The divergences of the dielectric and elastic constants of gels filled with aluminum particles near the percolation threshold are investigated on the same samples. We found that the ratio of the two exponents s of the dielectric divergence and of $s^{\prime}$ of the elasticity divergence is $s^{\prime}/s=0.80 \pm 0.05$, showing definitely that $s^{\prime}< s$.
