DISEASES OF DOMESTIC ANIMALS. 17 



(3.) Discharge has not a fetid smell. 



(4.) Discharge is yellow in color. 



(5.) Ulceration of septem nasi. 



(6.) Induration of sub-maxillary lymphatic glands. 



(7.) Temperature is considerably elevated. 



(1.) Generally comes from both. 



(2.) Does not adhere around the nostril. 



(3.) It has a fetid smell if of long standing or from a carious tooth. 



(4 ) Generally of a greenish cast. 



(5.) Septum nasi, not ulcerated. 



(6 ) Sub-maxillary glands are not injurated unless from a carious tooth* 



(7.) Temperature not much elevated. 



Treatment is somewhat tedious. Keep the animal well fed, wash the 

 nostrils once or twice a day, give plenty of pure air and some exercise, 

 use sulphate of iron, one, two or three drachms once or twice a day, 

 iodide of potassium, sulphate of copper, or balsam of copaiba. The best 

 preparation of iron is iodide of iron. In some cases counter irritation is 

 of use. Use biniodide of mercury. I have but little faith in injections 

 into the nostrils. As a general thing no purgative is required. It may 

 be necessary to trephine and allow the matter to pass out. Keep the 

 opening well opened, inject carbolic acid, sulphate of copper, etc. If it is 

 from a carious tooth, remove it. Sulphate of copper two drachms, can- 

 tharides five grains, made into a ball and given once or twice a day. or 

 sulphate of iron one drachm, arsenic three to live grains, strychnine two 

 grains, or substitute nux vomica for the strychnine. 



Bronchocell is enlargement of thyroid glands. ; it may vary from the 

 size of a pigeon's egg to the size of a man's hand. It is hypertrophy of 

 the thyroid glands. It is easily detected, and does not often interfere 

 with the animal in any way. 



Treatment. — Iodine and iodide of potassium one part to four or six of 

 lard; or you may dissect them out, but be careful, as the carotid artery 

 is very near ; but if you do cut it you can ligature it. It may be neces- 

 sary sometimes to use biniodide of mercury, or if cysts are formed you 

 may puncture them. 



Croup is that form of inflammation of the larynx where the exudate 

 becomes converted into false membranes ; it is a rare disease generally 

 seen in young animals. 



Causes. — Exposure to cold ; it occurs in animals confined to low, damp 

 pastures. 



Symptoms. — Extn mely difficult breathing, accompanied with a peculiar 

 crowing sound. 



Treatment. — Chlorate of potash, counter irritation, and it may be neces- 

 sary to perform tracheotomy. 



Abcesses of the turbinated bones. 



Treatment is to trephine, and let the matter escape. 



Tumours, or nasal polypi, are usually of a fibrous character ; there is 

 generally a small neck, which is attached to the mucous membrane ; they 

 may extend almost down into the nasal opening. It is not so common in 

 horses as in man. 



Causes — They may come from some change in the system. It is a 

 tumour, which does not grow again if it is removed. 



Treatment. — If it is small it is better to leave it alone, but if it inter- 

 feres with respiration it may be necessary to remove it, just with a pair 

 of forceps if it is near the nasal opening. It is sometimes formed back in 

 the pharynx, which is more serious than nasal polypi ; it may not do 

 much injury, and it may intei-fere with the larynx.
