I have owned print copies of the Loeb edition, but I have been looking for free downloadable PDF version of this edition for a very long time. Not sure why it took so long to find it, but I find today that Google has digitized it and has it available for free download. I suggest downloading a copy as this is the best and maybe only free side-by-side Latin English version available. Current editions are co-edited by Martin Ferguson Smith, who has extensively revised, added his own material, and even published a separate edition at Hackett Publishing. This download appears to be from the first edition, revised in 1924, and it contains an introduction which I have not seen which may be a good find in itself.
Here is the Wikisource page referencing the entire Loeb Series. Our target is Loeb 0181!
Pressing the "external scan" link takes you to Google.
And clicking the "Download PDF" button starts the download!
