DISEASES OF THE RESPIRATORY SYSTEM. 125 



How is this disease diagnosed ? 



The diagnosis is easy, the symptoms being usually well marked. 



The discharge from the nose, the absence of symptoms of 

 other diseases, and the elevation of temperature two or three 

 degrees. 



What is the prognosis ? 



It is favorable if seen early and the animal is otherwise in good 

 health. Some eases, and especially neglected ones, often become 

 chronic or complications may arise — eye, mouth, throat, sinuses, 

 etc., may become involved; these cases last longer. 



What is the treatment ? 



Both local and systemic. 



In the milder cases, simple nursing may be all that is necessary. 



Keep the body warm by the use of blankets and bandages. 

 Put the animal in a box-stall where there is good, pure air, but 

 free from drafts. 



This trouble is often cut short by the use of quinine or opium 

 with camphor. Steaming is also used; bran put in a pail, with hot 

 water poured on, can be placed in a feed-bag and the animal al- 

 lowed to inhale the steam, which is often very soothing. It is well 

 not to confine the animal's head too completely but to allow a cer- 

 tain amount of air to be taken with the steam. A steam-producer 

 is now in common use by veterinarians, the advantage being that 

 disinfection can be accomplished at the same time. 



If there is much fever, potassium nitrate and tartar emetic 

 can be given in the drinking-water. 



Injections to unload the rectum are often beneficial. 



The diet should consist of bland food, easily digestible, which 

 is far better than forcing too highly nitrogenous food. 



CHKONIC NASAL CATAEKH. 



What are the synonyms? 



Nasal gleet, ozena, chronic rhinitis, fetid nasal catarrh. 



What is chronic nasal catarrh ? 



The word catarrh cannot properly be used, but it is held in 

 many text-books. 



It is a chronic inflammation of the mucous membrane lining 

 the nasal passages, accompanied by more or less structural alter- 

 ation and an increased discharge.
