DIVORCE.--The following are legal causes for an absolute divorce: Adultery; extreme cruelty; wilful desertion; wilful neglect; habitual intemperance; and conviction by either party of a felony. All decrees of divorce are first granted _nisi_, and an absolute or final decree cannot be secured until one year after the entry of the decree _nisi_. Marriages may be annulled on the following grounds: That the party petitioning for annulment was under age at the date of marriage; that the former husband or wife of either party was living and the former marriage undissolved at the time of the marriage in question; that one of the parties was of unsound mind when the marriage was concluded; that the marriage was procured by fraud; that the marriage was procured by coercion; that at the time of the marriage one of the parties was impotent, and such physical incapacity continues to the date of bringing the suit for annulment.
