When will the laws of heredity, and the by-laws of agnation result in an altruism, where human bloodshed is an unknown horror?
"At the Mercy of Tiberius"
August Evans Wilson
Thus, brothers by the same father are agnates, whether by the same mother or not, and are called 'consanguinei'; an uncle is agnate to his brother's son, and vice versa; and the children of brothers by the same father, who are called 'consobrini, are one another's agnates, so that it is easy to arrive at various degrees of agnation.
"The Institutes of Justinian"
Caesar Flavius Justinian
2 The relation of agnation can also be established by adoption, for instance, between a man's own sons and those whom he has adopted, all of whom are properly called consanguinei in relation to one another.
