ELEMENTS OF HIPPOLOGY. 57 



animal should be killed and burned and all his equipment and 

 surroundings burned or thoroughly disinfected. If, however, on 

 the second test he does not respond, a third test should be made 

 at the end of another month, which may safely be regarded 

 as final. 



Any horse presenting a discharge at the nostril should be at 

 once isolated, and his stall and all his equipment thoroughly 

 disinfected. 



Nasal gleet is a chronic diseased condition of the nasal 

 membranes and of the linings of the facial sinuses. It is the 

 result of neglected colds (bad stable management), or ulcerated 

 teeth, and is a stubborn disease to cure. It is marked by a dis- 

 charge from the nostrils, one or both, offensive odor, and fre- 

 quently by no other outward symptom. Nasal gleet and glan- 

 ders are frequently mistaken, one for the other. 



Influenza is a highly infectious disease, usually of brief 

 duration. True influenza usually spreads in waves of contagion 

 over large areas. It is easily spread and difficult of treatment. 

 The patient is stupefied, hangs its head, is not easily roused; the 

 eyes become inflamed and tears flow profusely. It is frequently 

 followed by disabling complications. 



Catarrh is inflammation of a mucous membrane. It is 

 called by various names, depending on its location. 



Cold in the head is an inflammation of the mucous mem- 

 brane of the nasal passages and neighboring regions. It is man- 

 ifested by dullness, fever, a watery discharge from the nose, and 

 sometimes by an inflamed condition of the eyes. The patient 

 should be exercised very little, placed in a loose stall, well ven- 

 tilated, but free from drafts. Like the human disease of the same 

 name, the watery discharge, as the disease progresses, becomes 

 thicker and of a whitish color. Colds in the head ought not to be 

 neglected, nor should animals so affected be put to severe work 

 until cured.
