Charts relating to the Cows which had Haemoglobinuria. 
The accompanying charts relate to two cows (II and IV) which 
served as Controls, and to the five cows (1 to 5) which were treated. 
The object of the charts is to show graphically the chief facts recorded 
in the protocols : the sudden onset of fever ; the appearance of parasites 
in the blood and their increase in numbers ; the period when haemo¬ 
globinuria set in; the effect of treatment upon the foregoing symptoms 
and upon the parasites. 
The numbers running along the top of the chart indicate the days 
on which the animal was observed, the inoculation being recorded 
on the first day, or subsequently when the animal received two inocula¬ 
tions. Beneath the day numbers the presence of parasites in the blood, 
irrespective of their number, is indicated by + signs. The average
