(ii) After unsuccessful inoculation with the Bandicoot hæmatozoon.—When the animal
inoculated is in good health, there is always a great increase in the number of these cells, varying
between 24 and 36 %
(iii) Treatment of Surra with Arsenic.—There is nearly always a steady increase in the
number of the coarsely granular oxyphile cells, commencing shortly after the administration of
the drug, but attaining a maximum after varying amounts have been given.
In these cases, where arsenic is pushed, and death supervenes, there is a gradual decrease,
until at the time of death these cells are very few in number, or more frequently absent. In
the event of the animal under treatment recovering, the cells decrease in number, until they
reach a minimum, when they gradually increase until they attain the ratio found in health.
One can make a fair prognosis as to an animal's chance of recovery from Surra, by daily
observing the number of coarsely granular oxyphile cells present in (one cubic millimetre of)
its blood.
SOME NOTES ON THE AMOUNT OF UREA AND HIPPURIC ACID EXCRETED
IN THE URINE DURING HEALTH AND THE PHASES OF UNTREATED
AND TREATED SURRA.
It is very difficult to draw definite conclusions with regard to the excretion of urea in
paroxysms and intermissions, owing to the fact that the maximum amount of urea is passed at
varying times after the highest temperature has been reached. The maximum temperature
sometimes occurs in the middle of a paroxysm, when, as a rule, the urea would be recorded during
that period, whilst at others the highest temperature occurs, just before the disappearance of the
organism, i.e. at the end of the paroxysm, in which cases the maximum amount of urea appears
in the succeeding intermission.
On reference to the following table the amount of urea, in grammes, excreted by each
animal during health and disease, will be observed under the different headings of Untreated,
Treated or Preliminary Treatment.
