Whenever by any form of words in any will or inter vivos conveyance, a remainder is limited, mediately or immediately, to the heirs or heirs of the body of a person to whom a life estate in the same subject matter is given, the persons who on the termination of the life estate are then the heirs or heirs of the body of the tenant for life, take as purchasers by virtue of the contingent remainder limited to them.
