 knowledge of the diseases of the horse, to distinguish

 And in many cases, this is all that is required to set him 

 right afterwards; although it may be necessary some-

 what and where the difficulty is. 



The causes are various that bring on these difficulties.

 which settles across the kidneys — causing inflammation 

 there, while the water will look quite red. When he

 It is sometimes brought on by other disorders that have
