That in any case where any land in the State of Texas was titled prior to the adoption of the Common Law on March 20, 1840, and there has been a judicial finding that the original grantee of said land abandoned said land prior to the adoption of the Common Law, and the State of Texas has at any time instituted suit for the recovery of said land, resulting in a final judgment adverse to the State of Texas whether on demurrer, exception, or a jury finding of fact, it shall be conclusively presumed that those now claiming said land under conveyance from, or judgment against, the original grantee or his heirs, are vested with all title to said land which was vested in said original grantee by virtue of any patent or title from the sovereignty of the soil to him.
