application of scientific reason to the definition and enforcement of rights, still goes on; but with constant gains on the side of the reformers, all of whom with one consent confess that no general and complete reconstruction of legal doctrine as a science is possible, except upon the lines laid down by Bacon. The most memorable case in which Bacon was employed to represent the Crown during Elizabeth's life was the prosecution of the Earl of Essex for treason. Essex had been Bacon's friend, patron, and benefactor; and as long as the earl remained faithful to the Queen and retained her favor, Bacon served him with ready zeal and splendid efficiency, and showed himself the wisest and most sincere of counselors. When Essex rejected his advice, forfeited the Queen's confidence by the follies from which Bacon had earnestly striven to deter him, and finally plunged into wanton and reckless rebellion, Bacon, with whom loyalty to his sovereign had always been the supreme duty, accepted a retainer from the Crown, and assisted Coke in the prosecution. The crime of Essex was the greatest of which a subject was capable; it lacked no circumstance of aggravation; if the most astounding instance of ingratitude and disloyalty to friendship ever known is to be sought in that age, it will be found in the conduct of Essex to Bacon's royal mistress. Yet writers of eloquence have exhausted their rhetorical powers in denouncing Bacon's faithlessness to his friend. But no impartial reader of the full story in the documents of the time can doubt that throughout these events Bacon did his duty and no more, and that in doing it he not merely made a voluntary sacrifice of his popularity, but a far more painful sacrifice of his personal feelings.
