and those of the deceased shall be erased. The limit of the marriage-age shall be from sixteen to twenty years—the longest time allowed—for a girl, and for a boy from thirty to thirty-five. The limit for official posts shall be forty for a woman and thirty for a man. For military services the limit shall be from twenty years up to sixty for a man; for women they shall ordain what is possible and fitting in each case, after they have finished bearing children, and up to the age of fifty, in whatever kind of military work it may be thought right to employ their services.
