blood tint fades away, and matters return to their previous 

 state of quiescence. 



In the opposite condition, that of pallor, which is as- 

 sociated with the emotion of fear, especially sudden 

 shock, the skin becomes pale, the lips lose their bright- 

 ness, and often a sense of coldness even to shivering is 

 felt. Here we have a temporary diminution in the flow 

 of blood the brain acting upon the heart and the 

 surface being less supplied with blood. A similar 

 effect is produced in fainting. The rationale of the 

 fainting state is a temporary failure in the action of the 

 heart, and the brain failing to receive its full supply of 

 blood, unconsciousness supervenes. The bloodlessness 

 of the surface typifies the bloodlessness of the brain. 

 The return of blood to all these parts, and the resto- 

 ration from the fainting state is accompanied by a sense 

 of heat and fulness. 



And so again the final hue of death, in all time obvious 

 and striking "pallida mors" is due to the final beats 

 of the heart, and dying contractions of the arteries send- 

 ing the life-stream slowly on its way to stagnate in the 

 veins. The emptiness of the arteries and the capillaries 

 gives a pallor to the surface, which the laden veins do 

 not overcome.
