This bill must be dismissed. We do not sit here to enforce contracts of separation between husband and wife,in 285] the *shape of a decree for a divorce. The whole proceeding for divorce is strictly adversary; if it appear there is collusion between the parties, or an agreement, or that a divorce is prayed for, for a cause which has been forgiven by the parties, a divorce is never decreed. The proof of adultery cannot be received under this petition.
