BIÆUM, suus, in Rhetoric, denotes a kind of counter argument, whereby something alleged for the adversary is retorted against him, and made to conclude a different way: for instance, Ocidisti, quia adstitisti interfecto.—Buam, Immo quia adstiti interfecto, non occidi; nam si id esset, in fugam me concessissem. "You killed the person, because you were found standing by his body. Buam, Rather I did not kill him because I was found standing by his body; since, in the other case, I should have fled away."
