  In a recent article, Werndl and Frigg discuss the relationship between the
Boltzmannian and Gibbsian framework of statistical mechanics, addressing in
particular the question when equilibrium values calculated in both frameworks
agree. In this paper, I address conceptual confusions that could arise from
their discussion, concerning in particular the authors' use of "Boltzmann
equilibrium". I also clarify the status of the Khinchin condition for the
equivalence of Boltzmannian and Gibbsian, and show that it follows under the
assumptions proposed by Werndl and Frigg from standard arguments in probability
theory.
