[IDEM libro quinto ad Plautium. ] §19.4.2.prAristo ait, quoniam permutatio uicina esset emptioni, sanum quoque furtis noxisque solutum et non esse fugitiuum seruum praestandum, qui ex causa daretur.
[THE SAME in the fifth book on Plautius.] Aristo says that, since exchange is close to sale, it must be guaranteed that a slave given by virtue of the contract is healthy, free from thefts and damages, and not a runaway.
