218 ALBUMINOUS URINE. 
The author was once prepossessed in favor of iodide of potassium 
for the cure of diabetes. He is indebted to Mr. Woodger, the excel- 
lent practical veterinary surgeon of Paddington, for a knowledge of the 
very superior efficacy of the drug just named. It exercises a potent 
action over the kidneys, at the same time it is a first class tonic, and in 
a surprising manner reduces the desire for fluids. It is in all respects 
the exact medicine which could be wished for in a case of diabetes 
insipidus. 
ALBUMINOUS URINE. 
Two cases of this description occurred in the extensive practice of the 
late William Percivall, Esq. They are narrated in the admirable work 
entitled ‘“Hippopathology,” bequeathed to posterity by the estimable 
author. The present writer having been honored by the friendship of 
the gentleman named, is, from frequent conversations upon the subject, 
the better able.to describe and to depict the disorder. 
The positions of both horses were remarkable. One stretched the 
fore and hind legs out, 
as though it were about 
to urinate; the other 
roached the back and 
brought the hind feet 
under the body as far as 
possible. Turning in the 
stalls was, in each case, 
accomplished with diffi- 
culty; and the straddling 
gait remarkable in both, 
indicating the seat of the 
affection. 
Some urine being 
caught by the groom, it 
was thick but clear—like melted calves’ foot jelly—and, when cold, the 
surface was uneven. Bichloride of mercury being added to a portion 
of the fluid, caused a thick, colorless, opaque substance —resembling 
coagulated white of egg—to be thrown down, leaving a clear straw- 
colored liquor above the settlement. Another portion being first 
treated with acetic acid, afterward mixed with prussiate of potash and 
subsequently boiled, became in appearance like to milk. With time, 
however, a white sediment occurred, leaving the fluid perfectly clear. 
Mr. Percivall’s treatment was mildly depletive. He bled moderately, 
gave a laxative, and applied mustard to the loins for a brief space.
