A correction was made to a previous coordinate-free formulation of the displacement field of a triangular dislocation loop (Barnett, 1985). Then, taking account of this correction, it was shown that the formulation reduced to that given by Hirth and Lothe, which was restricted to a specially chosen coordinate system.
