Lictenstein states that "among the Koossas, (a nation of South Africa,) there are certain prevailing notions respecting moral [ceremonial] uncleanness. All children are unclean till they are admitted among grown-up persons (which happens with the males through the various ceremonies attending circumcision); all lying-in women are unclean for the first month; all men who have lost their wives, for a fortnight, and all widows for a month; a mother who has lost a child, for two days; all persons who have been present at a death, the men returning from a battle, etc. No one may have intercourse with such an unclean person, till he has washed himself, rubbed his body with fresh paint, and rinsed his mouth with milk. But he must not do this till after the lapse of a certain time, fixed by general consent for each particular case, and during this time he must wholly refrain from washing, painting, or drinking milk."
