90 DISEASES OF THE FEET, ETC. 



1 2th. Thorough-Pin. Is a large windgall on the hock, 

 between the cord and the bone. It is not in popular esti- 

 timation an unsoundness, but is regarded 

 as only an eyesore, and seldom has any bad 

 effect, such as laming or causing any stiff- 

 ness ', therefore I would not attempt to re- 

 move it, as it very often disappears when a 

 horse gets regular work and attendance. 



1 3th. Stringhalt. A sudden jerking up 

 THOROUGH-PIN. o f one or Dot ri hind legs. It is supposed to 

 be some obscure disease of the sciatic nerve. I know no 

 cure for it ; and although a horse will work on for years 

 with it, still, it is decided unsoundness, and shows more 

 in winter than summer.
