The Mormons have introduced it into their religion. The negro king of Loango shows us what degree polygamy may reach among princes and chiefs, for he possesses seven thousand wives, while the chiefs of the Fiji Islands are content with twenty to one hundred. Among savage races we find monogamy in the natives of the Andaman islands, among the Touaregs, the Weddas, the Iroquois, the Wyandottes, and even in some Australian tribes. With others, polygamy is only permitted to the chiefs. But most of the population are monogamous even among polygamous races, and there are very few peoples in which all the men possess several wives. In India, 95 per cent. of the Islamites are monogamous, and in Persia even 98 per cent. Polygamy is nearly everywhere a privilege of princes, chiefs, and rich men. The two following facts also show a tendency to monogamy among polygamous races: (1). One of the wives, generally the first, has prerogatives over the others. (2). In reality, the polygamous man nearly always gives sexual preference to one only, or to a few of his wives. There are, however, some polygamous races in which the husband has sexual intercourse with each of his wives according to a regular programme, taking each of them in turn for several days, weeks or months. With others, on the contrary, a number of married women remain in reality virgins, because the husband does not desire them, and they are nothing more than domestics. Among these people the husband as a rule only takes a second wife when the first has grown old, so that bigamy becomes the ordinary form of marriage. The Cingalese were polyandrous before the English conquest, and so many as seven men had one wife in common. Polyandry is especially the custom in Thibet. Among polyandrous peoples the husbands are not all on the same footing of equality, some hold an inferior position, corresponding nearly to that of concubines, another sign of the tendency to monogamy. Among the Togas marriage in groups is constituted as follows: All the brothers are husbands of the wife of the elder brother, and all the sisters of this wife are at the same time wives of their brothers-in-law. If we except prostitution, this is the only case in man which approaches promiscuity. Marriage in groups, however, is extremely restricted promiscuity.
