common in water, and the sunlight experiments showed that 
it was not infrequently met with. It has been found in both 
cowdung and human feces. 
Bacillus No. 9.—This organism very much resembles 
acidi lactici, with the exception that it gives Vosges and 
Proskauer’s reaction. It has only been isolated once from 
feeces, namely, from cowdung. In the month of February 
it was found to be very common in the Water-supplies of 
Vellore and Gudiyattam, and rarer in a few others. The 
prevalence of this organism in several places tends to show 
that it is a separate species, and that it is not an odd specimen 
of acid lactici, which (according to some authorities) has 
acquired the power of giving Vosges and Proskauer’s reaction. 
Nothing can be stated as regards its power of resisting the 
action of sunlight. 
Bacillus No. 33.—This bacillus is similar to coli communis 
except that it ferments adonit. It is a moderately rare organ- 
ism, appears to be more common in human feces than in 
cowdung. It is occasionally found in water samples. For 
a long time we looked upon it as being confined to human 
feces only, but extended work proved this to be incorrect. 
It possesses the power of resisting sunlight to a moderate 
degree and belongs to class II. 
Bacillus Pneumon@e and Rhinoscleroma No. 68.—This 
organism is usually found in small numbers in human feces, 
cowdung and in water-supplies. 
Bacillus No. 67.—Is common in samples of faces of both 
human beings and cattle. It is also met with fairly commonly 
in water-supplies. 
Neapolitanus No. 72, and Bacillus No. 74.—This is a 
fairly common organism and remarkably constant at all times 
of the year and in all samples of human feces and cowdung. 
It is also constantly prevalent in water-supplies. 
Bacillus Nos. 73 and 75.—This is an organism that has 
been isolated from cowdung and human feces and is fairly 
prevalent in water-supplies. It has also been isolated from 
the trenching ground earth a considerable time after pollu- 
tion had taken place. It is undoubtedly a resistant organism, 
but further work is necessary as to which class it should go
