Arrowsmith by Sinclair Lewis

Martin was enthusiastic during Better Babies Week. Leora and he weighed babies, examined them, made out diet charts, and in each child saw the baby they could never have. But when it came to More Babies Week, then he was argumentative. He believed, he said, in birth-control. Pickerbaugh answered with theology, violence, and the example of his own eight beauties.

Martin was equally unconvinced by Anti-Tuberculosis Week. He liked his windows open at night and he disliked men who spat tobacco juice on sidewalks, but he was jarred by hearing these certainly esthetic and possibly hygienic reforms proposed with holy frenzy and bogus statistics.
