  The distribution of masses of clusters smaller than the infinite cluster is
evaluated at the percolation threshold. The clusters are ranked according to
their masses and the distribution $P(M/L^D,r)$ of the scaled masses M for any
rank r shows a universal behaviour for different lattice sizes L (D is the
fractal dimension). For different ranks however, there is a universal
distribution function only in the large rank limit, i.e., $P(M/L^D,r)r^{-y\zeta
} \sim g(Mr^y/L^D)$ (y and $\zeta$ are defined in the text), where the
universal scaling function g is found to be Gaussian in nature.
