196 VETERINARY SURGICAL THERAPEUTICS. 
The tissue of new formation which repairs solutions of continuity and 
losses of substance is at first, we have said, exclusively formed of embryonal 
elements and blood vessels ; as its organization becomes more complete it 
sustains a retraction which gradually increases: the 
hair, follicles, sudoriferous and sebaceous glands are 
not reconstructed. 
Cicatrices whose development is complete are glab- 
rous, dry, ordinarily indolent, smooth or slightly rough, 
marked with ridges and fissures little developed, some- 
times with bands and grooves running in various di- 
rections. With some there remains, even for a long 
time, a great sensibility. When they are situated in 
regions where there are frequent motions (those upon 
which the harness is) or on the tissues of the foot, 
they interfere with work and even prevent it, or impose 
amore or less active interference, such as the removal 
of the innodular part, the thinning of the new hoof, 
or neurotomy. When the pain seems to be due to 
the adherence of the cicatrix to the tissues underneath, 
this must be divided subcutaneously and a sound ad- 
herence prevented by passive movements applied 
on the cicatricial plate. This operation is, however, 
seldom successful. 
Projecting cicatrices, otd and fibrous—the cicat 
Hee Heeas ricial cheloids——generally do.not yield to the means for 
Cheloid of the recent wounds which we have spoken of. Formed by 
Left Foreleg. dense connective fasciculi, elastic fibers, blood ves- 
sels and an epidermic covering, they are at tinres some- 
what regular, at others mammillated, mtultilobular, always: fibrous, whitish, 
glabrous, hard under the scalpel, or are covered with stratified epi- 
dermic layers or horny growths. Among cattle, we have seen some of 
those horny plates in various regions, and among horses, on the lower 
parts of the legs. According to their dimensions and the length of time 
they have existed, they are treated by cauterization or excision. 
Recent sessile cheloids may disappear by long and continued methodic 
pressure or by repeated scarifications and mercurial applications. When 
these fail, ablation is the only treatment offering any chance of success. 
This is also the best way to get rid of enormous projecting cheloids, more 
or less pedanculated. Among animals, relapses are rare outside cases of 
cicatrices resulting from the extirpation of tumors. Primitive neoplasms 
of innodular plates are also exceptional. 
Some very extensive wounds, and all those accompanied with loss of
