(Peano, Arithm. princ., Praefatio, p. V)
This is (might be) the same text in Latino sine flexione:
Ad me es magis utile etiam scripto recente: R. DEDEKIND, Was sind und was sollen die Zahlen, Braunschweig, 1888, que contine acuto examinatione de questiones que pertine ad fundamento de numeros.
Comments unwelcome :)
The "Arithmetices principia nova methodo exposita" (written in Latin, Jove knows why) were published by Peano in 1899; he first used Lsf in "De latino sine flexione" and "Principio de permanentia", 1903. These two articles appeared in his Rivista di matematica and were re-issued together as a booklet.
This, of course, has nothing to do with the question of Peano's axioms (9 axioms in the Arithm. princ., 4 of which concerning the = sign) depending on previous works --not necessarily (only) Dedekind's. FWIW, Kennedy states Peano read Dedekind's article only when his own work was "going to press".
