+=acid and gas, acid and clot, Indol formation, Liquefaction
of Gelatine, etc., as the case may be.
-=no acid and gas, no Liquefaction of Gelatine, etc.
The Nos. under the signs equal days, e.g. no Liquefaction after 14 days growth.
All non-motile and all non-Indol forming organisms were also tested on 5% Gelatine at 37° C. for 11 days. The Cultures were then cooled down to see if Liquefaction had oc- curred or not.

407 Cultures
MacConkey (1909) in his examination of human excreta obtained 21 varieties of Lactose fermenting Bacilli out of 178 cultures examined. But 146 out of these 178 cultures were confined to five varieties, the remaining 32 cultures being divided up among 15 varieties and therefore not of much practical importance.
The chief organisms isolated were :—
No. 4 B. Grünthal
No. 5 B. Vesiculosus
No. 34 B. Coli Communis
No. 35 B. Schafferi
No. 71
No. 72 B. Neapolitanus
