Where, on the abatement of a suit, there is such a transmission of the interest of the incapacitated party that the title to it, as well as the person entitled, may be the subject of litigation in a court of chancery, the suit cannot be continued by a mere bill of revivor. but an original hill upon which the title may be litigated must be filed.
