I cannot help picturing in the countenance of the young man I have just spoken of an indefinable but unpleasant impertinence, smoothness, and affectation, which is repulsive to a plain man, and in the countenance of my own pupil a simple and interesting expression which indicates the real contentment and the calm of his mind; an expression which inspires respect and confidence, and seems only to await the establishment of friendly relations to bestow his own confidence in return. It is thought that the expression is merely the development of certain features designed by nature. For my own part I think that over and above this development a man's face is shaped, all unconsciously, by the frequent and habitual influence of certain affections of the heart. These affections are shown on the face, there is nothing more certain; and when they become habitual, they must surely leave lasting traces. This is why I think the expression shows the character, and that we can sometimes read one another without seeking mysterious explanations in powers we do not possess.
