tlie usual form is that of aii encysted tumor, or a fluid contained 

 within a CN'st of fleshy walls, which do not su[)purate. 



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

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

 preventing the animal from proper]}^ 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 sharjj 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 cue 

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

 day, a little tincture of iodine, to kill the walls of the cyst, so that 

 it will not fill again. (See Medicines ) A knife is only w^anted 

 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 b}' an}^ other horse. 



Treatment. Apph' 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 necessar}?', an ointment composed of one drachm of 

 iodide of morcurv , 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 tlie upper teeth be ulcerated to any extent, 

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

 on which the diseased teeth are situated, wdiicli has been re-
