In another instance (blackwater fever case) from the same stool L 
obtained: — 
4,000 c.c. of extract with Acid Urobilin band visible to 400 dilutions and Fluorescence (Zinc Acetate) 
to 1,600 dilutions. 
7,400 c.c. of extract with Acid Urobilin band visible to 200 dilutions and Fluorescence (Zinc Acetate) 
to 1,000 dilutions. 
3,000 c.c. of extract with Acid Urobilin band visible to 40 dilutions and Fluorescence (Zinc Acetate) 
to 600 dilutions. 
In all 3,200 litres of fluid showing Urobilin band, or 15,600 litres of fluid showing clearly green 
Fluorescence with Zinc Acetate, in each case in test-tubes fifteen millimetres in diameter.

(b) Faecal urobilin in benign tertian malaria (P. vivax). In 
three cases of this disease the excretion was found to be comparable 
to that found in other pyrexial diseases (in a fourth, Case 8, it was 
much higher, but was only taken on 
one day). 
Case 6 — Maximum day’s excretion

These excretions represent in Cases 6 and 7 about 4 per cent, 
of the patients’ total circulating haemoglobin, the haemoglobmometer 
shows a much greater fall (20 per cent, in Case 7). 
(c) Faecal urobilin in malignant tertian malaria (P- falciparum'). 
Eight cases of disease have been examined for faecal urobilin, and in 
practically every instance a higher output was shown.
