The object of the work undertaken by Vedder and Duval was to show that the acute dysentery of this country is caused by the bacillus of Shiga. In order that a given bacillus may be regarded as identical with Bacillus dysenteriæ, it must show, of course, the same cultural and morphological characteristics as standard cultures of
