oduct is that of the wasting flesh.

The other products containing nitrogen are present in only small quantities
and need not be specially referred to. The urine of cattle contains much
less of carbonates than that of the horse, and effervesces less on the
addition of an acid. As the carbonates form a large proportion of the solid
deposits (gravel, stone) from the horse's urine, the ox may thus be held
less liable, yet even in the ox the carbonates become abundant or scanty,
according to the nature of the feed, and therefore gravel, formed by
carbonate of lime, is not infrequent in cattle. When fed on beets, clover
hay, or bean straw carbonates are present in large quantities, these
aliments being rich in organic acids and alkaline carbonates; whereas upon
oat straw, barley straw, and, above all, wheat straw, they are in small
amount. In calves fed on milk alone no carbonates are found in the urine.

Phosphates, usually in combination with lime, are, as a rule, present only
in traces in the urine of cattle; however, on a dietary of wheat, bran, or
other aliment rich in phosphates, these may be present in large amount, so
that they render the liquid cloudy or are deposited in solid crystals. The
liquid is rendered transparent by nitric acid.

The cow's urine, on a diet of hay and potatoes, contained:

Potassium bicarbonate 16.1
Magnesium carbonate 4.7
Lime carbonate 0.6
Potassium sulphate 3.6
Common salt 1.5
Silica Trace
Phosphates 0.0
Water and undetermined substances 921.3

The following table after Tereg[1] gives the different conditions of the
urine, and especially the amount of urea and hippuric acid under different
rations. The subjects were two oxen, weighing, respectively, 1,260 pounds
and 1,060 pounds:
