We shall there endeavour to establish the following propositions:-1. That the most ancient system in which the idea of blood-relationship was embodied, was the system of kinship through females only. 2. That the primitive groups were, or were assumed to be, homogenous. 3. That the system of kinship through females only tended to render the exogamous groups heterogeneous, and thus to supersede the system of capturing wives. 4. That in the advance from savagery the system of kinship through females only was succeeded by a system which acknowledged kinship through males also; and which, in most cases passed into a system which acknowledged kinship through males only. 5. That the system of kinship through males tended to rear up homogeneous groups, and thus to restore the original condition of affairs- wher the exogamous prejudice survived- as regards both the practice of capturing wives and the evolution of the form of capture. 6. That a local tribe, under the combined influence of exogamy and the system of female kinship, might attain a balance of persons of different sexes regarded as being of different descent, and that thus its members might be able to intermarry with the principle of exogamy. 7. That a local tribe, having reached this stage and grown proud through success in war, might decline intermarriage with other local tribes and become a caste.

我们将明确一下命题：1、大部分包括血统联系观念的古代体系是只通过女系计算血族关系的体系。2、原始群是或被假定是纯系的。3、只按女系计算血族关系的系统倾向于实行异类群的外婚制，并因而取代盗妻的体系。4、从只按女系计算血族关系的野蛮系统发展来的高级系统为也承认通过父系计算血族关系的系统所继承。5、通过父系计算血族关系的系统往往跃回均质的群体，并且因此恢复到事情的原始状态——外婚的偏执得以幸存——被认为既是实行盗妻的又是从盗妻发展的。6、一个本地部落在外婚制和女系血族关系的联合影响下，可能达到被认为不同世系的不同性别人们的平衡，而且因此成员可能得以按外婚原则通婚。7、到达这一阶段而且通过胜利的战争获得自豪的本地部落，可能拒绝与本地部落的联姻而变成世袭种姓。
