title: Specimen housing unit for cinemicrographic studies in the vertical plane.
abstract: A compact housing unit for low-power (X6 to X50) cinemicrographic studies of microbial specimens in the vertical plane is described. This unit was used successfully to record the development of a "halo" of cells around subsurface colonies of Escherichia coli.
