Again, it is well known today to students of the matter that the mind exerts a profound influence upon all vital function, and it seems that no one should be permitted to meddle with a man's health until he has been made thoroughly acquainted with what- ever is well established regarding the relationships existing between mind and body.

But what proportion of the physicians now in service have any exact knowledge, so that they can use it advantageously, of the constitution of the human mind, and how it affects vital pro- cesses in its varied states and functionings ? If a law could be enacted requiring that every youth before he would be decorated with the badge of physician should, in addition to what is now commonly required of him, first master all that is known respecting the evolution of the human body and the influence of thought and feeling upon vital function, who can estimate to what extent society would be benefited by this one act ?
