Certificate, trial by

This is a mode of trini now little in use; it is resorted to in cases where the fact in issue lies out of the cognizance of the court, and the judges, in order to determine the question, are obliged to rely upon the solemn averment or information of persons in such a station as affords them the dearest and most competent knowledge of the truth.
