Abstract | Calandrelli thanks Secchi for his observations and apologizes for having worked ahead on the mathematical formulation for a certain comet dating back to 1811. He details the materials he had on hand for this work - including Cométographie by Alexandre Guy Pingré and Sul progresso degli studi astronomici negli ultimi tempit by Giovanni Santini - and the difficulties he faced therein. Calandrelli concludes by informing Secchi of the calculations he is presently undertaking with the method of Pierre-Simon de Laplace. He adds that if he comes to Rome, he will write to Secchi. |
