GENERAL REMARKS 



The DiSEASiis of cone arc not commonly attended by any constitutional 

 disturbance, and neither require an examination of general symptoms, nor 

 the adoption of any but local treatment, beyond that attention to the health 

 which is ahvays necessary. They may all be included under the heads of, 

 — 1st. Exostosis, or increased growth of bone. 2nd. Caries, or ulceration, 

 3rd. Anchylosis, or unnatural union of two bones, in consequence of 

 exostosis, or caries, or both. Jth. Fractures, or disunion by external force. 

 Malignant diseases of the bone also occur very rarely in the horse, so that 

 it -will be scarcely necessary to occupy any space with their description, 

 especially as they are perfectlj- incurable. 



Exostosis is the result of increased action in the nutrition of the part, 

 and is much more prevalent in 3-oung horses than in old. It may be 

 recognized by a hard swelling of the part, which in recent cases is painful 

 on pressure ; but sometimes its site cannot be reached with the finger, and 

 the disease can then only bo detected by its efTccts. A blow upon any of 

 the bones when unprotected by anything but .skin will produce inllammation 

 followed by exostosis; but the most ordinary cause is the over-stimulus of 

 hard work. Heavy horses are more prone to exostosis than light ones, 

 partly from the weight of their bodies and their high lumbering action
