Recently Horowitz et al. (ibid., vol.28, p.829, 1983) have proposed a modification of Burlin's general cavity theory for photons based on their proof (Horowitz and Dubi 1982) that, in general, the average path length for radiation crossing the cavity is not equal to the average path length for radiation created within the cavity. Two letters to the Editor have recently been published (Janssens ibid., vol.28, p.745, 1983, Kearsley ibid., vol.29, no.1, p.57-9, 1984) commenting on the validity and usefulness of the Burlin-Horowitz general cavity expression. Horowitz and Moscovitch discusses a number of the results obtained from using the Burlin and Burlin-Horowitz expressions.
