In my Dover edition the Additions in Vol III (p502) have a note saying "N, O should be O, P, II 500: see I, 504" ie the two he added in Additions and Corrections Vol 2 should be renamed as O and P, not N and O.

A-M were given in the main text of Vol I and N was given in the Additions and Corrections to Vol I. The two in Vol II had been incorrectly named as N,O and the note in Vol III corrects that.
