<h2>
Numbers of Rotifers by Fluid Density
</h2>

<h3>Description</h3>


<p>The data give the numbers of rotifers falling out of suspension for
different fluid densities. There are two species, <code>pm</code>
<EM>Polyartha major</EM> and <code>kc</code>, <EM>Keratella cochlearis</EM> and
for each species the number falling out and the total number are
given.
