis of Manic Depressive States’ .
