The first method distinguishes between uncial or majuscule, and cursive or minuscule; the second between papyrus, vellum or parchment, and paper (for further details see Manuscript and Palaeography); and the third distinguishes mainly between Gospels, Acts and Epistles (with or without the Apocalypse), New Testaments (the word in this connexion being somewhat broadly interpreted), lectionaries and commentaries.
He afterwards became keeper of manuscripts at the Bibliotheque Nationale in Paris, and professor of palaeography at the Ecole des Chartes.
It practically created the science of Latin palaeography, and is still the standard work on the subject.
It contains nearly io,000 MSS., including many magnificent illuminated missals and Bibles and a number of valuable Greek and Latin texts, 242 incunabula and 11,000 printed books, chiefly dealing with palaeography; it is in some ways the most important of the Florentine libraries.

But the real auxiliary sciences to history are those which deal with those traces of the past that still exist, the science of language (philology), of writing (palaeography), of documents (diplomatic), of seals (sphragistics), of coins (numismatics), of weights and measures, and archaeology in the widest sense of the word.
