Among a great many peoples, even those comparatively little advanced in general culture, the husband is permitted to divorce his wife only for definite reasons.[760] The causes of legal divorce most constantly recurring are adultery and sterility. In a great many cases divorce is absolutely forbidden after a child, usually a son, is born. It should be carefully noted that many of the alleged examples of divorce on the ground of sterility are, strictly speaking, not divorces at all; but rather illustrations of the so-called "proof-marriages" so often met with in all parts of the world. Not until the term of probation is "blessed" by the arrival of offspring is the "marriage" in such cases regarded as complete, though this may not always be the implied condition. With the proof-marriages are sometimes described as identical in character the "time-marriages" found among many peoples; but this form of union is, properly speaking, usually a real marriage not dependent for its consummation upon the birth of a child, being stipulated in advance for a certain term.[761] Besides the two leading grounds of divorce already mentioned, many others, some of them trivial, are prescribed by the laws of various peoples. Such are mistreatment, deformity, laziness, desertion, and incompatibility of temper. Sometimes the consent of the chief or other public authority is requisite. So, among the Hottentots, a man may divorce his wife only "upon shewing such cause as shall be satisfactory to the men of the kraal where they live;"[762] and among the aborigines of Victoria, as already seen, a childless wife may be dismissed for serious misconduct only when the sanction of the tribal chief is obtained.[763] By Chinese law divorce _must_ be granted in case of any of the numerous impediments[764] to marriage; or when the wife is guilty of adultery. For that offense the aggrieved husband may kill the offending wife and her paramour, if he catch them _in flagrante delicto_. But should the woman not be slain, she is punished, and the husband may drive her away or even sell her as a concubine, provided he has not pandered to the crime or does not sell her to the guilty man.[765] Furthermore, a marriage may be dissolved by mutual agreement;[766] and the husband is entitled to a divorce when the wife strikes him, is addicted to drunkenness or opium smoking, has been defiled before marriage, or when she leaves his house against his will.[767] Besides all these grounds, established by statute or recent usage, Confucius allows the husband a divorce for any of seven faults of the wife: barrenness, wantonness, inattention to parents-in-law, talkativeness, theft, jealousy, and inveterate disease such as leprosy.[768] But these grounds will not always warrant a separation. "They may be outweighed by particular merits of the woman or by special circumstances. If the wife has mourned three years for the husband's parents; if the family has grown rich during the marriage; or if
