208 CAUSES OF GLANDERS. 



not being in a state of readiness. Now, these stables Avere newly 

 erected ones, notwithstanding which, great numbers of the horses, 

 though previously in perfect health, soon after entering them, be- 

 came diseased : the greater proportion contracted grease, but several 

 were attacked with glanders and farcy. He has since also received 

 peculiarly ^satisfactory evidence of this in two memorable instances, 

 in which stables that were hot and foul, and had from time to 

 time turned out several glandered horses, were rendered equally 

 salubrious with others adjoining them by proper ventilation and 

 attention to cleanliness." 



" By this time v^^e shall have received some striking illustrations 

 of what was advanced in the outset, that every animal poison is 

 regulated in its operation by its own peculiar laws : were it not, 

 most wisely, so ordained, the whole animal creation must long 

 before now have been exterminated. If man had been susceptible 

 of contracting diseases from horses, oxen, hogs, sheep, dogs, S^c, 

 and these animals, in their turn, could have taken human disorders, 

 all must have lived only to act their dreadful parts in the work of 

 universal devastation." 



"We now come to the relation of that celebrated experiment of 

 the Professor's, by which not only the contagious, but the consti- 

 tutional nature of glanders is proved beyond all doubt and idle 

 speculation — that experiment which goes to disprove the assump- 

 tion of Mr. Hunter, that the blood itself was never diseased. Of a 

 horse affected with acute glanders the Professor laid bare the 

 carotid artery and jugular of the same side, and around each 

 vessel placed a ligature. A pipe furnished with a stop-cock was 

 then inserted and fastened into the artery, which was made to 

 communicate through the medium of an elastic tube — an ureter, I 

 believe — with another pipe introduced into the jugular vein of an 

 ass ; this animal having been previously bled until he had fallen 

 from exhaustion. In this manner blood was conveyed from the 

 artery of the horse into the vein of the ass until the latter evinced 

 signs of perfect resuscitation. A circumstance occurred, however, 

 in the revival of the ass, which, though it did not affect the issue 

 of the experiment, may serve as a warning to future experiment- 

 alists ; and that was, that in consequence, as it was thought, of
