[IDEM libro sexto ad Sabinum. ] §45.1.16.prSi Stichum aut Pamphilum mihi debeas et alter ex eis meus factus sit ex aliqua causa, reliquum debetur mihi a te.
[THE SAME, in the sixth book on Sabinus.] If you owe me Stichus or Pamphilus and one of them has become mine from some cause, the remaining one is owed to me by you.
§45.1.16.1Stipulatio huiusmodi 'in annos singulos' una est et incerta et perpetua, non quemadmodum simile legatum morte legatarii finiretur.
A stipulation of this kind, "for each year," is single and uncertain and perpetual, unlike how a similar legacy would be terminated by the death of the legatee.
