BULL V.
Corpuscular changes in the Blood.
Red Corpuscles.—Taking the mean daily number during the period of observation as
100, there was an increase of 6.2 per cent. in the latent period. These numbers decreased 5.3
per cent. and 7.1 per cent. in the paroxysms and intermissions, respectively. For the whole
period the fall was 1.4 per cent.
White Corpuscles.—The rise in their numbers during the latent period was equivalent to
a mean of 23.3 per cent. During the paroxysms these were 8.5 per cent. higher than that
of observation period, but fell nearly 9.9 per cent during the intermissions. For the
whole case the rise was 5.5 per cent.
Coarsely granular oxyhile cells.—The maximum increase in their number, 45.6 per cent.,
occurred during the latent period, and during paroxysms and intermissions the rise was 27.1
per cent. and 18.4 per cent., respectively, while for the whole period of 101 days it was 22.6
per cent.
Hæmoglobin.—During the latent period 2 per cent. hæmoglobin increased above that
found during the observation period, but in the paroxysms and intermissions there was a fall
of 15 per cent. and 16 per cent., respectively. For the whole period there was a decrease
of nearly 7 per cent.
BUFFALO I.
The following is a brief account obtained from the ingesta and egesta of a Buffalo
(male) aged three years, which was inoculated with three drops of blood derived from a pony
suffering from Surra.
The period of observation lasted for 14 days.
Body-weight.—The animal was weighed three times a day, viz., at 8 A.M., noon and
5 P.M. It will be noticed that this animal, unlike Buffalo II, lost little in weight during
the period of observation, though there were differences of 8 to 10lbs. in the intervals
between weighings.
On first weighing, the animal registered 359lbs., and 14 days later 357. The mean
weight for this period is 360lbs. It is of interest to note that the animal increased in weight for
some days during the period of observation.
After inoculation there was a gradual loss, until at death the body weighed 2671bs.
At the post-mortem the intestines were found to contain 64lbs. of dung, which repre-
sented in health 17.77 per cent. and at death 23.97 per cent. of the body-weight. No visible
adipose tissue was found under the skin.
Water drunk.—The average daily quantity of water drunk during the period of obser-
vation was 5.47 litres; it slightly increased in the latent period (5.90) and reached a
maximum of 9.54 litres during Intermission III. After this the average quantity gradually
reduced, until, in Paroxysm XII, it was only 3.97 litres. The mean for paroxysms and inter-
missions was 6.54 and 7.03 litres, respectively. For the whole period the average daily
quantity was 6.23 litres.
Water in food.-In
addition to the above .889 kilos were taken in daily in the fooder,
equal to a total of 7.12 kilos (15.66lbs.) ingested. The ratio of water egested to ingested was
in the observation 1: 1.15 ; it increased in the latent period to 1: 1.28, whilst in paroxysms
and intermissions it was 1: 1.00 and 1: 1.06, respectively. For the whole period of 139
days it was 1: 1.12.
Food.—The animal was kept on hay only. The ration contained a daily average of .416
per cent. Nitrogen. During the whole case the animal ingested 2581.04 grammes of Nitrogen
and egested in dung 2,160.84 grammes, giving 420.20 grammes as assimilated Nitrogen. The
total Nitrogen excreted in urine during the same period was 860.278 grammes. Deducting the
amount of assimilated Nitrogen from this, 440.078 grammes are left, which represent the actual
Nitrogen lost. Converting this Nitrogen to its equivalent as flesh, we obtain a loss of 18.659
kilos (41.05 lbs).
The total decrease in body-weight during the whole period was 41.81 kilos (92lbs) so
that the loss by Nitrogen was equivalent to 44.62 per cent., the remaining 55.38 per cent.
being due to CO 2 moisture, etc. No adipose tissue was observed at the post mortem.
Urine.—In the period of observation the average quantity passed was 1,250 cc. which
decreased in the latent period to 987 cc. In the paroxysms and intermissions, it averaged
982 and 912 c.c., respectively. During the whole case the average quantity passed was 1,004
cc. The maximum quantity 1,900 cc. was passed in Paroxysm II, and throughout
the whole case it varied from that amount to as little as 610 cc. in Intermission X. The
specific gravity varied from 1,066 to 1,010 and the Urine taken from the bladder at post-
mortem was 1,040 c,c. containing no Hippuric Acid and only 1.35 per cent. of solids includ-
ing 0.62 per cent. of Urea.
