  For the statistical multifragmentation model the critical indices
$\alpha^\prime, \beta, \gamma^\prime, \delta$ are calculated as functions of
the Fisher parameter $\tau$. It is found that these indices have different
values than in Fisher's droplet model. Some peculiarities of the scaling
relations are discussed. The basic model predicts for the index $\tau$ a narrow
range of values, $1.799< \tau < 1.846$, which is consistent with two
experiments on nuclear multifragmentation.
