[IDEM libro quarto ad Uitellium. ] §28.5.59.prNemo dubitat recte ita heredem nuncupari posse 'hic mihi heres esto', cum sit coram, qui ostenditur.
[THE SAME, On Vitellius, Book IV.] No one doubts that an heir can be validly designated in this way: "Let this man be my heir," when the person who is pointed out is present.
§28.5.59.1Qui frater non est, si fraterna caritate diligitur, recte cum nomine suo sub appellatione fratris heres instituitur.
A person who is not a brother, if he is loved with brotherly affection, is validly instituted heir under the designation of "brother" along with his own name.
