"You interpret my own thoughts when they have turned towards marriage. But what is there in Lilian Ashleigh that should mar the picture you have drawn?" "What is there in Lilian Ashleigh which in the least accords with the picture? In the first place, the wife of a young physician should not be his perpetual patient. The more he loves her, and the more worthy she may be of love, the more her case will haunt him wherever he goes. When he returns home, it is not to a holiday; the patient he most cares for, the anxiety that most gnaws him, awaits him there." "But, good heavens! why should Lilian Ashleigh be a perpetual patient? The sanitary resources of youth are incalculable. And--" "Let me stop you; I cannot argue against a physician in love! I will give up that point in dispute, remaining convinced that there is something in Lilian's constitution which will perplex, torment, and baffle you. It was so with her father, whom she resembles in face and in character. He showed no symptoms of any grave malady. His outward form was, like Lilian's, a model of symmetry, except in this, that, like hers, it was too exquisitely delicate; but when seemingly in the midst of perfect health, at any slight jar on the nerves he would become alarmingly ill. I was sure that he would die young, and he did so." "Ay, but Mrs. Ashleigh said that his death was from brain-fever, brought on by over-study. Rarely, indeed, do women so fatigue the brain. No female patient, in the range of my practice, ever died of purely mental exertion." "Of purely mental exertion, no; but of heart emotion, many female patients, perhaps? Oh, you own that! I know nothing about nerves; but I suppose that, whether they act on the brain or the heart, the result to life is much the same if the nerves be too finely strung for life's daily wear and tear. And this is what I mean, when I say you and Lilian will not suit. As yet, she is a mere child; her nature undeveloped, and her affections therefore untried. You might suppose that you had won her heart; she might believe that she gave it to you, and both be deceived. If fairies nowadays condescended to exchange their offspring with those of mortals, and if the popular tradition did not represent a fairy changeling as an ugly peevish creature, with none of the grace of its parents, I should be half inclined to suspect that Lilian was one of the elfin people. She never seems at home on earth; and I do not think she will ever be contented with a prosaic earthly lot. Now I have told you why I do not think she will suit you. I must leave it to yourself to conjecture how far you would suit her. I say this in due season, while you may set a guard upon your impulse; while you may yet watch, and weigh, and meditate; and from this moment on that subject I say no more. I lend advice, but I never throw it away."
