"Marriage," he said slowly--"Marriage is not for you. It is better that you should face that fact at once. Such a family history as the one you have just related is a standing evidence of selfishness and cruelty. Your parents, your grandparents, outraged a great moral law, and you and others are here to pay the price. You must not follow their example. This handing on of disease must come to an end. You may think that in the case of your possible marriage there might not be children; I will not discuss that point to-day--it is not needful. You are my patient, and you yourself would run a more serious risk of developing the malady as a wife. Even the happiest of married lives has responsibilities, anxieties, physical and mental strains, which might easily prove too much for your mental balance. It would not be fair to a man to bring that dread into his life. Marriage for you would be a cruel and cowardly act. For the man's sake, for your own sake, you must put the idea out of your life." There was a moment's silence in the room, then the girl spoke in a low, faint voice: "Thank you!" she said softly. With a hand that moved in mechanical fashion she took a little paper packet from her muff, laid it down on the corner of the desk, and rose to her feet. "One moment!" cried the doctor hastily. In that room, seated in that chair, it had been his lot to speak many sentences of death, but he had not yet hardened himself to maim a life unmoved. Having dealt his blow, he was anxious to speak a word of comfort to the girl who had said "Thank you," in that quiet voice. His keen, hawk-like face wrinkled into a network of lines as he looked at her across the room.
