Average excretions of urinary urobilin in malignant tertian malaria 
(Cases io, 12, 17, 19, 20). 
Maximum excretion in twenty-four hours (Cases 20 and 17) 
0 2 to 0 30 grams. 
Maximum total excretion in seven days (Cases 17 and 12) o'6 
to 07 gram. 
The amount of urobilinuria (even if considered in comparison 
with body weight) bore no apparent relation (1) to the degree of 
pyrexia; (2) to the fall of the haemoglobinometer readings during 
the pyrexia; or (3) to the absolute numbers of parasites present in 
the blood. 
(d) Special high excretion in malignant tertian malaria. In four 
cases the excretion of urobilin was so much higher that they will be 
mentioned separately and in more detail. In Cases n, 13, and 23, 
t e patients were young, and large numbers of parasites were present 
wit correspondingly severe symptoms; in Case 21 the patient was 
older and, though the parasites were much less numerous and the 
pyrexia less marked, he was markedly prostrated by his attack. 
may mention that the urine in these cases became extremely 
dark on standing in daylight, after acidification, and that the 
a” 0 uro remained visible in two instances until the urine 
was diluted to one hundred and fifty volumes. Cases 13 and 21 
were constipated at the time the high-days' output took place. 
give in each instance the maximal twenty-four hours’ output 
and the total excretion for seven days, and have also determined 
the percentage relation between these amounts and the normal 
circulating haemoglobin of the patients.
