DISEASES OP THE RESPIRATORY OKGANS. 307 



and a discharge from the nostrils, which, if profuse and coming 

 away freely, is to be regarded as a favorable sign. 



Treatment. — Secure an abundance of pure air; place the 

 patient in a comfortable, loose, box stall. Hand-rub and flannel- 

 bandage the limbs. Administer the medicine, if possible, in the 

 drinking water. If ho will not take it thus, it must be given in 

 a draught, using plenty of water to dilute the medicine. Inhala- 

 tions of steam and hot fomentations to the throat should be tried, 

 and if the distress is not quickly relieved, tracheotomy must be 

 resorted to. Where the case is not so urgent, the fomentation 

 and the use of the ammoniacal liniment to the throat will usually 

 suffice. Chlorate of potash should be dissolved in the drinking- 

 water, and twenty drops of the tincture of aconite, in conjunc- 

 tion with alcohol or aether, may be given in a drench; one ounce 

 of either may be given. The results of laryngitis are thickening 

 of the mucous membrane, ulceration of the rima glottidus, atro- 

 phy of the laryngeal muscles, and follicular growths upon the 

 laryngeal entrance. Thickening of the mucous membrane is best 

 treated by putting the animal on a course of potassium iodide; 

 three drachms should be given three times a day. Ulceration of 

 the rima glottidus is treated with a solution of the nitrate of 

 silver. It should be applied by a little piece of sponge fastened to 

 a rod. The follicular growths are removed by the application 

 of a solution of corrosive sublimate. To prevent atrophy of the 

 muscles, the chlorate of potash should be used, in two-drachm 

 doses. 



BRONCHITIS. 



Bronchitis may be defined as an inflammation of the mucous 

 membrane lining the bronchial tubes. It is sometimes called 

 Catarrhal Bronchitis. 



Causes. — Bronchitis is due to exposure to cold. It frequently 

 arises during voyage at sea and by improper administration of 

 medicine, as through the nostrils, IMechanical bronchitis may 

 be produced by food gaining access to the trachea.
