 not straight; they are more or less wavy; and they are 

 motile.

(a) Vibrio rugula consist of rods of about 0*008 to o - oi6 

 mm. in length, and curved either like a C or like an S. 

 They are single, or form chains of two. Their protoplasm 

 is always slightly granular. They are found in putrefying 

 organic substances, and often form continuous masses, the 

 individuals interlacing in all directions.
