Manfredi, in behalf of Riccioli, endeavours to answer the Objections of Angeli, and this latter replyes to Manfredis'' Answer. The substance of their discourse is this following.

Although the Arguments of Riccioli be many, yet the strength of them consists chiefly in these three:

In Answer to the first of these Arguments, Angeli denieth the Minor, which Riccioli pretends to prove thus; Rh
