[GAIUS libro sexto ad edictum prouinciale. ] §5.3.21.prDeperditum intellegitur, quod in rerum natura esse desiit: deminutum uero, quod usucaptum esset et ob id de hereditate exiit.
[GAIUS in the sixth book on the Provincial Edict] By 'perished' is understood that which has ceased to exist in the nature of things; but by 'deteriorated', that which has been acquired by usucapion and for that reason has departed from the inheritance.
