chap, in.] glanders: of three sorts, &c. 367 



and to ascertain with precision that species of the 

 disorder with which the animal is affected ? 



(t After much experience on the subject of the 

 diseases of horses, we are convinced that it is neces- 

 sary to distinguish three sorts of glanders, namely, 

 The first sort, or merely swelling of the glands, 

 with a pale running, which is the glanders pro- 

 perly so called ; the second is no other than some 

 disorder* circulating in the mass of blood ; and the 

 third may be denominated the farcy glanders. 

 Glanders of the first kind is not infectious, except 

 it be complicated with other disorders ; but this is 

 seldom the case, though we may daily witness 

 horses thus attacked abandoned as incurable, or 

 with little more humanity put to death. On the 

 contrary, glanders of the second species is com- 

 municable, because the horse, besides running at 

 the nose, and becoming glanderous, has likewise 

 chancres, and these chancres appear to be the only 

 proximate cause of contagion. 



" The third species of glanders is in like manner 

 contagious, because it not only occasions a running 

 of the nose, but the tumefied glands and the car- 

 tilage of the nose become chancred, and certain 

 parts of the body are likewise covered with lumps 

 and chancres, which latter characterise the farcy 



* We might have rendered this into English, as " some disorder 

 in the functions of the lymphatic glands, which being unperformed 

 aright, affects the circulation, or mass of the blood." This disorder 

 is termed the humours vitiated.
