706 OPERATIONS ON THE FOOT. 



pression. We do not by it attempt to loosen the slough, which 

 it is advantageous to have detaching loose itself vs^hen it holds 

 only by its base. If the abscess, once formed, is slow to ulcerate, 

 making a point of cauterization is a good way to stimulate the 

 escape of the matter of the slough. This mode of opening pro- 

 duces in the part an increase of vital action and forms a sore of 

 benign character, which falls off by the effect of the suppuration 

 formed underneath, and which is nearly always followed by a 

 comj^aratively speedy recovery. To obtain this radical cure, it 

 remains to continue the use of the ordinary means to facilitate 

 suppuration and bring on resolution. If the wound is pal^ and 

 covered at the bottom with large granulations, it must be dressed 

 first with basilicon ointment and afterward with alcoholic liquids, 

 as spirits of camphor, tincture of aloes, or simply an aromatic in- 

 fusion; at times, baths of sulphate of iron, with a little siilphate 

 of copper, are indicated ; or, when the wound has become red, the 

 granulations vascular and of healthy character, a simple dressing 

 of cegyptiacum ointment, diluted in vinegar, is enough. If proud 

 flesh develops itself, it must be cut off. It is important to have 

 the wound covered with a protecting dressing, which must be re- 

 newed daily if the suppuration is very abundant, or it may some- 

 times be left on for two days. 



B. Tendinous Quittok. — Synonym: Hornwurne (Germ.) — 

 It is the nervous quittor of hippiatres, and the analogue of the 

 felon of man. It is again a furuncle, different from the preceding, 

 only because instead of being limited to the skin and subcutane- 

 ous cellular tissue, there is caries of a portion of the tendons 

 (especially the flexors), or of the ligaments of the region, and also, 

 at times, necrosis of the bone with synovitis and arthritis. By 

 extension, though we think, improperly, the name has also been 

 given to the felon of the region of the cannon, while the applica- 

 tion ought to be confined to that of the digital region, situated in 

 the fold of the fetlock. 



The quittor may be suj)erficial or deep-seated when it affects 

 only the subcutaneous cellular tissue, uniting the skin to the ten- 

 dons, or whei'e the inflammation extends to the phalangeal sheath, 

 and the pus accumulates into it. Differing from cutaneous quit- 

 tor, this form, generally less common, is more frequently seen in 

 the anterior than the posterior extremities. It may also be seen 

 in cattle.
