| Abstract | Calandrelli speaks of having compiled all the observations done in Bologna over the past year for the rectification of a certain Meridian circle. Then, he describes some of the processes he went through and experimented with the instrument - some of which were taught to him by Andrea Conti. He concludes the letter asking for Secchi's opinion on his work - particularly regarding the corollary results listed at the bottom of the second page. |
