| Abstract | Calandrelli explains the equation for reducing a number of observations. He uses data from July 20th and corresponding data from "Catalogo Brittannico" for the month of July in his demonstration. He waits for Secchi to employ this equation on his observations to that Calandrelli can complete his own caculations for the parabolic orbit. These observations are undertaken in search for a new planet. |
