18 THE NATURE AND TREATMENT OP 



thrown into the rectum. Should the symptoms become more 

 alarming, the services of a veterinary surgeon will be required, 

 to perform the operation of tracheotomy : which consists in 

 taking a circular piece of cartilage out of the trachea, and in- 

 serting therein a common tracheotomy tube. If the disease be 

 confined to the parts above the seat selected as the place of 

 operation, the animal may yet be saved. When the disease 

 passes into the chronic stage, we have a purulent discharge 

 from the nostrils. This discharge may be accelerated by giv- 

 ing a few doses of the following :

 chronic laryngitis ends in thickening, or altered structure, of 

 parts within and around the larynx ; should this be the case, 

 the patient must be put on a course of iodine ; twenty grains 

 per day of iodide of potassium may be given, in a small 

 quantity of water, and the region of the throat should be 

 anointed every night with the following ointment : — 



Powdered Iodide of Potassium, 2 drachms. 



Simple ointment, 2 ounces. Mix. 



BRONCHITIS. 



Bronchitis is a disease of the bronchial mucous membrane ; 

 in its early stage the term acute has been applied to it, this 

 having subsided it assumes a chronic type. It is very rare 

 that this is a primary affection, for it is generally preceded by 

 cough or catarrh, or else is an accompaniment of an abnor- 

 mal condition of contiguous tissues. Its existence may be 

 demonstrated very readily by applying the ear to the trachea 

 in the region of the point of the breast bone, the peculiar sound 

 differing from that in any other part of the trachea, having what 

 is termed a sibilantf or whistling sound. The treatment will
