In Dunham's solution gives indol in all
dlutiOns, in all tubes.
Gas formed in all fermentation tubes
in amount and character to that given
by fccal organisms.
Strong production of hydrogen sulid
by method of Schar1irger; this points to

Slight production Of hydiog sulfld.
No growth in phcnolizei DunEam's So
luton at ~ degrees Ccntigrade.
Bacterial forms ale those found in up
per LAYERS of soil. pollution species be-
inb practically absent. The one case of
indol production and the formation Cf
some hydrogen Sulfid can be taken as a
measure of the excessive dlution of any
communicating material iinding its way
into the reservoir.
