Melting of a two-dimensional electron lattice and a two-dimensional dipolar solid are studied using molecular-dynamics techniques. The existence of hysteresis and latent heat of melting are observed, and the melting transitions in the two cases are found to be first order. For an electron lattice the melting occurs between GAMMA=129 +- 3 whereas in the dipolar solid it is between GAMMA=62 +- 3, with a transition entropy of 0.3 k/sub B/ per particle for both the systems.
