7C) The Ailments of Horses. 



the effects of concussion, and is said to be 

 commonest in racehorses. 



A blow is capable of bringing it on. 



It is an inflammation of the membrane 

 covering the bone — cannon-bone. 



Heat, pain, lameness, and swelling are 

 the chief symptoms. 



Treatment. — Rest, and cooling lotion 

 to the inflamed part. If an abscess forms 

 the matter must be allowed to escape. 

 This is done by scarifying the part, but 

 skill is necessary for this purpose, there- 

 fore it is advisable to consult a veterinary 

 surgeon. 



Sitfast. — By a " sitfast " we mean an 

 indolent sore upon the back. There is a 

 seat surrounded by a zone of dead tissue, 

 or a tissue at any rate that impedes the 

 healing process. 



Excision of the dead tissue brings good 

 results, but a blister can be applied 

 around the sore. It is necessary to keep 

 the animal off its work if a cure has to be 

 effected. 



Side-bone. — At the back of the coffin- 

 bone two flexible pieces of cartilage are 

 attached. These vield an elastic feel 

 when the thumb is pressed against the 

 upper and back j^art of the hoof, provided 

 that they are healthy, but don't respond 

 to this pressure if diseased. 



Now, in side-bone we find that they 

 have gradually become hard, and assumed 

 a bony-like character. It is this which 

 constitutes side-bone. Heavy horses are 

 those usually affected, though in these 

 the disease is the least objectionable.
