DEFINITION OF INFLAMMATION. 



Inflammation consists in a retardation of the flow of blood in 

 the small vessels, which requires an increased action of the large 

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

 terised by increased heat, swelling, pain, and redness, and inter- 

 nally by the first three, the last not being discoverable, though 

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

 when slow, and without very active symptoms. In the acute form 

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

 reaction on the heart's pulsations, known as hardness of the pulse. 

 In the dog the healthy pulsations are from 90 to 100 in the min- 

 ute, which may be taken as the standard of health;- the arterial 

 pulse may be felt on the inside of the arm above the knee ; or, by 

 putting the hand against the lower part of the chest, the contrac- 

 tions of the heart may be readily felt. In different breeds, how- 

 ever, there is considerable variation in the pulsations of the heart.
