[IULIANUS libro singulari de ambiguitatibus. ] §32.0.62.prQui duos mulos habebat ita legauit: 'mulos duos, qui mei erunt cum moriar, heres dato': idem nullos mulos, sed duas mulas reliquerat.
[JULIANUS, from his single book on ambiguities.] person who owned two male mules bequeathed them as follows: 'Let my heir give the two male mules which shall be mine when I die': the same person left no male mules, but two female mules.
respondit Seruius deberi legatum, quia mulorum appellatione etiam mulae continentur, quemadmodum appellatione seruorum etiam seruae plerumque continentur.
Servius answered that the legacy was due, because under the designation of 'male mules' female mules also are contained, just as under the designation of 'slaves' female slaves also are generally contained.
id autem eo ueniet, quod semper sexus masculinus etiam femininum sexum continet.
This, moreover, arises from the fact that the masculine gender always contains the feminine gender as well.
