Spts. camphorse et. tr. opii, pars equale, or camphorated 

 liniment two parts to aqua ammon. one part. Ammoniacal 

 liniment alone is good ; and wet cloths applied around the 

 .splint and covered with dr}^ ones Avill in many cases be suf- 

 ficient to allay and keep down irritation ; but rest is very 

 essential, and should be given if the case is to be treated 

 properly. "When a splint becomes fully developed, that is, 

 attains its maximum size, etc., irritation ceases, and with it 

 lameness. 



SORE SHINS. 



The condition known as sore, or bucked shins, consists of 

 an inflammation of the periosteum covering the metacarpal 

 bones, and consequently it is a form of periostitis. It is 

 astonishing from how many forms of periostitis horses suffer. 

 It is analogous to splint, but differs, inasmuch as the inflam- 

 mation of splint is circumscribed, while in sore shins it is 

 more or less diffused. The inflammation is not always con- 

 fined to the metacarpal bones, in some cases the knee, and 

 occasionally even the radius, becoming affected. 



Pathology. — The exciting cause having operated, inflam- 

 mation is set up in the periosteum, as a result of which an 

 exudate is thrown out, usually taking place between the 

 periosteum and the bone, but sometimes it takes place 

 external to the periosteum. The enveloping membrane of 

 the bone becomes more or less thickened, and in some cases 

 the inflammation is so severe as to terminate in necrosis, 

 especially in neglected cases, and where the exciting cause 

 has been kept up. Sore shins is of more frequent occur- 

 rence among racers than any other class of horses, and 

 although occasionally met with among horses used for 

 ordinary purposes, it may be said to be almost confined 

 to those of fast work, as racehorses, hunters, etc., and then 

 is only rarely met with in horses of mature years, being chiefly
