 beneficial. 



If secretion is defective and cough hard and dry chloride of 

 ammonium, carbonates or bicarbonates of soda, potash or ammon- 

 ium or borax, in solution or in gaseous form, may be given, the 

 various bitters being at the same time drawn upon as tonics. If 

 secretion is excessive, with a loose gurgling cough, astringents are 

 indicated like ferric sulphate or chloride, (^ dr.), or they may 

 be applied as spray : alum or iron alum five grains to the ounce, 

 zinc .sulphate or sulphocarbolate two grains to the ounce, .silver 

 nitrate one-half grain to the ounce. These may be introduced 

 through the nose with the head elevated, or in small genera 

 through the fauces. Tar, oil of tupentine, creosote, carbolic acid 

 or eucalyptol may be inhaled from hot water.

 perspiration only. The disease, however, recognizes the same 

 causes as in the horse, though these are manifestly less injurious.

 In more acute cases the breathing is loud and wheezing, the 

 cough, soft and rattling, is followed by a free discharge of mucous 

 from the mouth, the nostrils and eyes are red, the muzzle dry,

 through the nose. If the larynx is chiefly involved the loud
