You are advised that the text has been transcribed and then checked once only - in view of the quantity of text ie over 520 pages in volume VI alone, I find that this still leaves a few errors scattered through the text when my attention has wandered or when the eyes grow tired - I should be grateful for details of any obvious problems eg broken links and obvious errors

NB Spelling has in most cases been left as it appears in the original - although where there appears to be a printing error, rather leave it, I have on occasion made corrections - and hopefully by the time this appears on the web site I will have completed the corrections from the Errata.

Volumes i and ii are not available at the present time - therefore there are no cross-references etc
