ment._--The treatment is mainly in the change of diet to a more solid
aliment destitute of the special, offensive ingredient. Boiled flaxseed is
often the best diet or addition to the wholesome dry food, and, by way of
medicine, doses of 2 drams each of sulphate of iron and iodid of potassium
may be given twice daily. In obstinate cases 2 drams ergot of rye or of
catechu may be added.

BLOODY URINE (RED WATER, MOOR ILL, WOOD ILL, HEMATURIA, HEMAGLOBINURIA).

This is a common affection among cattle in certain localities, above all on
damp, undrained lands and under a backward agriculture. It is simply bloody
urine or hematuria when the blood is found in clots, or when under the
microscope the blood globules can be detected as distinctly rounded,
flattened disks. It is smoky urine--hemaglobinuria--when neither such
distinct clots nor blood disks can be found, but merely a general browning,
reddening, or blackening of the urine by the presence of dissolved,
blood-coloring matter. The bloody urine is the more direct result of
structural disease of the kidneys or urinary passages (inflammation, stone,
gravel, tumors, hydatids, kidney worms, sprains of the loins), while the
stained urine (hemaglobinuria) is usually the result of some general or
more distinct disorder in which the globules are destroyed in the
circulating blood and the coloring matter dissolved in and diffused through
the whole mass of the blood and of the urine secreted from it. As in the
two forms, blood and the elements of blood escape into the urine, albumin
is always present, so that there is albuminuria with blood-coloring matter
superadded. If from stone or gravel, gritty particles are usually passed,
and may be detected in the bottom of a dish in which the liquid is caught.
If from fracture or severe sprain of the loins, it is liable to be
associated not only with some loss of control of the hind limbs and with
staggering behind but also with a more or less perfect paralysis of the
tail. The bloodstained urine without red globules results from specific
diseases--Texas fever (Pl. XLVII, fig. 3), anthrax, spirillosis, and from
eating irritant plants (broom, savin, mercury, hellebore, ranunculus,
convolvulus, colchicum, oak shoots, ash privet, hazel, hornbeam, and other
astringent, acrid, or resinous plants, etc.). The Maybug or Spanish fly
taken with the feed or spread over a great extent of skin as a blister has
a similar action. Frosted turnips or oth
