In this paper the author presents a brief description of a projective connection on the circle. He shows how the Neumann system is connected to the stabilizer points of the coadjoint orbit of the Virasoro-Bott group. It is shown that a certain quadratic function of a projective field satisfies the C. Neumann system.
