The new plankton-counting cell is an annular groove machined in a circular plate of lucite. The plate is mounted on a turntable and driven at a rate of about one revolution in six minutes. Counting is done by observation of the rotating sample as it moves through the field of a microscope. This apparatus provides the convenience of the 'trough and flow systems currently used and has the advantage of being a more compact unit.
