### Abstract

For part I see ibid., vol.19, p.563-74, 1986. The phase transition behaviour of the Hamiltonian version of the two-dimensional n-component cubic model is studied along the cubic transition line. 1/n expansion and anisotropy expansion around the 2n-state Potts point are used to determine the phase transition line and the latent heat. The latent heat depends on the value of the coupling whereas the crossover value of n, where the transition changes from second to first order, does not (it is n_{c}=2). The latent heat has an essential singularity at n=2 along the cubic transition line.
