Plato’s Apology of Socrates and Crito [PDF ebook] 
With Notes Critical and Exegetical Introductory Notices and a Logical Analysis of the Apology

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. It is hoped that this work will be found useful by those who commence their study of Plato with the two pieces contained in it, as it is for their wants that the notes are intended.
