DISEASES OF THE LUNGS. 139 



toms to a certain extent, but they will undoubtedly- reappear in their 

 intensity the first time the animal overloads the stomach or is al- 

 lowed food of bad quality. Clover hay or bulky food which contains 

 but little nutriment have much to do with the cause of the disease, 

 and therefore should be entirely omitted when the animal is affected, 

 as well as before. It has been asserted that the disease is unknown 

 where clover hay is never used. The diet should be confined to food 

 of the best quality and in the smallest quantity. The bad effect of 

 moldy or dusty hay, fodder, or food of any kind can not be over- 

 estimated. A small quantity of the best hay once a day is sufficient. 

 This should be cut and dampened. The animal should invariably be 

 watered before feeding ; never directly after a meal. The animal 

 should not be worked immediately after a meal. Exertion, when the 

 stomach is full, invariably aggravates the symptoms. Turning on 

 pasture gives relief. Carrots, potatoes, or turnips chopped ard 

 mixed with oats or corn are a good diet. Half a pint to a pint of 

 thick, dark molasses with each feed is useful. 



Arsenic is efficacious in palliating the symptoms. It is best ad- 

 ministered in the form of the solution of arsenic, as Fowler's solu- 

 tion or as the white powdered arsenious acid. Of the former the 

 dose is 1 ounce to the drinking water three times daily. Of the 

 latter one may give 3 grains in each feed. These quantities may be 

 cautiously increased as the animal becomes accustomed to the drug. 

 If the bowels do not act regularly, a pint of raw linseed oil may be 

 given once or twice a month, or a handful of Glauber's salt may 

 be given in the feed twice daily, so long as necessary. It must, 

 however, be borne in mind that all medical treatment is of secondary 

 consideration ; careful attention paid to the diet is of greatest impor- 

 tance. Broken-winded animals should not be used for breeding pur- 

 poses. A predisposition to the disease may be inherited. 



CHRONIC COUGH. 



A chronic cough may succeed the acute diseases of the respiratory 

 organs, such as pneumonia, bronchitis, laryngitis, etc. It accom- 

 panies chronic roaring, chronic bronchitis, broken wind. It may 

 succeed influenza. As previously stated, cough is but a symptom 

 and not a disease in itself. Chronic cough is occasionally associated 

 with diseases other than those of the organs of respiration. It 

 may be a symptom of chronic indigestion or of worms. In such 

 cases it is caused by a reflex nervous irritation. The proper treat- 

 ment in all cases of chronic cough is to ascertain the nature of the 

 disease of which it is a symptom, and then cure the disease if possible, 

 and the cough will cease. 



The treatment of the affections will be found under their appro- 

 priate heads, to which the reader is referred.
