Abstract It is shown that a condition derived by Naqvi from the density matrix equation, and used by him to generalize the statistical theory, can be regarded as constituting a differential form of the virial theorem. This suggests that Naqvi's condition is satisfied by the customary treatments, and this is demonstrated directly.
