He goes on to say ‘‘ only 4 organisms out of the 241 were 
shown definitely to belong to the bacillus lactis erogenes type. 
Bacillus cloacee was not isolated in one instance. The cane 
sugar fermenting bacilli numbered 65, while non-cane sugar 
fermenting bacilli reached a total of 176 ’’ (about I to 3). 
Figures obtained from our results are placed beside those 
given by MacConkey to facilitate comparison. Note that the 
difference is not very marked. Lactis erogenes is not a com- 
mon organism in human feces in this country, but it 1s met 
with in 6 of the series; it is entirely absent from 3 only. 
Cloace has been found occasionally (vide Table IIc). 
The proportion of saccharose and non-saccharose fermen- 
ters is 348 to 852 (about 1: 24). This increase in the non- 
saccharose fermenters in India, coupled with the fact that 
coli communis is a rare organism in faeces, emphasizes the dif- 
ference between the two parts of the world, when considered 
from the standpoint of the water analyst. 
It should be mentioned here, that the samples of human 
feces used by us, were taken from the native population, who 
are almost entirely vegetarians ; it would not appear that the 
diet had any very great influence on the bacteriological con- 
tents. 
In cowdung MacConkey (1905) gives the following per-

He also states ‘‘ none of the organisms isolated of group 
4 were identified as bacillus lactis erogenes type.’’ These 
percentages appear to be worked out on 48 colonies from 
six samples of cowdung ; so the data are rather small; it will 
be observed that the relation between the four groups in this 
country is very different from that in Europe. Lactis erogenes
