[POMPONIUS libro trigensimo tertio ad Sabinum. ] §18.1.33.prCum in lege uenditionis ita sit scriptum: 'flumina stillicidia uti nunc sunt, ut ita sint', nec additur, quae flumina uel stillicidia, primum spectari oportet, quid acti sit: si non id appareat, tunc id accipitur quod uenditori nocet: ambigua enim oratio est.
[POMPONIUS libro trigensimo tertio ad Sabinum.] When it is written in the terms of a sale: 'that the flow of rain-water and the dripping of water shall remain as they now are', and it is not added which flow or dripping is meant, we must first look to what was agreed upon; if this does not appear, then that which is disadvantageous to the seller is accepted, for the phrasing is ambiguous.
