In his youth he had occupied himself much with comparative anatomy and physiology. His predilection for these studies had greatly sharpened his observation, and he noted many things that escaped the eyes of better than ordinary observers. Amongst other kinds of things to which he kept his eyes open, he was very quick at noting instances of the strange persistency with which Nature perpetuates minute peculiarities, carrying them on from generation to generation. Occupied with Amanda, a certain imperfection in one of the curves of the outer ear attracted his attention. It is as rare to see a perfect ear as to see a perfect form, and the varieties of unfinished curves are many; but this imperfection was very peculiar. At the same time it was so slight, that not even the eye of a lover, none save that of a man of science, alive to minutest indications, would probably have seen it. The sight of it startled Faber not a little; it was the second instance of the peculiarity that had come to his knowledge. It gave him a new idea to go upon, and when the child suddenly opened her eyes, he saw another face looking at him out of hers. The idea then haunted him; and whether it was that it assimilated facts to itself, or that the signs were present, further search afforded what was to him confirmation of the initiatory suspicion. Notwithstanding the state of feebleness in which he found Mr. Drake the next morning, he pressed him with question upon question, amounting to a thorough cross-examination concerning Amanda's history, undeterred by the fact that, whether itself merely bored, or its nature annoyed him, his patient plainly disrelished his catechising. It was a subject which, as his love to the child increased, had grown less and less agreeable to Mr. Drake: she was to him so entirely his own that he had not the least desire to find out any thing about her, to learn a single fact or hear a single conjecture to remind him that she was not in every sense as well as the best, his own daughter. He was therefore not a little annoyed at the persistency of the doctor's questioning, but, being a courteous man, and under endless obligation to him for the very child's sake as well as his own, he combated disinclination, and with success, acquainting the doctor with every point he knew concerning Amanda. Then first the doctor grew capable of giving his attention to the minister himself; whose son if he had been, he could hardly have shown him greater devotion. A whole week passed before he would allow him to go home. Dorothy waited upon him, and Amanda ran about the house. The doctor and she had been friends from the first, and now, when he was at home, there was never any doubt where Amanda was to be found. The same day on which the Drakes left him, Faber started by the night-train for London, and was absent three days.
