mucous membranes of the organism generally. It also occa- 

 sionally associates itself with a form of disease closely resem- 

 bling Strangles. This, perhaps, is to be regarded as its most 

 dangerous association, inasmuch as the latter may entirely mask 

 the insidious operations of the former. 



When the disease has passed into its more malignant states, 

 the blood speedily becomes loaded with poisonous materials, 

 which the system will imbibe more or less ; and those structures 

 requiring the most blood to properly and efficiently continue 

 their healthy function, (and which ia themselves are the most 

 vascular), will, as a matter of course, speedily become partici- 

 pators in the morbid change. Thus we frequently find, in this 

 disease, that the patient will exhibit symptoms of abdominal 

 disease of a very low or sub-acute character ; the animal will 

 occasionally regard his side anxiously ; sometimes he wiU paw 

 the ground and lie down, and when down he is seldom or ever 

 violent. As the disease becomes more confirmed, the animal is 

 affected with purging, and the faeces are mixed with black semi- 

 fluid blood, from which is emitted a most intolerable stench. 



Pathognomonic Sxmpxoms.— The excessive general debility 

 of the patient ; the faint, suffocative cough ; the tremulous motion 

 of the shin, and sub-textures covering the chest ; the rales within 

 the windpipe and bronchial tubes ; and, above all, the presence of 

 a peculiar fainth/ putrid effluvium from the body of the patient. 



PKoaNOSis.^ — "We must be guided in our prognosis by the 

 nature of the attack, by the character of the pulse and the 

 respirations, by the appetite, and the debility. If the attack be 

 mild — if the pulse becomes reduced in the number of its 

 beats, accompanied with a corresponding decrease of the respi- 

 ratory acts — if the appetite is restored, and the animal lies
