The difference between the ordinary method of renormalization'< ·of Dyson and that of the present authors deVilloped in the previous paper is emphasized. In order to darify this difference, the renormalization ·of the two-electron Green-function is investigated. The. ~roof of the finiteness of the renormalized Green~fUnction seems to be given in quite a brief way. It is the e'ilsential point in this proof that there i~ no ambiguity in the order of integration appea~ing in course of calculationof Green· functions.
