This rose in a crescendo of cannonading with loud explosions overhead. Numerous people saw a body streak across the sky and plunge to the ground.

In 1770 appeared his Dissertazione sopra un legno fossile co-authored with Giambattista Toderini; it was concerned with explaining the origin of fossil wood.
His report of electrical experiments, Della elettricità: lezioni di fisica sperimentale fatte nella Università di Modena il primo anno del suo rinnovamento, was published at Modena, 1772.
