34 THE IMPROVED ART OF FARRIERY. 



of holding the subject of Glanders and Farcy up by the 

 wrong end. It is true, they have, at times, sHghtly 

 noticed the disorganisation of the natural parts of the 

 body, such as the diseased state of the lungs, mem- 

 brane of the nostrils, and cavities of the head, as well 

 as of the skin. But, then, those gentlemen have been 

 also accustomed to consider these diseased appearances 

 as the effect of a specific poison, and not as dependent 

 on, and caused by, a variety of predisposing and ex- 

 citing causes, which, in the first instance, have the 

 effect of producing organic disease in all its various 

 forms, and of which that state of the system, com- 

 monly called Glanders and Farcy, is nothing more than 

 the sequel or common follower." 



In certain cases where these diseases have sometimes 

 presented themselves in a less formidable aspect than 

 usual, they have consequently been far less contagious 

 than in other cases ; hence arose a difference of opinion 

 as to their contagious nature, which some authors 

 doubted, more especially as regards Farcy, and among 

 these are Mr. Smith, and M. Dupuy ; and Mr. Vines 

 asserts he " never knew of a case which could be 

 fairly attributed to infection through any inhalation 

 from another horse." 



Glanders, 



May properly be considered of two kinds : — 



1st. — ^When the mucous membrane which lines the 



nostrils and the cavities of the head only is affected. 

 2nd. — When the lungs are likewise diseased, being 



covered wit^ tubercles, &c. 



Causes. — When the disease is confined to the head
