With these Piazzi observed the stars contained in his celebrated Catalogue of 7641 Stars (1814); this work led him to the discovery of the first minor planet, Ceres, on the 1st of January 1801. The activity was revived in 1857, when a meridian circle by Pistor and Martins of 5-in. ap. was mounted; a 91/2-in. refr. by Merz has been used for spectroscopic work.
