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.
