DISEASES OF THE LUNGS. 571 



body, the legs hand-rubbed and bandaged, warm water 

 clysters given, and a large mustard poultice applied to the 

 chest. The application of mustard should not be made 

 according to the frequent practice of tormenting the animal, 

 with a little rubbing on the sides of the chest. The plan to 

 follow is, to take a pound, or even two, of good mustard and 

 place it on a sheet. The latter should be folded so as not to be 

 broader than the chest, but to wrap round the body once or 

 twice. Having placed the mustard so as to form a good 

 thick poultice with boiling water, it is applied against the 

 lower part of the chest, being spread out a little on either 

 side. The sheet is then fixed by ropes, rollers, or sewing, as 

 most convenient, and care is taken that the mustard is fairly 

 applied to the skin. This is left on for three or four hours 

 at least, until a considerable oedema has occurred beneath 

 the skin. The animal is greatly relieved, and never blemished 

 by this method of treatment. 



Doses of nitre, liquor ammonise acctatis, and, if necessary, 

 a purgative, may be needed to follow up the treatment ; but 

 unless death occurs at an early stage, I find the simple 

 remedies above described amply sufficient. " 



BRONCHITIS. 



Inflammation of the bronchial tubes is a frequent disorder 

 of our domestic animals. I have especially studied it in the 

 horse, ox, and dog, and though sheep, pigs, and other ani- 

 mals suffer severely from this disease, individual cases have 

 been less watched in them. 



Causes. An attack of bronchitis may supervene on a 

 severe sore throat, or the pulmonary congestion just described 

 often results in a severe inflammation of the air-passages. I 

 have seen far more bronchitis in the three animals above 

 mentioned, since I have been practising in Edinburgh, than
