SEAT AND NATURE OF GLANDERS. 271 



Morel, 1823, denies the specificity of glanders, regarding the 

 disease as no more than tlie natural consequence of chronic inflam- 

 mation of the mucous lining of the aerial passages*. 



Gerard, 1827, asserts the identity of glanders and farcy. 

 " Glanders," he says, ** is no more than/arcy in the nose. And 

 the farcy-buds and pimples observable upon the pituitary mem- 

 brane constitute lesions of the same description, in both instances 

 succeeded by ulcerationt." 



RODET, 1830, the Veterinary Professor at Toulouse, adopted the 

 Dupuy theory, but with such important modifications as gave it a 

 more regular and systematic form. Admitting tubercles to con- 

 stitute the especial and proximate cause of glanders, he — not 

 leaving us, as Dupuy has, in doubt — ascribes their origin to a con- 

 stitutional influence, dependent upon a lymphatic temperament, 

 vicious conformation, hereditary disposition, or upon accidental 

 causes, such as the relapse and chronic prolongation of diseases at 

 first acute and of a different nature ; from which it follows that 

 glanders may be either constitutional or acquired. The former will 

 be primitive or secondary, according as the tuberculous affection 

 has its seat exclusively or at least originally in the pituitary, or 

 as that membrane becomes affected through extension of the disease 

 from the lungs; the latter — or acquired disease — will be the result 

 and producer of phlegmasial irritations, repeated or more or less 

 protracted, sometimes in the pituitary alone, but oftener, if not 

 always, in the mucous membrane lining the air-passages, a cir- 

 cumstance which, at the time that the degeneration (of tubercles) 

 exists nowhere but in the nose, goes far to shew that glanders is an 

 affection purely consecutive to these same irritations." — In fine, 

 according to Rodet, glanders is no more than a symptomatic dis- 

 order — "a morbid state ever consequent upon other diseasej." 



Benard, in some researches he made into the nature of the 

 blood in glandered horses, disco veered albumen to be predominant 

 in it according to the length of time the disease had existed, and
