Abstract
IF small particles are suspended in a fluid in which there is a velocity gradient, non-spherical particles will become orientated whereas spherical particles will not; this orientation alters the light transmission through a suspension of such particles. Thus the turbulence produced by shaking a test-tube containing a suspension of rod-shaped bacteria can be seen as a ‘swirl’ whereas a coccal suspension shows no ‘swirl’.
