In a recent letter -Phys. Rev. Lett. 73, 3331 (1995)-, the conclusion was reached that, in the one-dimensional Calogero model, only the second virial coefficient is affected by the statistical parameter $\\alpha$, where $\\alpha$ is related to the coupling constant $\\kappa/ x_{ij}^2$ of the Calogero interaction by $\\kappa=\\alpha(\\alpha+1)$. We argue that it is not so, i.e. all virial coefficients are affected, if the thermodynamic limit is properly taken.
