An essay on the operation in wills of the word issue : and also of the words heirs of the body, dying without issue, and dying without leaving issue, and the periphrases of them : with a familiar illustration of that ancient rule of law, commonly called the rule in Shelley's case, and a short historical deduction of the rule from its feodal origin : with three introductory chapters on the nature of estates at common law, remainders, conditions, conditional limitations, and executory devises / by James Hawkshead.
