The Lecturer said that he was delighted to see so large a gathering. (_Cheers._) They quite reminded him of the clients who thronged his passage on the first day of Term, waiting for his chamber doors to open. (_Laughter._) There was nothing in the remark he had just made to provoke merriment. He wished it to be clearly understood that he appealed to their reason. (_Cheers._) It had been objected that some of the entertainments given at what had been called political pic-nics had nothing to do with the reasoning faculties of the spectators. This he emphatically denied. (_Applause._) Without wasting further of their time--(_"No, no!" "Go on."_)--he would come to his first illustration--the Bounding Brothers of Bohemia. (_Great cheering._) It was advisable that the bodies as well as the minds of children educated by the School-Boards should receive attention. Their bodies should be brought to as near perfection as possible; every muscle should be brought into play. To explain his meaning, he called upon the Bounding Brothers of Bohemia to illustrate the poetry of motion. Upon this, five gentlemen in tights (understood to be the athletic kindred to whom the Lecturer had referred) performed a series of feats of strength, which included standing on one another's heads, jumping through hoops, and turning quadruple somersaults. After their performances were over Mr. BRIEFLESS resumed. The Lecturer said: He next wished to appeal to their reason--to challenge, so to speak, their senses on the power of foreign opinion. It was asserted that an Englishman cared only for his native land and the Press appertaining thereto. Now he (the Lecturer) had the greatest respect for the English Press--(_cheers_)--still he found that some of our foreign contemporaries were nearly as good. (_"Hear, hear!"_) He wished to introduce the Signora MANTILLA from Spain--(_applause_)--who had consented to sing a political song in Spanish, emphasizing her opinions by a dance after each verse. (_Great cheering._) The Signora MANTILLA then gave a demonstration, which was much appreciated. The Lecturer resumed. He said he had not insulted their intelligence by asking them if they understood Spanish. Of course, they did. (_Loud laughter._) He was quite sure that the Signora's third verse and accompanying dance must have convinced everyone of the advantages of Fair Trade. (_Laughter._) He saw no reason for merriment. (_Renewed laughter._) He had now come to that important subject Bi-metallism. (_Cheers._) They had been told that whereas speech was silver, silence was golden. (_"Hear, hear!"_) To show the advantage of silver (represented by speech), the Blue-eyed Nigger would give a native song accompanied on his own banjo. (_Loud applause._) The Blue-eyed Nigger then favoured the company with one of his characteristic ditties.
