¹ Dr. Maas makes the following observations on Vogliano's collation of the original papyri in London and Naples: ‘V. marks by round brackets (see p. x) those parts of the text which have either perished or become illegible since the Naples draughtsman copied them. He sometimes explains in his app. crit. why his readings differ from those transmitted by the ed. pr. or by Hayter. But he never gives drawings of his own like those in his earlier editions of Herculanean papyri, and leaves many doubtful readings unexplained. Even for the “edizione definitiva”, which, he says (p. 17) still remains to be made, he envisages no drawings, but a “riproduzione fototipica degli originali”; no specimen of such reproductions has so far been published.’
