Admittedly, I have not plowed through this entire book, which appears to be a novel of some sort. I was browsing free books in Kindle and saw the title and thought I might as well download it since it was free. One would think the subject was candidiasis or maybe alcoholism and the temperance movement. There is a long preface to the fourth edition where the author talks at length about the Poor Act in England and farming but having scanned many pages of this work, I really have no idea what it's about. If you are getting it because of the title, do not bother.
