  For the two dimensional random bond disordered Ising ferromagnet, we measured
bulk data of the magnetic susceptibility ($\chi$) and correlation length
($\xi$) up to $\xi \simeq 536$, with the use of a novel finite size scaling
Monte Carlo technique. Our data are exclusively consistent with normal
power-law critical behaviors with only one singular point at criticality,
disproving the existence of Griffiths singularity even in an extremely deep
scaling region. The critical exponents of $\chi$ and $\xi$ increase
continuously with the strength of disorder.
