  In manuscript arXiv:1703.08719 [cond-mat.soft], it was claimed that the
well-known deduction of Tolman's law is not rigorous, since Tolman's argument
implies that two different definitions of the surface tension, called $\gamma$
and $\bar\gamma$ in the manuscript, coincide. This claim is retracted as it can
be shown by free-energy minimization that $\gamma = \bar\gamma$ indeed holds
for the Laplace radius. Joachim Gro\ss, Philipp Rehner, Carlos Vega, \O{}ivind
Wilhelmsen, and the anonymous reviewers of The Journal of Chemical Physics
contributed to finding the mistake in the manuscript.
