Based on classical but apparently little known results due to Razzaboni, the integrable nature of Bertrand curves and their geodesic embedding in surfaces is discussed in the context of modern soliton theory. The existence of parallel Razzaboni surfaces which constitute the surface analogues of the
## Abstract In this paper a system of coordinates for the effective divisors on the Jacobian Variety of a Picard curve is presented. These coordinates possess a nice geometric interpretation and provide us with an unifying environment to obtain an explicit structure of algebraic variety on the Jaco
