NATURE OF GLANDERS. 



Of the forty authors whose opinions I have sought on the sub- 

 ject, no one, to my seeming, has framed a more truth-like pathology 

 of glanders than M. Leblanc : a French veterinarian of considerable 

 repute in his own country, and very far from being unknown in ours. 

 In 1839, Leblanc published at Paris a small work* which, by acci- 

 dent, came into my possession a few months ago, wherein, to my 

 great gratification, I found notions entertained such as for many a 

 year had been floating about in my own mind ; though with me they 

 were, confessedly, rather the offspring of inductive reasoning from 

 certain admitted facts, than of any such practical demonstration as 

 they appear to have since received in the hands of Leblanc. 



Coleman, long ago, proved beyond any reasonable ground for doubt, 

 that glanders and farcy were identical diseases, or, rather, the same 

 disease affecting different parts of the body ; and yet — which was 

 singular enough — he never, on any occasion that I recollect, went 

 so far as to say that the pimple or tubercle or chancre of glanders 

 was in reality di farcy-hud or a farcy-ulcer. The proofs of identity 

 in nature between glanders and farcy rest upon — 1st, their reci- 

 procity of production through inoculation ; 2dly, their traceableness 

 to the same causes; 3dly, their termination one in the other, which 

 almost invariably takes place, when they are suffered to run their 

 natural course, previous to death ; 4thl3^, their frequently simultane- 

 ous appearance in the same subject, together with the similitude of 

 the phenomena and course they exhibit. 



Assuming it, then, as proved, that farcy and glanders are in 

 their nature but one and the same disease affecting different parts 

 of the body, and it being admitted that farcy is a disease affecting 

 the lymphatic system, it of course follows that glanders can be no 

 other than disease of the same system of vessels ; and, supposing 

 that this were proved, it would also follow that the pimples we 

 see rising upon the septum nasi after inoculation for glanders, and 

 on occasions in idiopathic glanders as welL and which Dupuy called
