PREFACE.

In editing the books of Galen that are inscribed Περὶ χρείας μορίων On the Use of Parts, I have used the following codices:

1. Urbinas 69 (U). It is a parchment manuscript of the largest format, written in the tenth or eleventh century, well-preserved except that the final leaves contracted damage from moisture or location, which caused the words of the last lines to either vanish entirely or become very obscured. It contains one hundred and ninety-five leaves, or twenty-five quaternions, with five leaves of the twenty-fifth quaternion missing, by which loss the end of the seventeenth book perished; for it ends with the words "and they remove from it the providence regarding living creatures. Proposing" (vol. IV p. 364 K). The quaternions are marked in the upper margin with Greek letters, and in the lower with so-called Arabic numerals, by a more recent hand. On individual pages there are thirty-nine or forty-one lines. Accents and breathings are very often missing, and sometimes added by a second hand. The so-called subscript iota I found nowhere, and the adscript in only a few places. The scribe did not use abbreviations except for the most common ones. I myself collated books I—VI, VIII, XII, XIV, XV, XVII in the year 1877; the others were collated by Friedrich Spiro in 1904.

Urbinas is the most ancient of all the codices and likewise the best. For it alone exhibits a great number of true readings. For example, I will bring forward these: p. 3, 14 (of this edition) ἐπὶ γῆς on earth, 5, 7 ἐκγλύψαι to engrave, 7, 9 ταῦτα these (also Theophil.), 9, 16 ἀντιλαμβάνεσθαι to take hold of (also Theophil.), 11, 11 κορυφάς summits/crowns (also Hippocr.), 18, 8 ἀμφισβητεῖν κάλλους to dispute beauty, 23, 24 κλω-μένων being twisted/spun, 31, 19 μηδαμῇ in no way, 85, 24 οἷς to which, 86, 20 διαπειράμενον making trial/testing,
