are indicated. page 42.
Antitheses of the Censor and of Apelles. p. 43.
Figure in which the errors of the Censor are revealed in practical examples. p. 47.
Corollaries in which the errors of the Censor are examined. p. 49.
Ch. XI. The absolution of Apelles made by the Censor, whether while he speaks for him or while he seems to speak against him. p. 53.
The first falsehood which the Censor foisted upon the Reader is shown, namely that the Table of Apelles, and the more accurate disquisition (except for the last letter, from which, however, no comparison is brought), are prior in both writing and printing for the most part, [proven by] the very first letter of the Censor. page 56.
And thus it is also demonstrated that a continuous thread and connection existed between the letters written by Apelles. page 57.
The third point, in which the delay of time, within which Apelles is argued by the Censor's rod to be inconsistent in his opinion, is demonstrated to have been very small, and of almost no moment. page 59.

Approval of the writings of Apelles from the mind of the Censor. page 65.
