Sumario:The aim of this paper is to present an alternative derivation within Frege's Arithmetic of theorem 149 in Grundgesetze der Arithmetik, which plays a central role in the proof of the theorem that states that every natural number has a successor. In Grundgesetze, the derivation of this theorem depends on the theorem IVa, whose analogue in Frege's Arithmetic (IVa*) is independent of the axioms of the system. It is shown that the use of IVa in Grundgesetze is not essential and therefore that (IVa*) is not necessary for derivation of theorem 149 within Frege's Arithmetic.
