An estate pur autre vie may be granted, not only to a man and his heirs, but to a man and the heirs of hisbody, which is termed a “quasi entail;” the interest so granted not being properly anestate-tail, (for the statute De Donis applies only where the subject of the entail is anestate of inheritance.) but yet so far in the nature of an estate- tail that it will go to theheir of the bod.v as special occupant during the life of the cestui que vie, in the samemanner as an estate of inheritance would descend, if limited to the grantee and theheirs of his body.
