[IDEM libro secundo definitionum. ] §41.2.49.prPossessio quoque per seruum, cuius usus fructus meus est, ex re mea uel ex operis serui adquiritur mihi, cum et naturaliter a fructuario teneatur et plurimum ex iure possessio mutuetur.
[THE SAME, in the second book of Definitions.] Possession through a slave of whom I have the usufruct is also acquired for me, either from my own property or from the labor of the slave, since he is held physically by the usufructuary and possession derives much from the law.
§41.2.49.1Qui in aliena potestate sunt, rem peculiarem tenere possunt, habere possidere non possunt, quia possessio non tantum corporis, sed et iuris est.
Those who are under another's power can hold a peculium, but they cannot have or possess it, because possession is a matter not only of physical fact but also of law.
§41.2.49.2Etsi possessio per procuratorem ignoranti quaeritur, usucapio uero scienti competit, tamen euictionis actio domino contra uenditorem inuito procuratore non datur, sed per actionem mandati ea cedere cogitur.
Although possession through an agent is acquired for one who is ignorant of it, whereas usucapion is competent only to one who is aware, nevertheless, the action on eviction is not granted to the owner against the seller against the will of the agent, but the agent is compelled by the action on mandate to cede it.
