The growth in this was fairly rapid and the smell very slight at the
end of a week. A piece of washed sheep grain worked in this culture
at 37° C. for four hours was considerably reduced, the grain was
not attacked, the action differing in this respect from a prolonged
puering. This mixed culture was grown in various other nutrient media,
gelatin, gelatin and mineral salts, broth made from sheep and calf
fleshings, etc., with practically the same results. In no case did the
bating action equal that of dung, and was insufficient for practical
purposes.

A cursory bacteriological examination of dung will show that the number
of species of bacteria it contains is very large, but on making a
plate cultivation from a sufficiently dilute infusion of fresh dog
dung, most of the colonies developing appear to belong to four or five
species. The following is a list of all the organisms which, so far as
my knowledge goes, have been isolated from different kinds of dung:--
