[IDEM libro trigensimo primo ad edictum. ] §17.2.44.prSi margarita tibi uendenda dedero, ut, si ea decem uendidisses, redderes mihi decem, si pluris, quod excedit tu haberes, mihi uidetur, si animo contrahendae societatis id actum sit, pro socio esse actionem, si minus, praescriptis uerbis.
[THE SAME, in his thirty-first book on the Edict.] If I have given you pearls to sell on the terms that, if you sell them for ten, you are to return ten to me, and if for more, you are to keep the excess, it is my opinion that, if this was done with the intention of forming a partnership, the action pro socio lies; if not, the action praescriptis uerbis lies.
