lungs. It is rarely found as an independent 

 disease, but usually found associated with 

 pneumonia and is no doubt caused by the same 

 disease germ. It may occur as an independent 

 disease due to a fractured rib or a deep punc- 

 tured wound. 



When the animal is first noticed it has a 

 great deal of pain. It does not move around 

 much and when it does it will move as though 

 foundered. The breathing is very fast, but 

 is mostly abdominal and very shallow. The 

 ribs are fixed. Movements of the animal give 

 pain. Pressure between the ribs causes the 

 animal to evince pain. A short grunting 

 sound is heard most times in breathing and 

 the expiration is much longer than the inspira- 

 tion. The muzzle is hot and dry and the ap- 

 petite is absent. The animal is constipated 

 and the temperature will be around 105 or 106 

 degrees Fahrenheit. If the ear is placed over 

 the chest cavity a hoarse rasping sound is 

 heard and this is caused by the rubbing to- 

 gether of the two dry inflamed surfaces. After 

 a couple of days the temperature drops to 103 

 or 104 degrees and the animal begins to eat 

 and secretions of the serous membranes begin 

 to fill up the chest cavity and the sounds be- 

 come less harsh as the cavity fills up. If 

 medicinal treatment can not stimulate the ab- 

 sorption of this fluid in the cavity, the animal 

 gradually grows weaker, the breathing shorter
