22 ACUTE INFLAMMATION' OF THE KIDNEYS, &C. 
the region of the kidneys still more painful, both on the right and 
left side. In the course of the day the animal endeavoured re- 
peatedly to urine without voiding any thing. On examining the 
rectum, I found the bladder to be empty. Throughout the whole 
course of the disease the dung was regularly voided in moist solid 
balls. 
As the symptoms above narrated plainly shewed that the dis- 
ease was inflammation of the kidneys, I subtracted eight pounds 
of blood from the animal, and administered Glauber’s salts §viij 
with cream of tartar and linseed of each §ij, made into an electu- 
ary, in doses of a table-spoonful every hour. In the course of the 
morning I had the regions about the kidneys repeatedly bathed 
with vinegar, and, in the afternoon, put on a mustard plaster, which 
I suffered to remain there for twelve hours. 
On the following morning all the inflammatory symptoms were 
considerably diminished, but the stiffness of the back between the 
hip-bones remained the same ; no escape of urine had taken place, 
the bladder still continued empty ; but the animal appeared rather 
more lively, and its appetite was a little increased. 
I continued to give the same medicine, with the exception of 
the Glauber’s salts, and every hour caused a mucilaginous clyster 
to be administered, and another mustard plaster to be laid on the 
regions of the kidneys. 
On the third day nearly all traces of fever were vanished, the 
motion of the portion of the back between the hip-bones was more 
free, the lameness of the right hind leg diminished, the animal to- 
lerably lively, and ate with some degree of appetite ; but the blad- 
der still continued empty, and no evacuation of urine took place. 
We gave some green meat and a bran mash, and administered 
an electuary composed of sal ammoniac and linseed powder. I also 
caused a mucilaginous clyster to be given every three hours, and 
the regions about the kidneys washed with vinegar. In the 
evening of this day a slight evacuation of thick milky urine took 
place, which increased in the course of the night, and on the 
following day the secretion and evacuation of urine was restored 
nearly to its natural state, and the animal to health. The lameness, 
which had evidently been merely a symptom attendant on the dis- 
ease, had also vanished. At night I merely gave sal ammoniac and 
gentian. 
On inquiring into the probable causes of this disease, I traced it 
very distinctly to the eating of some hay got in about four weeks 
before. This hay had been grown in the spring on a meadow 
that had been flooded, and was very luxuriant. The grasses of 
which it consisted were good, and had been well mown, and 
brought in tolerably dry. In the loft, however, the trusses were
