[IDEM libro undecimo ex Cassio. ] §50.16.112.prLitus publicum est eatenus, qua maxime fluctus exaestuat.
[THE SAME, in the eleventh book of his commentary on Cassius.] A public shore extends as far as the wave surges at its highest.
idemque iuris est in lacu, nisi is totus priuatus est.
And the same rule of law applies to a lake, unless it is entirely private.
