title: A reply to W. H. James.
abstract: Abstract   The objection of W. H. James to my computation on p. 330, for the sample of Créteil, is valid. For reasons that are developed elsewhere in my paper, the current pregnancy of any woman was omitted in the elaboration of Table 6. Therefore, in order to derive continuation rates, we must re-include this pregnancy in each individual pregnancy history. Since women whose previous pregnancies ended in induced abortions had been excluded, we must do the same for women whose current pregnancy was interrupted by an induced abortion.
