Content of type 'appendix'

Appendix: Book XIV (by Hypsicles) & Note on Book XV

This supplement to Euclid’s Book XIII. is worth reproducing for the sake not only of the additional theorems proved in it but of the historical notices contained in the preface and in one or two later passages. Where I translate literally from the Greek text, I shall use inverted commas; except in such passages I reproduce the contents in briefer form.
