eneral and local styptics. Irritants in feed must be
avoided, sprains appropriately treated, and stone in bladder or urethra
removed. Then give mucilaginous drinks (slippery elm, linseed tea)
freely, and styptics (tincture of chlorid of iron 3 drams, acetate of
lead one-half dram, tannic acid one-half dram, or oil of turpentine 1
ounce). If the discharge is abundant, apply cold water to the loins and
keep the animal perfectly still.

HEMOGLOBINURIA (AZOTURIA, AZOTEMIA, POISONING BY ALBUMINOIDS).

Like diabetes, this is rather a disease of the liver and blood-forming
functions than of the kidney, but as prominent symptoms are loss of
control over the hind limbs and the passage of ropy and dark-colored
urine, the vulgar idea is that it is a disorder of the urinary organs.
It is a complex affection directly connected with a plethora in the
blood of nitrogenized constituents, with extreme nervous and muscular
disorder and the excretion of a dense reddish or brownish urine. It is
directly connected with high feeding, especially on highly nitrogenized
feed (oats, beans, peas, vetches, cottonseed meal), and with a period of
idleness in the stall under full rations. The disease is never seen at
pasture, rarely under constant daily work, even though the feeding is
high, and the attack is usually precipitated by taking the horse from
the stable and subjecting it to exercise or work. The poisoning is not
present when taken from the stable, as the horse is likely to be
noticeably lively and spirited, but he will usually succumb under the
first hundred yards or half mile of exercise. It seems as if the
aspiratory power of the chest under the sudden exertion and accelerated
breathing speedily drew from the gorged liver and abdominal veins
(portal) the accumulated store of nitrogenous matter in an imperfectly
oxidized or elaborated condition, and as if the blood, surcharged with
these materials, were unable to maintain the healthy functions of the
nerve centers and muscles. It has been noticed rather more frequently in
mares than horses, attributable, perhaps, to the nervous excitement
attendant on heat, and to the fact that the unmutilated mare is
naturally more excitable than the docile gelding.

Lignieres has found in hemoglobinuria a streptococcus which produced
nephritis, bloody urine, and paraplegia in experimental animals,
including horses.

_Symptoms._--In the milder forms this affection may appear as a lameness
