292 NATURE OF GLANDERS. 



the same as happens with any common pustular tumor of the cellu- 

 lar membrane — there can be no doubt but that the morbid process 

 is, during this stage at all events, of an iiiflammatory nature ; and 

 that it is specific as well, we argue from the fact of the pus or 

 matter produced by it being capable of procreating the disease 

 (either glanders or farcy) in another of the horse species. We are 

 assured by Leblanc, that this bud, whether it be a farcy-bud or a 

 glanders-bud, and be, as the latter, denominated either pimple or 

 tubercle, consists of albuminous matter ; and that, when the usual 

 conversion of this into purulent matter does not follow, calcareous 

 deposit has been found: thus satisfactorily accounting for the 

 degeneration of farcy-buds into hard callous tumours or tuber- 

 cles, and, perhaps, likewise explaining the pathology of such glan- 

 derous affections as we denominate chronic, on account of their 

 length of duration without breaking forth into the ulcerative 

 stage. The irregular, knotted appearance, of the farcy-cord, 

 that appearance of it which first, no doubt, gave rise to the appel- 

 lation oi farcy-buds, was accounted for by Coleman, out of the cir- 

 cumstance of the valves — which we know to be very numerous in 

 the lymphatic vessel — not being susceptible of the specific inflam- 

 mation ; " for if one of these diseased vessels be examined," said 

 the late Professor, " perfectly sound partitions of membrane will 

 be found between the knots, which cannot be any thing else but 

 the valves*." 



Whether the jiulmonary glanderous tubercle is to be regarded 

 as no more in its nature than a farcy-bud, and whether the pul- 

 monary tubercle of glanders bears any, and how much, analogy to 

 the tubercle of phthisis pulmonalis, are questions not so easily 

 solved. Leblanc assures us, as far as his examinations have gone, 

 of the identity of the former ; but he is silent in regard to the 

 latter, although Dupuy hesitates not to pronounce them in nature 

 both alike. For my own part, I feel disposed to think, that the 

 production which is taken for and called a pulmonary tubercle in 

 glanders or farcy, but which may turn out to be nothing but a por-
