BUFFALO No. I.
CORPUSCULAR CHANGES IN THE BLOOD.
Red corpuscles.—Taking 100 as the mean daily number during the period of observation,
there was 4 per cent. increase in the latent period, which decreased 13.6 per cent. and 14.6 per
cent. in the paroxysms and intermissions respectively. For the whole case the loss was 6.1 per
cent.
White corpuscles.—There was a decrease of 5.9 per cent. in their number during the
latent period, which rapidly increased to 3.2 per cent. until a maximum of 13.5 per cent was
attained in the intermissions.
Coarsely granular oxyphile cells.—An increase of 8.1 per cent. occurred during the latent
period, which was further added to 21.1 per cent. in the paroxysms until a maximum of 100.3 per
cent. was reached in the intermissions. In the whole period of 139 days, the total rise in their
numbers was 32.3 per cent.
Hæmoglobin.— Consistent with the increase of red corpuscles the Hæmoglobin was
2 per cent. higher in the latent period than that of the observation but during the paroxysms
and intermissions there was a fall of 12 per cent. and 13 per cent. respectively.
BUFFALO No. II.
The following are the condensed results obtained from the investigation into the ingesta.
and egesta of a buffalo, aged 2½ years, with a view to ascertain the changes which occurred
during a period of observation and later after contracting Surra.
After a period of observation lasting 31 days, this animal was inoculated on the ear with
a drop of blood containing a few hæmatozoa taken from Buffalo No. I.
Body-weight.—From the commencement of this investigation, the animal was weighed three
times daily until death, viz., at 8 A.M., noon, and 5 P.M. There were exceedingly marked dif-
ferences in the daily weights taken at these times, as much as 18 lbs. being lost or gained in the
intervals between the weighings. It will be noticed that during the first 31 days of observa-
tion, which immediately preceded inoculation, the animal lost considerably in weight, although
the appetite was normal, and the animal appeared in good health. This change in weight,
we find, was due partly to loss of flesh and partly to water, CO 2 , etc., and was probably owing
to the changed circumstances under which the animal existed, it having been closely confined
in a building without access to deep water, in which, when free, buffaloes usually lie nearly
submerged for some hours daily.
