Eminent advocates have almost invariably possessed qualities that would have made them successful mimics on the stage. For his mastery of oratorical artifices Alexander Wedderburn was greatly indebted to Sheridan, the lecturer on elocution, and to Macklin, the actor, from both of whom he took lessons; and when he had dismissed his teachers and become a leader of the English bar he adhered to their rules, and daily practised before a looking-glass the facial tricks by which Macklin taught him to simulate surprise or anger, indignation or triumph. Erskine was a perfect master of dramatic effect, and much of his richly-deserved success was due to the theatrical artifices with which he played upon the passions of juries. At the conclusion of a long oration he was accustomed to feign utter physical prostration, so that the twelve gentlemen in the box, in their sympathy for his sufferings and their admiration for his devotion to the interests of his client, might be impelled by generous emotion to return a favorable verdict. Thus when he defended Hardy, hoarseness and fatigue so overpowered him towards the close of his speech, that during the last ten minutes he could not speak above a whisper, and in order that his whispers might be audible to the jury, the exhausted advocate advanced two steps nearer to their box, and then extended his pale face to their eager eyes. The effect of the artifice on the excited jury is said to have been great and enduring, although they were speedily enlightened as to the real nature of his apparent distress. No sooner had the advocate received the first plaudits of his theatre on the determination of his harangue, than the multitude outside the court, taking up the acclamations which were heard within the building, expressed their feelings with such deafening clamor, and with so many signs of riotous intention, that Erskine was entreated to leave the court and soothe the passions of the mob with a few words of exhortation. In compliance with this suggestion he left the court, and forthwith addressed the dense out-door assembly in clear, ringing tones that were audible in Ludgate Hill, at one end of the Old Bailey, and to the billowy sea of human heads that surged round St. Sepulchre's Church at the other extremity of the dismal thoroughfare.
