detested all games of chance. His views of men and manners were singularly correct, and denoted a well-balanced brain. It was only where his affections were concerned that he could be called in any way extravagant; but this would be accounted rather a virtue than a vice. His recreations were intellectual, and he sought pleasure and happiness only in his home and in association with books and his wife and child. What judgment would you, from a distance, pass upon such a man? What but that of entire approval? But I was in daily contact with him, and signs were visible to me which greatly disturbed me. To speak plainly, I doubted Gabriel Carew's perfect sanity! This was a matter of most serious moment. If Carew were not sane, his disease, so far as I could judge, was of a harmless form. The proof of this lay in his affection for those of his blood, and--which, in evidence is, in my opinion, quite as strong--in his tenderness to animals and birds. But I have to a certainty established not only that insanity is hereditary, but that what is harmless in the parent may become destructive in the child. Mildred was Carew's daughter, and to all appearance as free from any touch of insanity as the most healthful of human beings. But the germ must be in her, to be transmitted to her children--to Reginald's children if he married her. This consideration impelled me to secret action in the way of inquiry. It would have been, useless to appeal to Reginald, and to set before him the probable consequences of such an union. My counsel would have fallen upon idle ears. My duty, however, was clear. It was for me to protect him. Instead of listening uninterruptedly to the confidences imparted to me by Carew, I prompted, probed and asked questions, and thus learnt much which might otherwise not have come to my knowledge. Considering the motive by which I was impelled, the investigation I was pursuing was of an exceedingly delicate nature, but to my surprise, Carew met--nay, anticipated--me with a most surprising frankness. He made no attempt to avoid the subject, and the interest he evinced in it seemed to exceed my own. He spoke much of himself--not in direct connection with hereditary insanity, but as though there was that in his life before the death of his parents which it would be a relief to him to clear up. He gave me a circumstantial account of all the incidents of those early years, taking pains to recall the most trifling detail bearing upon his youth. "It is a strange pleasure to me," he said, "to be able to unbosom myself so freely. My wife is acquainted with much I have imparted to you. There was never
