Splint is caused by concussion and hereditary predispo- 

 sition, especially that arising from shape and form of leg. 

 The effects of concussion may be due to the immature 

 age of the bone, shape of leg, method of shoeing, or 

 overwork or speed when young.

Remedy. — In slight cases stop fast work. Half dose 

 physic. Foment and then blister. In severe cases peri- 

 osteotomy. Pyro-puncture preferable to firing, as it does 

 not blemish. Mercuric iodide ointment usually reduces 

 deposit. 



STRINGHALT (CHOREA), 



Is a spasmodic movement of the muscles of the limbs, 

 usually the hind. 



Incurable. Eemove any spavin or other adverse condi- 

 tion. Temporary benefit results from a laxative, a course 

 of bromides, and moderate work. • Stretching and section 

 of the tibial nerves are of no avail. 



Other muscles are subject to spasmodic action, especi- 

 ally those of the spine,
