     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.

 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
