IXFEUEXZA. 



ACUTE NASAL CATARRH. 



Acute nasal catarrh (simple cold in the head) is usually pro- 

 duced by cold caused by standing in a draft, and may be detected 

 by the discharge from the nostrils. It is usually accompanied 

 by a cough, loss of appetite, and elevation of tempsrature (fever) . 

 The discharge is at first of the consistency of water, but may in 

 severe cases become much thicker, and form dry crusts on the 

 edges of the nostrils. 



Treatment. — The mild form does not require treatment; it ends 

 rapidly in a cure. In severe cases, fumigation (steaming) with

 local treatment. Give bran mashes, and administer twice daily 

 1 teaspoonful of saltpater, or 1 tablespoonful of chloride of 

 ammonia until the animal has recovered. If the cough is fre-

 liniment should be applied to the throat: Ammonia 1 part, oil 

 of turpentine 1 part, olive oil 2 parts. Apply twice daily.

Usually an unfavorable termination of simple catarrh; or it

 nasal cavities, tumors, parasites, abscesses, etc., of the nasal cav-

Symptomfi. — The discharge is quite thick and becomes glued to 

 the sides of the nostrils; its color varies from a dirty to a yellow-
