Vuorinen proved in 1988 that Mori's constant M (n, K) for K-quasiconformal maps of the unit ball in R n onto itself keeping the origin fixed satisfies M (n, K) → 1 when K → 1. We give here an alternative proof of this fact, with a quantitative upper bound for the constant in terms of elementary functions. Our proof is based on a refinement of a method due to G.D. Anderson and M. K. Vamanamurthy. We also give an explicit version of the Schwarz lemma for quasiconformal self-maps of the unit disk. Some experimental results are provided to compare the various bounds for the Mori constant when n = 2 .
