"Ignoramus."
As commonly used nowadays this term is equivalent to "dunce," but it was originally employed as a law term. It is a Latin word, and literally translated means, "we do not know." In former days when a grand jury considered that a bill or indictment was not supported by sufficient evidence to prove the need for a trial, they wrote the word "ignoramus" on the back of it, signifying that they rejected it. The words used in present practice are simply "not a true bill," or "not found." But in course of time the old Latin term was made serviceable, as we have seen, in a new way.
