Diseases of the Urinary Organs. on 
more especially when such symptoms are present on one 
side only.” 
“Vesical hemorrhage may be so profuse as to furnish 
blood tolerably pure from the urethra. Andin general this 
variety of hematuria may be known by the blood not being 
mixed with the urine ; the latter fluid passes off first, toler- 
ably pure; and the blood comes last, more or less changed 
by mixture with the residue of the urine. It is also known 
by the absence of renal symptoms, and by the presence of 
undoubted signs of stone in the bladder, or other disease 
of that viscus, or of affection of the prostate. 
“ From the Urethra.—In this case there is absence of both | 
renal and vesical symptoms; the blood passes pure, irre- 
spective of any desire to. evacuate the bladder.” 
Treatment—Hematuria demands prompt and active 
measures ; nothing irritative must be administered, drastic 
purgatives, and especially diuretics, should be strictly 
avoided. The preparations of iron and barks are the most 
suitable agents for this disease. Mucilaginous drinks, as 
thick barley-water, solution of gum acacia, or beef-tea 
thickened with isinglass, can be given freely, together with 
the use of hot fomentations or linseed-meal poultices to 
the loins ; or counter-irritants, as mustard or ammonia em- 
brocations. Sedative enemas may also be administered 
where the irritation is considerable. 
Bleeding, under all circumstances is unnecessary, and is 
strongly contra-indicated. 
RENAL CALCULI. 
Occasionally stones are found in the kidney of the dog, 
composed chiefly of uric acid, ammonia, or phosphate of 
lime, and containing as a nucleus some foreign matter. 
Renal calculi vary in shape, sometimes being oval and an 
exact cast of the pelvis of the kidney, at others irregular 
in shape and variously formed, according to the position 
they had occupied. c
