204 CHAPTER 22. 



of brevity, we may call preventible causes, probably aggravated at the 

 time by sudden atmospheric changes. With young horses first brought 

 into stables catarrh is of very frequent occurrence. It is also occasion- 

 ally found as a consequence of or accompanying laryngitis or sore throat, 

 because the inflammation set up in that disease very readily extends to 

 the similar continuous membrane of the nostrils. 



Catarrh is commonly said to be epizootic ; but this result need not be 

 feared, except where predisposing causes, such as neglect and bad ven- 

 tilation, render the animals susceptible of the disease. It is most fre- 

 quent, as we might expect, during cold damp weather. 



414. Symptoms. 



The premonitory symptoms are loss of appetite, dulness of the eye, 

 staring of the coat, a tendency to sweat upon slight exertion, and a little 

 watery discharge from the nostrils. These premonitory symptoms are 

 usually followed by slight feverishness, slightly quickened pulse and pro- 

 bably somewhat hurried breathing, and a hot mouth. The bowels are 

 usually constipated. In most cases the throat is more or less sore, and 

 cough may be present. 



In the early stage of the feverish symptoms the natural secretions of 

 the part are, as is usual in inflammatory attacks, temporarily arrested; 

 but in the second or moist stage there is an increased discharge from the 

 nostrils. 



If the disease runs on, the glands under the jaw become inflamed and 

 swollen from sympathy with the inflammation existing in their neigh- 

 bourhood. If the throat becomes positively sore, Laryngitis may be said 

 to have supervened. 



415. Treatment. 



The treatment required is simply removal at once to a cool loose box, 

 with abundance of fresh air, extra warm clothing, flannel bandages to 

 the legs, carrots, or green food, warm mashes, and laxative diet instead 

 of corn. With proper care no case of incipient catarrh ought ever to 

 be allowed to develop itself into any serious mischief. A very few days 

 will in general see the patient restored to health. 



Catarrh, if neglected, readily runs into laryngitis, bronchitis, pneu- 

 monia, or other disease of the respiratory organs. In some few cases it 

 becomes chronic, and is then known as nasal gleet. Good nursing is 

 imperative. The reader is referred to Chapter 15 on Nursing. 



LARYNGITIS AND SORE THROAT. 



416. Seat and nature of Laryngitis and Sore throat. 



The seat of Laryngitis is in the membrane covering the upper part of 

 the Larynx or box of the windpipe. When the pharynx or back part of 

 tbe swallow is affected, the disease is termed Sore throat. Both affec-
