_Influence of mind of mother on form and color of infant._--There are numerous facts on record which prove that _habitual_, long-continued mental conditions of the mother at an early period of pregnancy, induce deformity or other abnormal development of the infant. Professor William A. Hammond of New York relates the following striking case, which occurred in his own experience, and which scarcely admits of a doubt as to the influence of the maternal mind over the physical structure of the fœtus. A lady in the third month of her pregnancy was very much horrified by her husband being brought home one evening with a severe wound of the face, from which the blood was streaming. The shock to her was so great that she fainted, and subsequently had a hysterical attack, during which she was under Dr. Hammond's care. Soon after her recovery she told him that she was afraid her child would be affected in some way, and that even then she could not get rid of the impression the sight of her husband's bloody face had made upon her. In due time the child, a girl, was born. She had a dark red mark upon the face, corresponding in situation and extent with that which had been upon her father's face. She also proved to be idiotic. Professor Dalton of New York states that the wife of the janitor of the College of Physicians and Surgeons of that city, during her pregnancy, dreamed that she saw a man who had lost a part of the ear. The dream made a great impression upon her mind, and she mentioned it to her husband. When her child was born, a portion of one ear was deficient, and the organ was exactly like the defective ear she had seen in her dream. When Professor Dalton was lecturing upon the development of the fœtus as affected by the mind of the mother, the janitor called his attention to the foregoing instance. The ear looks exactly as if a portion had been cut off with a sharp knife.
