†. In the margin it is read that this also was collated with the prototype. Psellus composed about 30 very learned letters, according to the testimony of Casaubon. All these lucubrations, moreover, seem to have been made in the form of letters. Whence I infer that these are the letters of Psellus mentioned by Fabricius in volume V, page 48 of the Bibliotheca Graeca. But the beginning of the first, which he cites there, I do not find here. He also mentions in the same place that nine of his letters from these were published by Allatius after the Syntagma de Simeonibus in Greek and Latin. See the note. This must still be observed: the work of Psellus on the four mathematical disciplines, which appeared in Greek at Venice in 1532 in 12mo, has nothing in common with these lucubrations. In the old catalogue, only this inscription is found: "Letters of Psellus and various expositions on various passages of Plato."
