The Professor was not an unkind man. He really enjoyed making his family happy; and it was his own business if his reward for so doing was that it kept them out of his way. But the success of "The Vital Thing" gave him more than this negative satisfaction. It enlarged his own existence and opened new doors into other lives. The Professor, during fifty virtuous years, had been cognizant of only two types of women: the fond and foolish, whom one married, and the earnest and intellectual, whom one did not. Of the two, he infinitely preferred the former, even for conversational purposes. But as a social instrument woman was unknown to him; and it was not till he was drawn into the world on the tide of his literary success that he discovered the deficiencies in his classification of the sex. Then he learned with astonishment of the existence of a third type: the woman who is fond without foolishness and intellectual without earnestness. Not that the Professor inspired, or sought to inspire, sentimental emotions; but he expanded in the warm atmosphere of personal interest which some of his new acquaintances contrived to create about him. It was delightful to talk of serious things in a setting of frivolity, and to be personal without being domestic. Even in this new world, where all subjects were touched on lightly, and emphasis was the only indelicacy, the Professor found himself constrained to endure an occasional reference to his book. It was unpleasant at first; but gradually he slipped into the habit of hearing it talked of, and grew accustomed to telling pretty women just how "it had first come to him." Meanwhile the success of the Scientific Sermons was facilitating his family relations. His photograph in the _Inglenook_, to which the lady of the note-book had succeeded in appending a vivid interview, carried his fame to circles inaccessible even to "The Vital Thing"; and the Professor found himself the man of the hour. He soon grew used to the functions of the office, and gave out hundred-dollar interviews on every subject, from labour-strikes to Babism, with a frequency which reacted agreeably on the domestic exchequer. Presently his head began to figure in the advertising pages of the magazines. Admiring readers learned the name of the only breakfast-food in use at his table, of the ink with which "The Vital Thing" had been written, the soap with which the author's hands were washed, and the tissue-builder which fortified him for further effort. These confidences endeared the Professor to millions of readers, and his head passed in due course from the magazine and the newspaper to the biscuit-tin and the chocolate-box. VI
