"My little Jack is so fond of me that he cannot bear to see me show attention to any other child. It is really amusing how displeased he gets. He will push the other child away, climb into my lap, and almost smother me with kisses. If I persist in paying attention to somebody else, he will pout in the cutest way until I take him in my arms again." It may, to be sure, be difficult at times to refrain from smiling at the absurd behaviour of jealous children. Just the same, jealousy is never a smiling matter and is always something which parents should try to root out without delay. The jealous child, if uncorrected, is all too likely to grow into a jealous adult, with tendencies which bring misery to himself, and which, if it becomes a question of sex-jealousy, may bring death to others. The parent who fails to attack jealousy when it first shows itself need not be surprised at any distortion of character or vagary of conduct that appears in later life. Jealousy, indeed, may have strange and startling physical consequences. Here, for example, is a story from the experience of a veteran physician: "I was once summoned to visit a lady who was represented as being very ill. On my arrival I was shown to the so-called sick-room, where three persons were present--an old lady, her daughter, and the daughter's husband. All of them seemed in good health. When I inquired which was my patient, there was silence for a moment. Then the daughter said: "'I am the patient, and my complaint is jealousy. I am jealous of my husband, and if you do not give me something to relieve me I shall go out of my mind.' "This, on the face of it, seemed preposterous. She was a tall, fair, beautiful woman of about thirty. The husband, on the contrary, was several years older, a short, swarthy, plain man. It seemed to me more reasonable to suppose that he might have cause to be jealous of his wife, rather than she of him. But she persisted in her statement, and declared that she had good reason to feel jealous. "The husband insisted he had done nothing to justify her jealousy. She reasserted he had. In the midst of an outburst, distressing to listen to, she fell into a queer fit. With rhythmic regularity, she went through various spasmodic convulsions. At one moment she would stand at full length, her body arched forward. The next instant she was in a sitting position, with her legs drawn up, her hands clutching her throat, and a guttural noise coming from her mouth. Then she would wildly throw her arms and legs around; after which she would rise to go through the same performance.
