He is made to say that he writes this letter for the particular purpose of communicating to his father and their friends in Florence, the news, which had reached Lyons, of the arrival of Verrazzano from his wonderful and successful voyage of discovery, and that he had advised his parent of all other matters touching his own interests, by another conveyance.  It might be supposed and indeed reasonably expected in a letter thus expressly devoted to Verrazzano, that some circumstance, personal or otherwise, connected with the navigator or the voyage, or some incident of his discovery, besides what was contained in the enclosed letter, such as must have reached Lyons, with the news of the return of the expedition, would have been mentioned, especially, as it would all have been interesting to Florentines.  But nothing of the kind is related.  Nothing appears in the letter in regard to the expedition that is not found in the Verrazzano letter. [Footnote:  Mr. Greene, in his life of Verrazzano, remarks that it appears from Carli’s letter, that the Indian boy whom Verrazzano is stated to have carried away, arrived safely in France; but that is not so.  What is said in that letter is, that Verrazzano does not mention in his letter what he had brought home, except this boy.] What is stated in reference to the previous life of Verrazzano, must have been as well known to Carli’s father as to himself, if it were true, and is therefore unnecessarily introduced, and the same may be said of the facts stated in regard to Brunelleschi’s starting on the voyage with Verrazzano and afterwards turning back.  The particular description of Dagaghiano and Rustichi, both of Florence, the one as a man of experience and the other as a student of cosmography, was equally superfluous in speaking of them to his father.  These portions of the letter look like flimsy artifices to give the main story the appearance of truth.  They may or may not have been true, and it is not inconsistent with an intention to deceive in regard to the voyage that they should have been either the one or the other.  A single allusion, however, is made to the critical condition of affairs in France and the stirring scenes which were being enacted on either side of the city of Lyons at the moment the letter bears date.  It is the mention of the expected arrival of the king at Lyons within three or four days.  It is not stated for what purpose he was coming, but the fact was that Francis had taken the field in person to repel the Spanish invasion in the south of France, and was then on his way to that portion of his kingdom, by way of Lyons, where he arrived a few days afterwards.  The reference to this march of the king fixes beyond all question the date of the letter, as really intended for the 4th of August, 1524.
