Summary: From the introduction: The partition function for the two-dimensional Ising model has been represented by \textit{S. Samuel} in the form of an integral over anticommuting variables [J. Math. Phys. 21, No. 12, 2806--2833 (1980)]. Several authors have justified the representation by connecting it with the underlying fermion field. In this note, by using fermionic coherent states, the same programme is carried out in a straightforward way.
