Another and more remote consequence of the cross-cousin marriage, if this become an established institution, is that the relationships of mother's brother and father's sister's husband will come to be combined in one and the same person, and that there will be a similar combination of the relationships of father's sister and mother's brother's wife. If the cross-cousin marriage be the habitual custom, B and b in Diagram 1 will be brother and sister; in consequence A will be at once the mother's brother and the father's sister's husband of C, while b will be both his father's sister and his mother's brother's wife. Since, however, the mother's brother is also the father-in-law, and the father's sister the mother-in-law, three different relationships will be combined in each case. Through the cross-cousin marriage the relationships
