  Phase behaviour of the Stockmayer fluid is studied with a method similar to
the Monte-Carlo annealing scheme. We introduce a novel order parameter which is
sensitive to the local co-orientation of the dipoles of particles in the fluid.
We exhibit a phase diagram based on the behaviour of the order parameter in the
density region 0.1 \leq {\rho}\ast \leq 0.32. Specifically, we observe and
analyse a second order locally disordered fluid \rightarrow locally oriented
fluid phase transition.
