Spore-formation in Vibrio-like (c) and Spirillum-like (a b, a) Schizomycetes. F. Long rod-like form containing a spore (these are the so-called "Köpfchenbacterien" of German authors). G.

Spirillum containing many spores (a), which are liberated at b by the breaking up of the parent cells. K. Germination of the spore of the hay bacillus (B. subtilis)—the axis of growth of the germinal rodlet is at right angles to the long axis of the spore. L.
