Spore-formation is independent of any deficiency of nourishing material. The spores are oval, bright, of about 0001 to o'oo2 mm. in length, and about o'ooo6 to cooi mm. in thickness. They do not stain in ordinary dyes, and hence form a great contrast to the bacilli. This bacillus is very common and widely distributed ; it N 2.
