62 THEORY AND PRACTICE 



nux vomica every hour night and day and a dram of alcohol 

 and 20 grains of quinine at the same time. 



Alcohol promotes diuresis sufficiently in this stage. It is a 

 good plan to add a little gentian to keep the stomach in order. 

 Give the animal anything that he will eat. 



Counter-irritation I am a firm believer in. For this use 

 ammoniacal liniment or mustard. 



As to hygiene keep the patient warmly clothed and the stable 

 at the right temperature. 



In painful persistent bronchial cough give fl. ex. glycyrrhiza, 

 ammonium chloride, strychnine, strophanthus or digitalis, and an 

 anodine such as heroin (an alkaloid) of which give a grain 

 every 4 hours. Make up a mixture on this basis. 



In prescribing you must know the physiological action of 

 drugs. 



As regards cats and dogs, they can be dosed according to 

 the breed, size and age of the animal. 



Cattle are more subject to fatal bronchitis than horses. 



Prognosis. — Bronchiolitis is serious. In acute bronchitis 

 90% recover and the other 10% includes bronchiolitis and sup- 

 purative bronchitis. 50% of bronchiolitic cases recover and 

 10% of suppurative bronchitis. 



Chronic Bronchitis does not exist very often in horses. It 

 has a peculiar morbid anatomy — a chronic dilatation of the 

 bronchioles, and a chronic irritation of the mucous membranes. 

 This in cattle is so marked, and the exudate is so plastic, that 

 fibrinous tumors forms in the large bronchi. This never occurs 

 in horses, but is found in people and in cattle and predisposes 

 the animal to tuberculosis, at least this is the general opinion. 



Such an animal is ahvays unthrifty and has a distressing 

 bronchial cough. 



Treatment. — There is not very much that can be done. Treat 

 on general principles. Give animal a grass diet. Give a heart 

 stimulant along with 



1. Iodide of Potash. 



2. Strychnine. 



3. Muriate of ammonia. 



4. Heroin.
