258 VETERINARY SURGICAL THERAPEUTICS. 
on the parts, the tumor begins to increase in size, to indurate and to as- 
sume a character of chronicity which renders recovery very difficult. All 
kinds of vesicating agents have been tried (blisters of cantharides and of 
mercurial preparations, etc.). The best- results have been obtained by 
repeated applications of preparations of 
moderate activity. In these seems to be 
the secret of success. Thus can be ex- 
plained the results obtained with the Weber 
preparation, which has shown itself most effi- 
cacious in numerous old voluminous capped 
hocks. Rest is not necessary; on the con- 
trary, work is advantageous during the treat- 
ment. 
Penetrating point firing has its patrons; 
we have used it with -success, but it is 
slow, not to be depended upon, and leaves 
scars. Puncture is insufficient.  Jodine 
injections have given recoveries to Leblanc, 
Cambron, Verrier, Liard, and many others. 
Leblanc’s case was the size of the fist, of long 
date, and had resisted many forms of treat- 
<=", ment. The animal was very nervous and 
== = had to be thrown to receive the injection 
Fig. 61.—Capped Hock. (1 per cent. tincture iodine, 2 per cent. of 
water). After fifteen days, the liquid col- 
lection having returned, a second injection was made. Recovery 
was complete. The mare treated by Cambron had a capped hock as big 
as a child’s head; puncture gave escape to one anda half liters of 
fluid. A first injection being followed only by improvement, asecond was 
made, and the tumor disappeared entirely. Verrier injected two volumin- 
ous capped hocks on the same horse; he saw the animal three months 
afterwards entirely recovered. A horse treated by Liard (obs. 6) was also 
cured by one injection: after three months the growth was reduced three- 
quarters of its size, and ultimately disappeared. Another horse (obs. 5), 
after the injection, rubbed its hock against the stall, the sac opened, sup- 
purated and filled with granulations; later the tumor subsided, but the 
point of the hock carried a cicatrix. 
Free incision made without asepsis exposes the lesion to severe compli- 
cations : at times it becomes a suppurative phlegmasia of long duration, or 
the growth indurates and considerably increases. Even when made an- 
tiseptically and completed with a wadded dressing, the operation does not 
seem to have given such brilliant results. Besides, it requires a long rest,
