Afterward, when the baby was born, one of the child's eyes was marked by the color and fire of the dashing Spaniard's eyes, while its other eye was a calmish blue-gray eye. This was all the more remarkable as neither of the parents of the child had such eyes. Was it a case of maternal impression? Upon investigation I found that the grandparents of the baby's mother had just such eyes as the baby. The grandfather's were big, dark, flashing eyes, and the grandmother's the mild, blue-gray eyes. So 'bang!' went the theory of mental impression, and in its place came the physical law of reversion." I do not wish to be misunderstood as claiming that a mother's condition during pregnancy has no effect on the child, and that she need therefore take no precautions and pay no particular attention to her health and her feelings. This is not so. But what I do want to convey is this: That if a mother's health during pregnancy is bad, if she is a prey to worry and anxiety, if she was subjected to great fright or to a shock, then the child's general health may suffer. It may be stillborn, or the mother may have a miscarriage. But it will not produce those specific marks, deformities and monstrosities which are commonly supposed to be the results of maternal impressions. If I lay somewhat special stress upon the subject of maternal impressions, it is because I pity the poor mothers and want to spare them as much as possible unnecessary worry and anxiety. Besides I want them to believe in the truth and not in error.
