42 THE PRACTICE OF VETERINARY MEDICINE. 



PLEURODYNIA. 



Definition. — A rheumatic inflammation of the walls of the 

 thorax. This condition is sometimes mistaken for pleurisy. 



Causes. — Exposure to cold and wet, and more particularly 

 if the animal be debilitated from previous disease, etc. 



Sym])toms. — The symptoms are very similar to those of 

 pleurisy. The animal appears to be in great pain ; respira- 

 tions are short and painful; pressure on the intercostal 

 spaces causes the patient to grunt, and evidently produces 

 greater pain than would follow a similar proceeding in 

 pleurisy. One or both sides may be aff'ected. Some 

 writers say that the left side is afl'ected oftener than the 

 right. The circulation is not affected, the pulse being in a 

 normal condition. Auscultation reveals no evidence of 

 internal disease, the sounds being of a normal character. 



Treatment. — Hot applications to the sides of the thorax 

 are good, as hot water, or cloths wrung out of hot water ; 

 counter-irritation, or anodyne applications, as camphorse, 

 opii tr., tr. arnica, mont., pars equales, may be employed, 

 to which ol. terebinth., if desired, may be added. Solicit 

 intestinal action by enemas containing ol. terebinth. 



BUONCHITIS. 



Definition. — Bronchitis maybe defined to be an inflamma- 

 tion of the mucous membrane lining the bronchial tubes ; it is 

 sometimes called catarrhal bronchitis. According to whether 

 it attacks the large or small bronchial tubes, is the danger 

 great or small. Bronchitis often occurs in conjunction with 

 pneumonia; there is first heat, and dryness of the mucous 

 membrane, after which an exudate is poured out, which if 

 in the small tubes clogs them up and produces death ; but if 

 the large tubes alone are afl'ected, much danger need not be
