Urine.—The mean daily quantity of urine voided in the observation period was 683 c.c.;
it decreased slightly during the latent period, 641 c.c. In the paroxysms and intermissions
there was a decrease of 29 per cent. compared with the observation period. During the whole
case (101 days), a daily average of 569 cc. was passed.
The maximum daily output during paroxysms was 775 c.c. and minimum 330 c.c.; in the
intermissions it was 780 c.c., 260 c.c., respectively.
Urea.—The mean excretion of Urea in the observation period was 2.86 grammes with a
maximum of 5.07 grammes and minimum of 0.87 grammes. It increased slightly in the
latent period, 2.96 grammes, but there was a considerable increase during paroxysms and
intermissions, viz., 4.03 and 3.66 grammes respectively. The maxima being 9.24 grammes,
8.58 grammes, the minima being 2.31 grammes, 1.56 grammes, for paroxysms and intermis-
sions, respectively. The mean daily Urea excreted during the 101 days, the animal was under
observation, was 3.07 grammes.
Hippuric Acid.—In the period of observation extending over 72 days a mean average
quantity of 32.23 grammes was excreted daily. During the latent period there was a decrease
amounting to 30 per cent., whilst in Paroxysm I and Intermission I the decrease was 27 per
cent., and 13 per cent. respectively. From the latter period there was a gradual dimunition in
the amount of Hippuric Acid passed, viz., 58 per cent. at the end of Intermission III.
The following were the mean daily averages for different periods :—

Albumen.—No Albumen appeared in the urine during the whole case.
Total Solids in the Urine.—The mean daily output during 101 days was 59.09 grammes.
The maximum mean daily quantity of the different periods, 72.96 grammes, was passed in the
observation period, whilst the minimum mean daily quantity, 45.49 grammes, was passed
during Intermission III.
The total solids consisted chiefly of carbonate of lime in suspension in the Urine, and Hip-
puric Acid, Urea and Mucin, etc., in solution. During the course of the disease there was a
gradual falling off in the amount of total solids in the urine—from 72.96 grammes in the
observation period to 45.49 grammes in Intermission III.
The ratio of the total solids in the different periods was:—

during the whole case were 82° and 32° respectively.
