From a full consideration of all the facts and circumstances which his 

 investigation had revealed, he was constrained to look upon the term 

 "Azoturia" as a misnomer which could not be sustained in any sense 

 whatever. 



Causes. The immediate cause of the disease is in some way connected 

 with good living, and the blood has been stated to be surcharged with 

 nitrogenous matter. This is very likely to be the case, but there is no 

 scientific proof of the truth of the proposition. That a change is induced 

 in the blood by a short period of work after two or three days' rest is 

 true, and whatever that change may be it is marked by an escape of 

 albumen and colouring-matter of the blood with the urine. 



Symptoms. The attack is usually very sudden; the subject may all 

 at once become dead lame behind, as if from a broken limb, or severe injury 

 to the loin; the muscles of the quarter are spasmodically contracted and 

 hard, the animal breaks out into a profuse 

 sweat, and the breathing becomes hurried 

 and difficult. There is great discoloration 

 of the urine, which may be of a dark-red 

 or even porter colour. Sometimes there 

 is difficulty in staling, when it becomes 

 necessary to empty the bladder by means 

 of the catheter. In a short time the 

 animal falls, and is unable to rise. While 

 on the ground he fights convulsively with 

 the fore-limbs, and raises his head to his 

 side as if suffering abdominal pain. The 

 membranes of the eyes and nose are intensely 

 reddened, the pulse is quick and full, and the temperature increased. 



Treatment. A bold dose of aloes should be promptly administered, 

 and, if possible, the animal should be slung. This is one of the few 

 diseases in which some veterinary surgeons advise bleeding; no doubt 

 the readiest way to reduce any deleterious matter which the blood may 

 contain. A sack containing a large quantity of hot bran or other poultice
