On page 153, the italic *e* should be removed from the denominator of Eqs. [35] and [36]. Thus, the denominators should be simply 1 + c r, where the subscript on r is 12 in Eq. [35] and ij in Eq. [36].

In concluding, the author also notes that quantum Monte Carlo (QMC) is the only quantum chemical method giving exact results for systems of a few electrons and the most accurate method for systems of thousands of electrons.
