Uyeda's description of this organism differs from Bacterium solanacearum, as I have cultivated it, in the following particulars: *Kig. 127.—Agar stab and streak cultures of Bacillus nicotianae Uyeda, showing a brown stain in the upper part, the lower portion of each being unstained. (After Uyeda.) fFic. 128.—Bacillus nicotianae Uyeda, from an agar-plate culture 2 weeks old, showing development of the brown stain in and around the colonies. (After Uyeda.).
