The original book has been scanned and then read with ‘OCR’
(optical character recognition).
This is not totally error-proof and a few misprints will be found in this text,
though it is possible to deduce the correct meaning throughout. It may
help to know that the £ sign is sometimes misread as the letter E!
We have experimented with producing a true facsimile version of the original
book but it produces an extremely large file that would be very difficult for
most people to download.
