and even inflammation of the kidneys may occur. _Treatment._--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 other roots will bring on the affection in some subjects. Among conditions which act by the direct destruction of the globules in the circulating blood may be named an excess of water in that fluid; the use of water from soils rich in decomposing vegetable matter and containing alkaline salts, particularly nitrites; and the presence in the water and feed of the ptomaines of bacteria growth; hence the prevalence of "red water" in marshy districts and on clayey and
