with the ordinary and tonic contraction of the small 

 arteries of that part. These vessels, in consequence, be- 

 come at such times more or less relaxed, and are in- 

 stantly filled with arterial blood. This tendency will 

 have been much strengthened, if frequent attention has 

 been paid during many generations to the same part, 

 owing to nerve-force readily flowing along accustomed 

 channels, and by the power of inheritance. Whenever 

 we believe that others are depreciating or even consid- 

 ering our personal appearance, our attention is vividly 

 directed to the outer and visible parts of our bodies ; and 

 of all such parts we are most sensitive about our faces, 

 as no doubt has been the case during many past genera- 

 tions. Therefore, assuming for the moment that the cap- 

 illary vessels can be acted on by close attention, those of 

 the face will have become eminently susceptible. Through 

 the force of association, the same effects will tend to fol- 

 low whenever we think that others are considering or 

 censuring our actions or character.

 who, by continually watching and counting his own pulse, 

 at last caused one beat out of every six to intermit. On 

 the other hand, my father told me of a careful observer, 

 who certainly had heart-disease and died from it, and 

 who positively stated that his pulse was habitually irregu- 

 lar to an extreme degree ; yet to his great disappointment 

 it invariably became regular as soon as my father entered 

 the room.
