Upon comparing these remarks of Mr. Upcott with Lowndes' _Bibliographer's
Manual_, p. 1645., col. 1., it will be seen that the latter was not
accurately informed as to Perry's copy; Professor Porson having had no
farther share in that laborious work than the recommending Mr. Upcott to
undertake the collation, from which Perry's copy was subsequently
corrected.
