  The notion of intrinsic algebraic entropy of an endomorphism of a given
Abelian group has been recently introduced in [D. Dikranjan, A. Giordano Bruno,
L. Salce, S. Virili, Intrinsic algebraic entropy, J. Pure Appl. Algebra 219
(2015) 2933-2961]. In this short note we provide a correct argument to prove
one of the basic properties of the intrinsic algebraic entropy: the Logarithmic
Law. In fact, this property was correctly stated in [op. cit.] but, as we will
show with an explicit counterexample, the original proof contains a flaw.
