the usual form is that of an encysted tumor, or a fluid contained 

 within a cyst of fleshy walls, which do not suppurate. 



Cause. The horse, when lying, rests the point of the elbow upon 

 the heels of his front shoe. It is a symptom of disease of the leg, 

 preventing the animal from properly flexing or bending the leg 

 proper upon its thigh or arm. Hence the elbow rests upon the 

 foot. 



Prevention. Remove whatever disease may be in the leg, and 

 place a pad of leather, or of coarse, heavy cloth, over the back 

 part of the foot. Pads are made by harness makers. 



Treatment. Make an incision with a sharp knife through the 

 skin, over the centre of the swelling, and carefully dissect the cyst 

 from its attachments. This can be done with the fingers and a 

 blunt piece of wood, flattened at its points like a butter knife, and 

 no sharper. If the operator be timid, and think he cannot cut 

 the cyst out, open it, and let out the matter, and inject, once per 

 day, St ]Utle tincture of iodine, to kill the walls of the cyst, so that 

 it will not fill again. (See Medicines.) A knife is only wanted 

 to cut the skin. After the tumor is taken out, treat the part as a 

 simple wound, by keeping it clean, and applying a solution of 

 zinc, or blue stone. 



Chapped Hock. — This is a soft swelling on the point of the 

 hock-joint. 



Causes. Kicking in the stable or in harness, lying upon stone- 

 paved stalls, and from being kicked by any other horse. 



Treatment. Apply cold water cloths to the part for a few days, 

 taking them off at night. After the heat and tenderness have 

 subsided, apply, with rubbing, once every fifth day, for three 

 times, if it be necessary, an ointment composed of one drachm of 

 iodide of mercury , and hog^s lard, one ounce. Mix. 



Carditis. — This is applied to disease of the heart. Heart 

 disease is also known as the Thumps. Incurable, (See Heart 

 Disease.) 



Caries. — This term means an ulceration of the bone. The most 

 frequent form of caries is seen on the lower jaw-bone ; the teeth 

 are next affected. If the upper teeth be ulcerated to any extent, 

 ? fetid (stinking) discharge will run from the nostril upon the side 

 gr which the diseased teeth are situated, which has been re*
