It was published in 1880. The book is a hodge podge of information that would be useful to a man of business back in the late 19th Century. There are sections dedicated to penmanship, business letter writing, and the dos and don't of social and business etiquette. One section in the book is called "Unclassified Laws of Etiquette." It's a list of different rules of etiquette that didn't quite fit under the other specific headings (funeral etiquette, etiquette in the home, ect). While the list was written over 100 years ago and some of the suggestions are a bit archaic and random, the advice is still strikingly resonant. It manages to cover many, many of the gaps in etiquette which have  transformed society into a veritable Swiss cheese of incivility. If a man puts these suggestions into practice, he will definitely set himself apart for the other knuckleheads out there trying to land a job or catch the eye of a good looking gal. Looking down the list, I can see several areas were I could use some improvement. Here's to becoming more refined gentlemen!
