'J 2 THE PRACTICE OF VETERINARY MEDICINE. 



Snoring is symptomatic of some nasal obstruction, as 

 a polypus, etc. ; this sound also occurs as a symptom of 

 brain disease. 



Sneezing is indicative of an irritable condition of the 

 pituitary membrane. 



Grunting. — This sound is referable to the larynx, and 

 may or may not be connected with disease; it usually lie- 

 companies roaring, and is always to be regarded with sus- 

 picion. Any painful disease may cause an animal to grunt, 

 and some animals have an ugly habit of grunting without 

 the presence of disease. 



Cough may be defined to be a laryngeal sound, pro- 

 duced by the violent expulsion of air from the lungs. 



Suppressed cough is the sound emitted by the animal 

 when suffering from a disease in which the effort of cough-

 is easily detected by a slight pressure of the larynx, and is 

 usually of a hollow sound. 



Treatment. — Bad hay and oats, dusty food, etc., should be 

 carefully avoided, and the following very simple, but never- 

 theless very good remedy in some cases is worthy of a trial : 

 antimon. tart. 5i- twice a day for nine or ten days. Another 

 old and powerful remedy, which was highly thought of by 

 Professor Dick, is as follows : hydrarg. subchlor., digitalis, 

 camphorse, opii pulv. aa 5ss. ; to be given in a bolus every 

 other morning before feeding. 



Bronchocele. — Close to, and behind the larynx, is situated 

 the thyroid gland. This gland frequently becomes hyper- 

 trophied, constituting an affection known as bronchocele. It
