What is the treatment ? 



In simple cases, absorbing ointments, mild blisters, etc. 



If suppuration is taking place, hot poultices, blisters; open 

 the abscess when ready, taking the greatest of care. 



Internally, cooling drinks, absorbents, internal antiseptics, etc., 

 according to indications. 



PHAKYNGITIS. 



Define pharyngitis. 



It is an iniiammation of the mucous membrane lining the 

 pharynx, and characterized by more or less difficulty in deglutition. 



Give the aetiology 



It is usually associated with, or secondary to, laryngitis, it being 

 as a rule an extension of the inflammation. 



It may be caused by mechanical, chemical, or thermic irrita- 

 tion, and in some cases it may be of a contagious nature. 



What are the symptoms ? 



The first symptom noticed, as a rule, is that the animal refuses 

 to eat; he may make attempts, but is unable to swallow, as there 

 is a difficulty in deglutition. 



It is a febrile disease, but the temperature is not very high, 

 being about 101° or 103° F.; there is no cough present, unless 

 laryngitis is associated with it, or food, etc., irritates the parts. 



One marked symptom is the return of liquids through the nos- 

 trils. If you give the animal a pail filled with water, he takes a few 

 swallows, stops, and the water is regurgitated through the nostrils. 



There is an inability to swallow, and often solid material and 

 mucus or pus are returned through the nostrils. 



How is the diagnosis made ? 



By the slight fever, the inahility to swallow (especially liquids); 

 by the absence of much pain on pressure over that region. 



Give the differential diagnosis between pharyngitis and 

 laryngitis. 



In pharyngitis the temperature is lower than in laryngitis; 

 pain is slight or wanting in pharyngitis, whereas it is very pro- 

 nounced on pressure in laryngitis. In pharyngitis there is difficulty 

 in swallowing liquids, while in laryngitis liquids are more easily 

 taken.
