Numbers of Rotifers by Fluid Density
------------------------------------

Description
~~~~~~~~~~~

The data give the numbers of rotifers falling out of suspension for
different fluid densities. There are two species, ``pm`` *Polyartha
major* and ``kc``, *Keratella cochlearis* and for each species the
number falling out and the total number are given.

Usage
~~~~~

::

    rotifer

Format
~~~~~~

``density``
    specific density of fluid.

``pm.y``
    number falling out for *P. major*.

``pm.total``
    total number of *P. major*.

``kc.y``
    number falling out for *K. cochlearis*.

``kc.tot``
    total number of *K. cochlearis*.
