Monte Carlo and series expansion data for the energy, specific heat, magnetisation and susceptibility of the 4-state Potts model in the vicinity of the critical point are analysed. The role of logarithmic corrections is discussed. Estimates of universal ratios $A_+/A_-$, $\Gamma_+/\Gamma_L$, $\Gamma_T/\Gamma_L$ and $R_c^+$ are given. |
