This cause is before us upon the appeals of the defendant from an interlocutory decree and a final decree entered by the Superior Court. Motion has been filed by the plaintiff after the periods for filing appeal had expired asking that leave be granted to claim and enter her appeal. This motion must be denied.

The defendant says in her brief that the amount found due was agreed to be correct if the ruling of the court was proper. It is not open for her, therefore, now to contest it. The order must be
