[IDEM libro octauo ad Quintum Mucium. ] §50.16.122.prSeruius ait, si ita scriptum sit: 'filio filiisque meis hosce tutores do', masculis dumtaxat tutores datos, quoniam a singulari casu hoc 'filio' ad pluralem uidetur transisse continentem eundem sexum, quem singularis prior positus habuisset.
[THE SAME, in the eighth book on Quintus Mucius.] Servius says that if it is written thus: "I give these guardians to my son and my sons," guardians are given only to the males, because this word "to the son" in the singular case seems to have passed to a plural that contains the same sex which the preceding singular, having been placed first, would have had.
sed hoc facti, non iuris habet quaestionem: potest enim fieri, ut singulari casu de filio senserit, deinde plenius omnibus liberis prospexisse in tutore dando uoluerit.
But this is a question of fact, not of law; for it can happen that in the singular case he had the son in mind, and then, in appointing a guardian, wished to provide more fully for all his children.
quod magis rationabile esse uidetur.
And this indeed seems to be more reasonable.
