"Translated into seven European languages. By founder of the Mothers' Clinic. 'Wise Parenthood' is a more popular treatise than 'Contraception.' The latter is intended to be a physician's manual. Favours the rubber cervical cup rather than the vaginal diaphram (Mensinga pessary). This is not in accord with the weight of authority" - Norman E. Himes, "A Guide to Birth Control Literature"
