164 PRACTICE OF EQUINE MEDICINE. 



Local treatment. 



During the stage of congestion, especially in city practice 

 where horses are overworked and their heart is weak, strong English 

 mustard (mixed with water to make a paste) can be well rubbed 

 in over the affected lung and then covered with a sheet of paper. 

 Tie the animal up for about two hours, after which he should be 

 placed in a box stall, blanketed and legs bandaged. Give good 

 fresh air but do not allow drafts. 



If mustard is not used an oil-silk jacket is beneficial in some 

 cases; or where this is not available cotton batten covering the 

 sides held in place with a wide bandage may prove useful. 



The animal should not receive forced exercise under two 

 weeks as a rule, on account of weakening the heart. 



LOBTTLAK PNEUMONIA. 



Give the synonyms. 



Broncho-pneumonia; pneumonia lobularis; it is sometimes 

 called catarrhal pneumonia. 



Define lobular pneumonia. 



It is essentially an inflammation of the terminal bronchi and 

 the air-cells which make up a pulmonary lobule, and thus the name 

 broncho-pneumonia. 



What is the aetiology? 



It is secondary in the great majority of cases. It may be seen 

 in cases of purpura hemorrhagica, glanders, pyaemia, and the like. 



It may arise from emboli in the capillaries of the pulmonary 

 artery; these emboli are formed from thrombi which break up and 

 get in the circulation of the capillaries of the pulmonary artery 

 and block them up and stop the circulation. 



Give the morbid anatomy. 



The pathology is about the same as lobar pneumonia, except 

 that the lobular structure is involved in this disease, whereas, in 

 lobar pneumonia, the lobes are affected. 



It seems to be restricted to certain spots or patches of con- 

 solidation. 



What are the symptoms? 



Most cases show symptoms of acute bronchitis, and, by exten- 

 sion, involve the air-cells of the lobules ; the temperature rises ; the-
