DISEASES OF HORSES. 151 



ringbone when once the cartilage has been converted 

 into bone. 



• Treatment. — Apply a sweating liniment in the first 

 stages. If driven let the horse wear a knee-boot. 

 Rest is essential until the soreness is worn off. Ap- 

 ply a liniment compound of the following: 



Tr. Capsicum 4 oz. 



Chloroform 4 oz. 



Olive-oil 4 oz. 



Mix and apply. Repeat as often as you think neces- 

 sary. 



CURB. 



A curb is an enlargement which makes its appear- 

 ance on the hind legs, about two inches below the hock. 

 It is sometimes occasioned by a blow, but the most 

 frequent cause is a strain of the sheath through which 

 the flexor tendons pass. If seen in its early stage it 

 would in all probability yield to rest and cold water 

 and bandages; but if neglected until effusion takes 

 place and thickening intervenes and the horse becomes 

 lame, then a different course of treatment must take 

 place. Our usual remedy is a paste made of the fol- 

 lowing, to be applied morning and evening: 



Citron ointment 3 oz. 



Pulv. cantharides i oz. 



Add one ounce of olive-oil to make a paste. Cleanse 

 well before an application is made. Apply only over 

 parts affected and heat well in. Two or three applica- 

 tions are all that are necessary. To absorb after the 

 sweating, hand-rub well and often. The whole matter 

 will take up about two weeks if properly attended to.
