SEAT AND NATURE OF FARCY. 
123 
COLEMAN pronounced farcy to consist in “ an inflammation and 
suppuration of the lymphatic vessels,” and added, that the disease 
had a predilection for the superficial to the exclusion of the deep- 
seated order of those vessels, the same as other diseases of the 
body had their peculiar seats. He considered farcy-buds to arise 
from effusions of adhesive matter into the canal of the lymphatic, 
distending the vessel in the intervals between its valves, which 
latter he regarded as insusceptible of the farcinous irritation ; 
“ for if,” said he, “ a diseased lymphatic vessel be examined, 
perfectly sound partitions of membrane will be found between the 
buds, which cannot be any thing else but the valves .” 
Leblanc, however, with whose researches and opinions we 
have had reason, when on the subject of the pathology of glanders, 
to be well pleased, regards the farcy-bud as the result of the coa- 
gulation of the lymphatic fluid or lymph, accumulated within it, 
in consequence of the obstruction in its incrassated condition the 
fluid (lymph) receives from the valves, to which accumulations is 
owing the well-known plumpness and rounded shape of farcy-buds. 
Still, Leblanc admits that the vessels themselves are “almost 
always” in a state of disease: he has found their coats thickened 
and opaque, their lining membrane frequently exhibiting red spots, 
ragged, adherent to the contained portions of coagulated lymph, 
and in places softened without any ulceration, or e!se altogether 
in a softened condition. This softening change in time pervades 
the other (thickened) tunics of the vessel, and even affects the 
contained clots of lymph, ending, at length, in points of ulceration, 
opposite to which the surrounding cellular tissue becomes at first 
tumid, afterwards solid and firm, lastly, soft, as the other parts 
have become. In the centre of the softened mass a little depot of 
matter forms (a pustule), having its seat partly in the lymphatic 
vessel, partly in the cellular tissue, and separated from other 
pustules above and below it by the valves. In places where the 
skin is very thin — on the lips, nose, insides of the thighs, &c. — 
Leblanc observes, farcy-buds are in general smaller than in parts 
clothed by thick skin. This, I imagine, is owing to the scantiness 
or tensity of cellular membrane in such parts. 
The Character of the Farcy-bud is well described by 
Rodet. “ Detach a moderate-sized farcy-bud of recent form- 
ation, and before the softening process has commenced in it, and 
cut into this firm, indolent, rounded, isolated, completely formed 
bud, and its interior will be found composed of a hard, fibrous, 
condensed, milk-white tissue, resisting the bistouri ; and though 
exhibiting throughout, in certain cases, a homogeneous texture, is 
nevertheless, in other instances, found grooved and penetrated 
by sanguineous capillaries. At a rather later period than this,
