4. Agreement in Person. With compound subjects of different persons the verb always takes the first person rather than the second, and the second rather than the third; as,—
sī tū et Tullia valētis, ego et Cicerō valēmus, if you and Tullia are well, Cicero and I are well.
5. Agreement in Gender. With subjects of different genders the participle in the compound tenses follows the same principles as laid down for predicate adjectives. See [§ 235], B, 2.
VOICES.
[256]. 1. The Passive Voice sometimes retains traces of its original middle or reflexive meaning; as,—
ego nōn patiar eum dēfendī, I shall not allow him to defend himself.
2. In imitation of Greek usage many perfect passive participles are used by the poets as indirect middles, i.e. the subject is viewed as acting not upon itself, but as doing something in his own interest; as,—
vēlātus tempora, having veiled his temples.
a. Occasionally finite forms of the verb are thus used; as,—
tunicā indūcitur artūs, he covers his limbs with a tunic.
