[IDEM libro sexto decimo ad Plautium. ] §44.7.48.prIn quibuscumque negotiis sermone opus non est sufficiente consensu, iis etiam surdus interuenire potest, quia potest intellegere et consentire, ueluti in locationibus conductionibus, emptionibus et ceteris.
[THE SAME, from his sixteenth book on Plautius.] In whatever transactions speech is not necessary, consent being sufficient, a deaf person also can take part in them, because he can understand and consent, as, for example, in lettings and hirings, purchases, and the like.
