than ever before was given by Joseph Priestley more than a hundred years ago to a public not yet prepared for the re ception of ideas so advanced as these. I have said that un his labors by his freedom in pro claiming his broad views Priestly had succeeded in making many enemies; but to no violent outbreak did their wrath give way until July the fourteenth, seventeen hundred and ninety-one. Sitting peacefully in his home at Birmingham, at which place he was now pastor after similar labor at Needham,' Nantwich, and Leeds, librarian and secretary to Lord' Shelburne, and tutor in languages at Warrington Academy, he and his family were aroused from the quietude of their fireside communion by a wild and ominous roar, as of a mighty maddeud bull. Before they could recover from their first surprise, a howling mob of fanactical Englishmen, fired by a religious fanaticism that prevaded all Engand and by the incarnate devil of rapacity and revenge, desirous of showing’ in.some way their disapproval of Priestley’s un- English views on this the anniversary of the downfall of the Bastile, pounced like an enraged lion upon defenceless prey, upon the Priestley home and chapel, burning, pillaging, and destroyingthe works of a lifetime. Library, chapel, labora tory, apparatus, and many valuable specimens perished like somuclx tinder. But while a brutal English mob in an hour ot political madness and religious frenzy could do all this it could not stay the indomitable energy of this genius nor di minish the lustre of his brain-won renown. Aided by friends Priestley and his family were enabled to escape to London and after three years of not too pleasant labor in-charge of a pastorate at the Mill Hall chapel, he set sail on April the fourth, seventeen hundred and ninety four, for America, the home of the oppressed, a refuge from the turmoil, of English life, and a spot in which he might spend the remainder of his alloted years in peace arid quiet. After a tiresome voyage of six weeks duration he landed at Joseph Priestley.
