Attribution to James T. Fields incorrectly made in Oppenlander's Contributor Index and the 'Pilgrim' edition of Dickens's Letters. The correct attribution is discussed in Sharon M. Harris, Rebecca Harding Davis and American Realism (Pennsylvania: University of Pennsylvania Press, 1991), pp. 96-99, and numerous other print sources. DJO is grateful to Christine Kyprianides Potter for alerting us to the need for this correction.
