33 On the other hand, there is no doubt that even an absolute legacy to the master of a slave who is instituted heir is good: for, even supposing that the testator dies immediately after making the will, the right to the legacy does not necessarily belong to the person who is heir; for the inheritance and the legacy are separable, and a different person from the legatee may become heir through the slave; as happens if, before the slave accepts the inheritance at his master's bidding, he is conveyed to another person, or is manumitted and thus becomes heir himself; in both of which cases the legacy is valid. But if he remains in the same condition, and accepts at his master's bidding, the legacy is extinguished. 34 A legacy given before an heir was appointed was formerly void, because a will derives its operation from the appointment of an heir, and accordingly such appointment is deemed the beginning and foundation of the whole testament, and for the same reason a slave could not be enfranchised before an heir was appointed. Yet even the old lawyers themselves disapproved of sacrificing the real intentions of the testator by too strictly following the order of the writing: and we accordingly have deemed these rules unreasonable, and amended them by our constitution, which permits a legacy, and much more freedom, which is always more favoured, to be given before the appointment of an heir, or in the middle of the appointments, if there are several. 35 Again, a legacy to take effect after the death of the heir or legatee, as in the form: 'After my heir's death I give and bequeath,' was formerly void, as also was one to take effect on the day preceding the death of the heir or legatee. This too, however, we have corrected, by making such legacies as valid as they would be were they fiduciary bequests, lest in this point the latter should be found to have some superiority over the former.
