  The aim of the paper is to demonstrate the use of the Galerkin method for
some kind of Volterra equations, determininistic and stochastic as well.
  The paper consists of two parts: the theoretical and numerical one.
  In the first part we recall some apparently well-known results concerning the
Volterra equations under consideration. In the second one we describe a
numerical algorithm used and next present some examples of numerical solutions
in order to illustrate the pertinent features of the technique used in the
paper.
