NAIURE OF GLANDERS. 1")\ 



the midddle of the pulmonary crepitating tissue. They consist of 

 deposits of albuminous matter, solid or liquid, inclosed within cysts 

 of palish grey aspect, which, perhaps, are nothing more than air- 

 vesicles whose walls have acquired morbid thickness. They fre- 

 quently commence by red points, whose centres, in time, turn 

 white, remaining for awhile enveloped in a red case. At length 

 the inclosed matter suddenly becomes softened, then hardens again, 

 and turns of a calcareous nature." 



Such is Leblanc's practical exposition of the nature of glanders 

 and farcy. The important novelty in it, is, that he has brought 

 forward proofs, as far as morbid anatomy with the aid of che- 

 mistry would supply them, that glanders, like farcy, is a disease 

 of the lymphatic system ; that the pimples or tubercles observ- 

 able in the incipient stages of glanders are nothing more than so 

 many farcy-buds, which in time become pustules, and burst, 

 and end in turning to so many open, foul, spreading ulcers. 

 Dupuy regarded glanders as identical in nature with farcy; but 

 then he confounded both — along with other diseases, such as 

 phthithis pulmonalis, strangles, &c. — under the appellation of ^?^6er- 

 culous disease ; and, so far from telling us that the tubercle is a 

 farcy-bud, insists upon the farcy-bud being a tubercle : '' farcy- 

 buds," says he, " are nothing else but scrofulous tubercles ; " ad- 

 mitting, however, that tubercles are organic productions ; and that 

 " they are found in the greatest numbers in the course of the large 

 veins pervading the septum," — " pursuing the course of the large 

 bloodvessels :" the very course we know the lymphatic vessels 

 take. 



Assuming, then, that the lymphatic, vessels, together with their 

 glands, are the parts primarily or essentially diseased in glanders 

 and farcy, it next becomes our business to inquire in what the 

 morbid action consists, and, if we can, to find out in what part or 

 tissue of the lymphatic vessel it originates, or is principally seated. 

 Coleman regarded farcy as a specific inflammation besetting the 

 internal coat of the lymphatic vessel ; and, considering the heat, 

 and swelling, and tenderness of a farcy-cord at its first forma- 

 tion, and the ordinary conversion of the buds from a hard into a 

 soft state, and the final change of them into pustules or abscesses —
