Query: DO NOT PURCHASE THIS BOOK! IT IS A FRAUD!!!

The publisher is [...] These books are reprints based on material scanned from old books AND IT IS OUTRAGEOUSLY ILLEGIBLE!!! When you pick up the book you realize that no human has ever touched this to proofread it - the text went from an old book, through a scan, and onto this page - and you cannot understand it. There are goobly-gock typos in every line, no table of contents. Unbelievable what people do for money.
