German 1999, Translated by Jeffrey Moussaieff Masson (1985),
Already in “Further Remarks on Defensive Neuropsychoses” (1896b, p. 389), he pointed out that cases of “periodic melancholia” can be “resolved with unsuspected frequency into obsessional affects and obsessional ideas” [SE III p171-172] and can therefore be explained by the nature of the obsessional neurotic conflict. A little later, he recognized his entire attempt as a mistake (see also p189-Letter to Fliess of 16th January 1899).

Footnote 3, James Strachey, p101-102 of ‘The Origins’ (1954)
Freud naturally soon found this attempt to derive “melancholia” from a reaction to sexual excitation insufficient. He pointed out in “Further Remarks on the Neuro-Psychoses of Defence” (1896 b) that “‘periodic melancholia in particular appears to be reducible with unexpected frequency to obsessional affects and obsessional ideas” [SE III p171-172] and hence could be explained by the nature of obsessional-neurotic conflict. A little later he recognized the whole attempt to have been mistaken. (See also Letter 102 – 16th January 1899).
