A, the first letter of the English and most other alphabets, is frequently used as an abbreviation, (q.v.) and also in the marks of schedules or papers, as schedule A, B, C, &c. Among the Romans this letter was used in criminal trials. The judges were furnished with small tables covered with wax, and each one inscribed on it the initial letter of his vote; A, when he voted to absolve the party on trial; C, when he was for condemnation; and N L, (non liquet) when the matter did not appear clearly, and be desired a new argument.
