The crossover from a quasi-two dimensional to three dimensional thermodynamic behaviour near the point of the superconducting phase transition in type I superconductors is discussed with the help of a theoretical approach in which the fluctuations of the superconducting order parameter are neglected but the magnetic fluctuations are taken into consideration.
