228 DISEASES OF THE HORSE'S FOOT 
devised by Colonel Nunn may be used in its stead (see 
Fig. 108). 
The toe-piece is screwed into the toe of the shoe when 
the horse is about to be exercised, and forms a powerful 
point of leverage with which to stretch the contracted 
tendon, and the shoe, being thin at the heels, admits of 
this. The advantage of this form of toe-piece over the

denote that the cartilage itself is diseased, or that the 
wound is not able to be sufficiently drained from the sole, 
then we know that we have on our hands a case of quittor. 
The treatment necessary in such a case will be found 
described in Chapter X. 
When the Complication of Purulent Arthritis has arisen, 
the surgeon has to admit to himself, reluctantly no doubt, 
that the case is often beyond hope of aid from him. 
Nothing can be done save to order continuous antiseptic 
baths and antiseptic irrigation of the wounds with a quittor 
syringe, and to attend to the general health and condition 
of the patient. At the best it is but a sorry look-out both 
for the veterinary attendant and the owner of the animal. 
Even with resolution incurable lameness results, and the
