Here we present the results of pilot polycrystalline study of PrNi_4Si. The X-ray study did not confirm the expected CaCu_5-type structure. Instead of this, the orthorhombic structure with the space group Cmmm was found. The zero-field specific heat was measured in the temperature range 2-300 K. The data were analyzed using the sum of the phonon, electronic, and magnetic contributions to specific heat, respectively. The magnetic part of the specific heat can be well described using the Schottky formula for the 9 crystal-field singlet levels of the pz3 H4 ground-state multiplet of the Pr^{3+} ion.
