HORSE No. LXXXIX.
Australian Gelding, aged. This animal was a caster on account of lameness, but was otherwise in good health
and condition.
This experiment was undertaken with a view to determine: —
(i) Whether the administration of Arsenic immediately upon the appearance of the Surra hæmatozoon would prove
destructive to the organism, when the disease was contracted by gastric ingestion of blood, in a manner
somewhat similar to that in which it ordinarily occurs in nature.
(ii) The ratio between the quantity of water drunk, irrespective of the amount in the fodder, and quantity of
urine passed during the 24 hours.
(iii) The excretion of Nitrogen as Hippuric Acid and urea, during the periods of health, latent period of the
disease, paroxysms and intermissions, the animal being under treatment during the latter two periods.
Date.
1893.
