The translation follows on pages 7-12, with notes on page 13 and references on page 14.
I have attempted to give as literal a translation as possible. Where I was forced to add in words or phrases not in the Greek, I have used round brackets to enclose additions which are designed to assist the reader but are not technically essential, and square brackets for additions without which the sense would be obscure or misleading.
I have throughout used the Greek text edited by Tannery .
I would like to thank Professors V. Katz and F. Swetz for their extremely useful comments and references.
