DEFINITION OF INFLAMMATION. 



Inflammation consists in a retardation of the flow of blood 

 through the small vessels; an increased action of the large ones is 

 required to overcome it. When external and visible, it is charac- 

 terized by increased heat, swelling, pain, and redness ; when inter- 

 nally, by the first three, the last not being discerned, though ex- 

 isting. It may be acute when coming on rapidly, or chronic when 

 slow, and v/ithout very active symptoms. In the acute form there 

 is always an increased rapidity of the pulse, with a greater reac- 

 tion of the heart's pulsations, known as hardness of the pulse. In 

 the dog, the healthy pulsations are from 90 to 100 to the minute. 

 This may be taken as the standard of health. The arterial pulse 

 may be felt on the inside of the arm above the knee ; by placing 

 the hand against the lower part of the chest, the contractions of 

 the heart may be readily felt. In different breeds there is, how- 

 ever, considerable variation in the pulsations of the heart.
