  We showed that the equations (3), (4), (5) and (6), used in the paper Total
and fractional densities of states from caloric relations by S. F. Chekmarev
and S. V. Krivov, Phys. Rev. E 57 2445 (1998), are incorrect, the data,
presented in the paper by lines on Figs. 1, (3a) and (3b), are not correct, the
data presented by the symbols on Figs. 3(a) and 3(b) in the paper are made
manually (false), all conclusions made in the paper have no sense, the
assertion in the paper that the molecular dynamics simulations sample the
potential energy surface not uniformly, but according to the fractional
densities of state for the isomers is incorrect. We showed also that the total
and fractional densities of states obtained in the paper from caloric relations
are not equal to that of microcanonical ensemble of clusters, the ensemble of
clusters used in the paper does not represent the microcanonical ensemble of
clusters.
