Common Cough. 151 



ting liniment, or ointment of iodine. The horse should 

 at all times have the free use of his head and neck, or the 

 best treatment might fail. Should the cause of roaring 

 evidently exist (below the fauces) either in the bronchii, 

 trachea, or lungs, the operation of trachetomy may be 

 preferred, which consists in making an opening into the 

 trachea, and through it inserting a tube, which may be 

 worn for any length of time, by taking the precaution to 

 cleanse it occasionally. See Tracheotomy. 



COMMON COUGH. 



Cough is present, and often causes annoyance, in ca- 

 tarrh, laryngitis, bronchitis, strangles, horse ail, &c. Is 

 present also in cases of deranged digestive organs, and 

 when a quantity of worms are present in the digestive 

 cavity. A common cough may attend various forms of 

 disease. In cases of a catarrhal character, when a quan- 

 tity of mucus accumulates in the respiratory passages, 

 the act of coughing ejects it, and thus relieves the ani- 

 mal ; therefore, a cough of this kind may be salutary 

 rather than otherwise, and in that event ncods no treat- 

 ment. 



A sympathetic cough can only be cured by directing 

 our remedies to the seat of the malady ; that cured, the 

 cough ceases. 



It does not interfere with the treatment of any disease 

 to use simple remedies to mitigate a cough, if it cause the 

 patient some annoyance ; in this view I use powdered 

 slippery elm, Indian turnip, powdered skunk cabbage, 

 caraway seeds, of each 4 ounces. Dose, one half ounce 

 twice a day in grueL 



If the cough continues after the disappearance of pul- 

 monary diseases, dissolve 1 ounce of balsam of fir in 

 2 ounces of the sweet spirits of nitre, add 4 ounces of 

 the syrup of garlic. Dose, one ounce, night and morn- 

 ing, given in gruel. 



CHRONIC COUGH. 



Chronic cough is generally caused by long continued 

 or neglected catarrh, or sore throat.
