SEAT AND NATURE OF GLANDERS. 269 



tlie sinuses is rarely found tuberculated. Tubercles have, however, 

 been observed in the lungs, lymphatic glands, cellular membrane, 

 skin, testicles, lining membrane of the alimentary canal, &c. 

 Should glanders be complicated with a tuberculous affection of the 

 lungs, the animal coughs frequently, tires soon, perspires readily : 

 latterly he loses his vigour and energy, becomes washy, soft, and 

 lazy; subject to catarrh, ophthalmia, cutaneous eruptions, farcy, 

 oedema, &c. And now, soon, glanders becomes complicated with 

 farcy. Farcy huds are nothing else hut scrofulous tubercles : they 

 grow, develop, and decline, the same as pulmonary tubercles. 

 Glanders hears, therefore, the closest analogy to phthisis in man. 

 The phthisis of the pituitary membrane will sometimes turn of a 

 cancerous nature ; at other times it has been known to become 

 typhoid." 



Farcy, Dupuy regards as the same " tubercular affection" as 

 glanders, notv/ithstanding it is " often local and an original affec- 

 tion ;" and on this account "it admits of being cured, while 

 glanders has resisted every remedial means hitherto used." When 

 we find one veterinarian declaring farcy to be curable, another in- 

 curable, " the probability is, they have been treating different va- 

 rieties of the same disease : in one case the farcy may have been 

 local, in the other constitutional" 



Of the Pulmonary Tubercle, Dupuy has observed '' three 

 varieties, the miliary, the pisiform, and the unciform. Each 

 tubercle is composed of an envelope or cyst, and of a whitish 

 substance easily crushed between the fingers, which Messrs. 

 Dulong and Labillardiere have found to resemble osseous matter. 

 Very considerable depositions of this bony substance are occasionally 

 seen in the proper pulmonary tissue, especially in the ox species. 

 When the tubercles are of the large kind their number is limited ; 

 but the miliary species are innumerable. While forming., they 

 are firm, organized, and always found in the course of the blood- 

 vessels, whose caliber is singularly augmented. They grow and 

 become developed like any other organized bodies, without our 

 being able to offer any rationale of the process, or of the space of 

 time they continue organic, prior to their mollification and degenera- 

 tion. They commonly end in ulceration and destruction of the
