Euclid's Data, [electronic resource] : restored to their true and genuine order, agreeable to Pappus Alexandrinus's account of them, in his Preface to the Seventh Book of his Mathematical Collections. By Richard Jack, Teacher of Mathematicks. In this Edition care hath been taken, to correct the errors in the Enuntiations of several Propositions, and their Demonstrations, contained in the Manuscript Copies, as well as in the other Editions; and such Propositions as were wanting are here restored, and the supernumerary Propositions, contained in the other Copies, are here made Corollaries to the Propositions they respectively belong, as mentioned by Pappus.
