CAUSES OF G LANDERS. 215 



as persons without any knowledge of such matters are apt to 

 believe*." 



You ATT, 1832: — "The main cause," — "the grand cause of glanders 

 is CONTAGION." — " I advisedly call it 'the grand cause,' for I beHeve 

 I shall be able to render it probable that glanders arise oftener from 

 contagion than from any other sourcet." 



Vines, 1833, in section 3 of chapter V of his work|, treating of 

 "The Infectious or Contagious Nature of Glanders and Farcy," re- 

 marks, in a note explanatory of the meaning and application of the 

 words infection and contagion, "as we have never seen a case, and 

 are unacquainted with an instance where glanders or farcy was pro- 

 duced by inhaling the breath or effluvia of the body of another 

 animal, hut only hy actual contact of matter, we shall, like Smith 

 and Dupuy, use the terms synonymously." (P. 157.) — "Mr. 

 Coleman," says Mr. Vines, " attributes the infection or contagion 

 to a sjoecific poison in the blood ; and he also asserts that a similar 

 poison exists in those animals where glanders or farcy is generated; 

 that it is formed in the atmosphere of stables by the secretions and 

 excretions of the animal, and that it is a comjjo of clung, urine, breath, 

 and perspiration, ^wi, in my opinion, an}'' impure air which may 

 be thus formed, only tends to render the system debilitated and 

 unhealthy ; and that from this cause, as well as from a variety of 

 others, the blood and fluids lohich are formed are rendered vitiated 

 or unnatural, and of an infectious or contagious character, and ca- 

 pable of producing general derangement or disease, if introduced 

 into the system of some other animals, especially the ass, ichich is 

 almost naturally predisposed to the disease from bad feeding, and 

 the weak texture of its skin. Thus far only, then, do I consider the 

 discharge in glanders and farcy infecfious, and not in consequence 

 of an independent j^oison in the bloods (P. 157, 158). — '' If it is 

 contended that, by inoculating with the matter of" glanders and 

 farcy, the proper symptoms are produced, and that the fact is then 

 proved, and that a specific poison thus existed, and that this poison,
