RULE III.—APPOSITION.
A Noun or a personal Pronoun used to explain a preceding noun or pronoun, is put, by apposition, in the same case: as, "But it is really I, your old friend and neighbour., Piso, late a dweller upon the Coelian hill, who am now basking in the warm skies of Palmyra."—Zenobia.
"But he, our gracious Master, kind as just,
Knowing our frame, remembers we are dust."—Barbauld.
