294 VETERINARY SURGICAL THERAPEUTICS, 
along the tendons and collects in a large cul-de-sac; the tracts must be 
enlarged, the pus given free escape, painful pressures relieved and the 
necrosed tendinous part freely exposed or removed. Incisions should’ be 
made parallel to the axis of the leg, avoiding the blood vessels and nerves ; 
the fistule should be curetted and the purulent pouches disinfected with 
antiseptic washes. Should profuse hemorrhage occur, plugging with iodo- 
formed dressing should be applied. 
The therapeutic agents recommended have varied with the various epochs 
of their introduction. Actual cautery to a white heat, applied on the mor- 
tified tendinous part, has given and yet gives good results: it modifies 
the putrid into an aseptic eschar, and the surrounding tendinous tissue 
may remain free from infection and recovery may take place. But this 
process is not sufficiently sure; the cauterization is either too much or 
not enough; and often the necrosis keeps on, even after an extensive 
slough has taken place. Among the caustics used in the first two-thirds 
of this century, corrosive sublimate, in powder or in pencil, introduced 
into the fistulz, arsenious acid, nitrate of silver, and. sulphate of copper 
have been recommended. 
A large number of liquid, caustic or disinfecting preparations have 
been recommended for tendinous quittor. Two among these —Villate 
solution and tincture of iodine—have proved themselves especially ad- 
vantageous, and they are still extensively used. When injected several 
times a day into the bottom of the fistule, at the same time carefully 
preventing contraction of these by the introduction of tents or plugs, they 
have often brought on recoveries. With baths of sulphate of copper, 4 
to 6 in 100, repeated twice a day, Rey and many others have obtained 
excellent results. The great objection to very strong solutions is that 
they have too powerful an escharotic effect on the skin of the soaked re- 
gions. Aureggio has advised the use of g/ycerine. Carried into the focus 
of the necrosis, it may, like the preceding agents, clean off the fistule, 
the undermined spaces, and the exfoliated part of the tendon. 
Antiseptic treatment is to-day preferred to hydrotherapeutics. Iodo- 
form, in powder or united with vaseline or glycerine, has proved itself very 
active. We have used it with great advantage. More or less concentrated 
solutions of corrosive sublimate are also precious agents. They are used 
in strength of 1 in 1000, 1 in soo, or 1 in 100 (water 100, glycerine 10, 
corrosive sublimate 1). At present tendinous necrosis is especially treated 
with antiseptic liquids. Free incision, drainage, antisepsis, is the formula. 
Often in the course of the disease, when synovitis complicates tenositis, 
abscesses have to be punctured, counter-openings are to be made and 
new drains applied. If the antiseptic irrigations are well done, little by 
little the suppurations will become less abundant, the pus will change
