except where all other means have failed, for it is liable 

 to be followed by evil results. 



CAPPED HOCK 



Is of two kinds — synovial and serous. The synovial ap- 

 pears as a tense, fluctuating swelling, on both sides of the 

 point of the hock. It causes lameness and sometimes 

 abscesses from caries of the bone. The serous (a watery 

 abscess) is caused by pressure or violence, especially kick- 

 ing. It is unsightly when large. It sometimes causes 

 lameness.

Remedy — Hot fomentations; then stimulate by can- 

 tharides liniment or mercuric iodide ointment; soft soap 

 rubbed in daily a Equable pressure sometimes applied by 

 truss. Evacuate serous abscess; inject cavity with iodine 

 or astringents. In bursal form of capped hock use shoe 

 raised at heel. 



Treat Capped Knee and Capped Elbow the same as 

 Capped Hock. 



SANDCRACK 



Consists of a fissure of greater or less extent in any part 

 of the foot, but usually in the inner quarters of the fore 

 and the toes of the hind feet. The crack opens and closes 

 at every step, causing great pain and sometimes bleeding. 

 Some horses seem to be predisposed to the disorder, but 

 the cause is usually bad shoeing. Sandcrack never unites. 

 A new crust must be cultivated.
