CASES OF QUITTOR, &C. 
are nearly filled with granulations : apply nothing to them. The 
anterior wound and ulcer of coronet are granulating tardily — pus 
thin. Continue the lint, with weak solution of chloride of lime, to 
this wound. 
1 Oth. — The anterior wound and ulcer progressing slowly: the 
two posterior wounds are partially covered with a thin layer of 
horn secreted by lamina. 
1 Oth. — The two posterior chasms are well protected with horn, 
which offers considerable resistance to presure, save on the coro- 
nary surface, where the layer of horn is very thin and yielding : 
the ulcer of coronet and anterior wound progressing slowly. 
20th. — There is no more lameness than what may be attributed 
to the ossification of the cartilages : the wound and ulcer are much 
improved since last visit. 
2 4th. — The two posterior chasms of wall are now everywhere 
filled up to a level with the adjacent horn — the anterior wound is 
partially covered with horn, secreted by lamina — a space of an 
inch or more at the coronary surface remains uncovered with horn : 
ulcer has cicatrized. The proprietor has now determined that the 
mare shall go to light work, the foot being properly protected. 
May 1th. — Has worked regularly without the lameness increas- 
ing. The anterior division of wall is pretty much filled up below 
the coronary surface, but at the coronary surface no horn has been 
formed. 
January 10, 1848. — The mare has continued regularly at work. 
The two posterior fissures are growing out, leaving an even surface 
above : the anterior fissure remains in statu quo — the coronet at 
the seat of the ulcer feels hard — a thick layer of cuticle has extended 
an inch down the fissure. A plain shoe has been worn ever since 
June last, and no treatment was required after the 24th of April 
last. 
In this case various caustics had been employed, but their action 
did not prove to be beneficial. The healthy structures appear to have 
been more affected by them than the disease ; and as these agents 
are not entirely under the control of the practitioner, or exposed to 
his view, the false quarter which so frequently ensues upon the 
cure of quittor may, perhaps, in a majority of cases, be attributed 
to the potency of the remedies made use of. The knife, on the 
other hand, inflicts an injury which exposes the disease, and by 
admitting the atmosphere sets up a beneficial degree of inflamma- 
tion ; — the extent and nature of the disorder are laid bare, and the 
senses are enabled to instruct the judgment. A harder test upon 
any operation could scarcely have been selected than the present 
case, which had been in existence for a considerable period before 
I saw it, and was under my care four weeks before I adopted the
