Moments earlier, a young printer named Edward Gilbert Abbott had been rendered unconscious by inhaled ether -- administered by a Boston dentist, William Thomas Green Morton, through a handblown glass device he had invented days before -- and Warren had painlessly removed a tumor from Abbott's neck. When Abbott woke and reported feeling nothing more than "a scratching sensation," the audience understood: the era of surgical agony was over.
