140 DISEASES OF THE RESPIRATORY ORGANS 



as morphia, extract of hyoscyamus, or dilute hydrocyanic acid or 

 cyanide of potassium. When there is fever present, a few doses of antipy- 

 rine (0.5 to 1.0 gramme, twice daily) will generally suffice. 



Tartar emetic, chloride of ammonium, and sulphuretted antimony are 

 of little use; in fact, do more harm than good, as they often destroy the 

 appetite and cause great depression. In the early stages of the disease 

 the cough does not amount to much, but in the later stages, it is constant 

 and very disagreeable, especially at night, and it is in such cases that 

 expectorants are useful to remove the accumulations of mucus. The 

 addition of morphia to the apomorphia solution has the tendency to 

 counteract the emetic effects of the latter drug. 



One important factor in this disease is to keep up the general system 

 by giving easily digested food of a mixed character and in concentrated 

 form, and administer wine or brandy in small quantities. If the heart 

 should give evidences of weakness, use stimulants, brandy, spirits of cam- 

 phor, or digitalis. 



In chronic bronchial catarrh where a permanent cure is not to be ex- 

 pected, we can alleviate the sufferings of the animal by inhalations of 

 tincture of benzoin or balsam of Peru, one teaspoonful to a cup of boiling 

 water, or by means of the vaporizer; inhalations of medicated vapors are 

 very useful, and especially the vapors of turpentine, where there is a 

 great accumulation of mucus and a foetid breath. Inhalations of the 

 vapors of tar and creosote are also useful. The action of tar is a little 

 irregular and occasionally destroys the appetite. Ichthyol and thiol are 

 given in doses of 0.2 to 0.5 gramme several times daily. Narcotics should 

 be administered only when the cough is very severe.
