in the urine, the suspected and frothy liquid must be
rendered sour by adding a few drops of nitric acid and then boiled in a
test tube. If a solid precipitate forms, then a few more drops of nitric
acid should be added, and if the liquid does not clear it up it is albumin.
A precipitate thrown down by boiling and redissolved by nitric acid is
probably phosphate of lime.
_Treatment._--Treatment is usually directed to the disease on which it is
dependent. In the absence of any other recognizable disease, mucilaginous
drinks of boiled flaxseed, slippery elm, or gum may be given, tannic acid,
one-half dram twice daily, and fomentations or even mustard poultices over
the loins. When the disease is chronic and there is no attendant fever
(elevation of temperature), tonics (hydrochloric acid, 6 drops in a pint of
water; phosphate of iron, 2 drams, or sulphate of quinin, 2 drams, repeated
twice daily) may be used. In all cases the patient should be kept carefully
from cold and wet, a warm, dry shed, or in warm weather a dry, sunny yard
or pasture being especially desirable.
SUGAR IN URINE (DIABETES MELLITUS).
This is a frequent condition of the urine in parturition fever, but as a
specific disease, associated with deranged liver or brain, it is
practically unknown in cattle. As a mere attendant on another disease it
demands no special notice here.
INFLAMMATION OF THE KIDNEYS (NEPHRITIS).
This has been divided according as it affects the different parts of the
kidneys, as: (1) Its fibrous covering (perinephritis); (2) the secreting
tissue of its outer portion (parenchymatous); (3) the connective tissue
(interstitial); (4) the lining membrane of its ducts (catarrhal); and (5)
its pelvis or sac receiving the urine (pyelitis). It has also been
distinguished according to the changes that take place in the kidney,
especially as seen after death, according to the quantity of albumin in the
urine, and according as the affection is acute or chronic. For the purpose
of this work it will be convenient to consider these as one inflammatory
disease, making a distinction merely between the acute and the chronic or
of long standing.
The _causes_ are in the main like those causing bloody urine, such as
irritant and diuretic plants, Spanish flies applied as a blister or
otherwise, exposure to cold and wet, the presence of stone or gravel in the
kidneys, injuries to the back or loins, as by riding one another, the
drinking of al
