This work is one that I have found to be entertaining from several reads. This is definately not a sit down and plow through it book, but rather one can pick up and put down as needed. As a whole, I found in interesting from a perspective of much of what we consider normal everyday language these days was only a couple of hundred years ago considered the "ebonics" of the time. It does very much carry the tone and verbage of the day, which may disinterest some, but fans of Victorian, Edwardian, or Elizabethan period speech should adore this, as well those whom are interested in such through some of the more fanciful spin offs such as Steampunk fans.
I would say that this if you are looking for new (old) ways to spew forth vulgar phrases you will be disappointed, but if you are looking for phrases and even the occasional insult of Shakespearan wit, you can find more than a few gems within this book.
