content: This may have been a fine work in its original form, but this edition (Wilder Publications, 2008) is so shoddy, it isn't worth the effort to try to read it. Based on my own experience with OCR software, I would guess that this publisher scanned an old copy, translated it to text, then reformatted it, and printed it. There is no evidence that anyone proofread it prior to printing. It it doubtful that it was even run through a spell-check program. Periods are missing at the ends of sentences; words are left out; "d", "h", and "b" are confused; apostrophies are inserted randomly (probably fly-spots on the original), "and" repeatedly appears as "an", "modern" almost always appears as "modem", etc. ad infinitum.I read through about a fourth of the book before giving up in exasperation.
