[CELSUS libro uicesimo septimo digestorum. ] §19.1.12.prSi iactum retis emero et iactare retem piscator noluit, incertum eius rei aestimandum est: si quod extraxit piscium reddere mihi noluit, id aestimari debet quod extraxit.
[CELSUS, Digest, Book 27] If I have bought a cast of a net and the fisherman refused to cast the net, the uncertain value of that matter must be assessed; if he refused to hand over to me the fish which he drew out, that which he drew out must be assessed.
