softened condition in the living horse, they are exceedingly 

 prone to become lacerated or ruptured in their tissues if the 

 animal be put to greater exertion than ordinary. The blood, 

 however, which is mixed with the urine, and which is the 

 characteristic feature of the malady, does not in all eases come 

 from the kidneys. In a case which very lately came under my 

 treatment, and which I carefully examined after death, I dis- 

 covered that the blood had been exuded principally from the 

 inner surface of the ureters. 



The patient was an aged cab mare, and the bleeding came 

 on in consequence of the animal being exerted beyond her 

 strength. The appearance of the blood was very singular, and 

 worthy of notice. It was coagulated in the urine, and every 

 time the animal parted with water the blood came away in rolls, 

 the length and thickness of which was about that of a black- 

 lead drawing pencil. This led me in the iirst instance to sus- 

 pect that the blood came from the ureters. The patient, in 

 consequence of being very old, was destroyed, and the post 

 mortem examination confirmed my surmise : the ureters were 

 injured, and also filled with congulated blood ; the kidneys were 

 softened, but not otherwise deranged. 



Another case which came under my care was that of a very 

 old draught horse. The animal was injured in consequence of 

 being compelled to drag a heavy load of manure through a 

 quantity of soft clay. The blood came away in small irregular 

 formed clots. The subject of this case recovered under the use 

 of cold water cloths applied across the loins, associated with 

 rest, and the internal use of lactic acid. 



Teeatment. — All that can be done in the generality of 

 cases may prove but temporary. If the patient is old, and the 

 kidneys softened, more than temporary relief cannot be expected.
