One of the oldest and most firmly-rooted beliefs of the race is that which holds that the pregnant mother may, and often does, consciously or unconsciously, impress upon her unborn child certain mental, moral, or physical traits. The majority of persons accept this idea as self-evident, and are able to cite cases within their own personal experience which go to prove the correctness of the popular belief. But certain modern authorities have sought to tear down this belief, and to discredit the general idea. Let us briefly consider both sides of this question. On the side of the generally accepted belief, Riddell says: "The more I study the influence of maternal impressions upon the life, mentality and character of men, the more I am led to believe that the education and moral training that a child receives before it sees the light of day are the most influential, and, therefore, the most important part of its education." Newton says: "A mother may, during the period of gestation, exercise some influence, by her own voluntary mental and physical action, either unwittingly or purposely, in determining the traits and tendencies of her offspring. This is now a common belief among intelligent people. Every observant teacher could doubtless bear witness to the same general facts, and it would be easy to fill a volume with testimonials from various sources illustrative and confirmatory of the law under discussion. Such facts establish beyond question the conviction that the mother has it largely in her power to confer on her child such a tendency of mind and conformation of brain as shall not only facilitate the acquisition of knowledge in any specific direction, but make it certain that such knowledge will be sought and acquired." Dr. Fordyce Baker says: "The weight of authority must be conceded to be in favor of the idea that maternal impressions may effect the growth, form and character of a forming child." Dr. Rokitansky says: "The question whether mental emotions do influence the development of the child must be answered 'Yes!'" Dr. Brittain says: "The singular effects produced on the unborn child by the sudden mental emotions of the mother are remarkable examples of a kind of electrotyping on the sensitive surface of living forms. It is doubtless true that the mind's action in such cases may increase or diminish the molecular deposits in the several portions of the system. The precise place which each separate particle assumes may be determined by the influence of thought or feeling. If, for example, there exists in the mother any unusual tendency of the vital forces to the brain at the critical period, there will be a similar cerebral development and activity in the offspring."
