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. |
