322 SEAT AND NATURE OF FARCY. 



constitutions — we know that the valves, as well as the tunics, do 

 however inflame and ulcerate or become absorbed ; and that in 

 consequence, the farcy pustules run one into each other, and by 

 such communication lose their characteristic shape, lengthening 

 into fistulous abscesses, well known to farriers under the denomi- 

 nation of " farcy pipes," or spreading into abscesses of large and 

 irregular shape, burrowing deep in the connecting cellular tissue. 



The Skin — the cutis vera — undergoes changes very analogous 

 to the thickening and induration of the farcy-bud. In the course 

 of time it becomes enormously augmented in substance, remark- 

 ably white, and unusually tough and hard, cutting like so much 

 white leather rather than skin, especially in the immediate vicinity 

 of the buds ; several of the more superficial of which, some that 

 have become pustules, will be found embedded in its thickened 

 substance. We, however, no sooner cut through the indurated 

 cartilaginous-like cutis than we expose chains of farcy-buds and 

 pustules, immediately underneath it, invested by cellular tissue 

 full of infiltration of a jelly-like citron-coloured fluid, beyond 

 which bed of eff'usion we appear suddenly to lose all vestiges of 

 disease. To this, however, there are exceptions. In inveterate 

 farcy the infiltration will sometimes be observed extending deep 

 between the muscles, and every now and then abscesses, depots of 

 matter, of considerable volume, will be discovered buried among 

 the fleshy structures. Nor do the bones, no more than the mus- 

 cles, escape the ravages of farcy and glanders : we know how the 

 turbinated and ethmoid and nasal and maxillary bones have suffered 

 in malignant cases of the former disease ; and we are assured by 

 Dupuy and others, that many of the bones of the limbs and body 

 have proved extensively diseased in horses that have for a length 

 of time been afflicted with farcy.
