carditis. If the inflammation occnrs in several portions of 

 the heart, several sounds may be perceptible which vary in 

 pitch, intensity and volume. 



The pulse is always accelerated, although its frequency is 

 extremely variable in. different cases ; it is frequently arhythmi- 

 cal, irregular and intermittent ; the intermissions are sometimes 

 so frequent that the number of heart beats is as much as twice 

 that of the pulse beats. At the commencement of light cases, 

 the pulse is strong and even vigorous in relation to the rate, 

 but later, and in severe cases from the first, it is weaker and 

 soft. The character of 

 the pulse depends in 

 part upon the localiza- 

 tion of the disease (see 

 valvular diseases) ; for 

 instance in inflamma- 

 tion of the aortic valves 

 it is bounding (see Fig. 

 190). 



In correspondence 

 with the intensity of 

 the disease circulatory 

 disturbances develop 

 which are manifested 

 by cyanosis, fullness of 

 the veins, negative 

 venous pulse, and by 

 frequent or difficult res- 

 piration, and which may 

 be aggravated into as- 

 phyctic attacks on the

severe pulmonary hy- 

 peremia is in many cases a bloody discharge from the nose 

 which may be accompanied by symptoms of pulmonary edema. 

 Moreover* edemas sometimes develop quite early in various 

 parts of the body, for instance, on the limbs and on the lower 

 portions of the trunk. Occasionally, and particularly in hogs, 

 a decided weakness of the hindquariter, or even of one posterior 

 extremity, is observed, which is due either to a stenosis of 

 the aortic opening, or to a general embolic obstruction of the 

 arteries, or to the debility which follows upon the severe general 

 disease.
