To her mamma and others her fits of timidity or terror were sufficiently accounted for by her "sensitiveness" or the "excitability of her nature"; but these explanatory phrases required conciliation with much that seemed to be blank indifference or rare self-mastery. Heat is a great agent and a useful word, but considered as a means of explaining the universe it requires an extensive knowledge of differences; and as a means of explaining character "sensitiveness" is in much the same predicament. But who, loving a creature like Gwendolen, would not be inclined to regard every peculiarity in her as a mark of preeminence? That was what Rex did. After the Hermione scene he was more persuaded than ever that she must be instinct with all feeling, and not only readier to respond to a worshipful love, but able to love better than other girls. Rex felt the summer on his young wings and soared happily.
