30 DISEASES OF THE HORSE.

Bronchocele. — Pronounced ^^bronch-sea?,", is an 

 enlargement of the thyroid gland, and is situated on 

 and in front of the windpipe, about three inches from 

 the lower jaw. In horses it is only an eye-sore or ble- 

 mish. 



Causes. — In the horse it is unknown, nor is it deter- 

 mined what office or use the thyroid gland performs in 

 man or animals. 



Treatment. — Apply with friction by the hand once a 

 week, biniodide of mercury, one drachm; hog's lard, one 

 ounce. Mix, and make an ointment. Rub in a piece 

 about the size of a hickory nut over and around the en- 

 largement. 



Broken Knees. — When a horse stumbles and falls 

 upon his knees, and takes the hair and some of the skin 

 off, this is called broken knees. 



Treatment. — Wash and cleanse the parts from sand 

 and dirt, and if the skin is ragged and torn, clip off with 

 a good pair of scissors. After this is done, ascertain if 

 there is any discharge from the sore of an oily substance, 

 and if so get a smooth piece of iron, immerse it for ten 

 minutes in boiling water, and apply it to the edges of the 

 wound, so as to cause the parts to swell, and prevent 

 the escape of the joint oil; for if this be allowed to es- 

 cape, the ends of the bones will come against one an- 

 other. Irritation and inflammation will be set up, and 

 either destroy the life of the horse, or make an anchy- 

 losed or stiff joint. This is an important point to be ob- 

 served, and that very early in all cases of broken knees
